You will find the best ATX v3.x & PCIe 5.x Ready PSU Picks 2025 in this article. PSUs compatible with the most recent ATX v3.x specs are way more expensive than the ones meeting the requirements of the previous ATX specs. You will probably wonder whether you should invest in them or buy an older-generation PSU and save money. Although none of today’s graphics cards has high enough power spikes to justify the demanding ATX v3.x requirements for power excursions, as it calls them, no one knows what the future GPUs will bring. You can read more on the ATX v3.0 specification in this article. We also have an English section on our Discord server if you have any questions.
The newer ATX v3.1 and PCIe 5.1 standards are already in effect. Since the significant difference between ATX v3.0 and 3.1 is mainly in the connector, from 12VHPWR to 12V-2×6, with the high-power cables remaining the same, I expect most ATX v3.0 PSUs to get slight updates for ATX v3.1 compatibility. A downside of the ATX v3.1 spec is that it allows for a lower hold-up time, from 17ms (ATX v3.0) to 12 ms.

Hello,I am was looking at the results and decided to take a look at a 850W affordable PSU and I found myself in a battle between these:Price i USD$ in my country:
My future build will be R5 7600/R77 800x3d and a future upgrade to a 4071 Ti .For what I’ve seen 850W should be enough for this build right?
be quiet! Pure Power 12 M 850W-152$,100W-164$
Super Flower Leadex VII XG 850W-166$,1000W-193$
Or should i look for another option?
Thanks!
for your build is ok.
καλησπέρα,
Εχω μπερδευτεί λίγο, ανάμεσα στα CORSAIR CP-9020262-EU RM750E V2 , CORSAIR RM750E V3 (ποιες οι διαφορές? ) και στο CORSAIR CP-9020199-EU RM750X πιο να επιλέξω?
Ευχαριστώ.
RMe ειναι χαμηλότερης κατηγορίας αλλά το V3 είναι ΑΤΧ v3.0. Προσωπικά θα πήγαινα στο RM750x αν δεν με ένοιαζε τόσο πολύ το ATX v3.0 και μετά στο RM750e v3
Hey man. I need a new Psu. My dark power10 750w struggels with 4090 and 16core CPU. IT makes some strange noises…. looking to buy a bequiet dark power pro 13. 1300 or 1600watt. Is there something wrong with this psu’s?
what do u mean strange noises?
Like coil whine
Really appreciated this article, it helped me understand what to look for in a PSU! So for my new PC I have a 13600KF+RTX4070 combo. I was thinking of a 750W or 850W PSU, preferably a silent one with zero RPM mode. Also, I do not have a lot of cable management space in my case, so the Corsair SHIFT series probably doesnt work. I was thinking of the Seasonic GX ATX 3.0, but it is hardly in stock in my country. Do you think it is a good PSU, or do you have other recommendations?
Thanks!
Seasonic is good yes, you could also look at the Thermaltake GF3 750W
Gonna be reposting here as it seems my comment went from awaiting moderation to gone for some reason.
Hello! I’m considering upgrading (or sidegrading) from the Core Reactor 750w to the Pichau Nidus 850w and noticed it has the Cybenetics certification yet it’s not listed here nor the Cybenetics website, wondering if there’s any reason for that or if it’s gonna be updated later on.
Also noticed that for the SF-G850M and SF-G1000M (Super Frame PSUs) the pictures at the end of the document clearly show they’re named SF-B850M and SF-B1000M, did they get revised and name changed later on? Wasn’t able to find anything on the B variants so just wondering! And it seems like their components are also not listed on the Cybenetics document.
Lastly, found the Nidus 850w, SuperFrame 850w and Cougar GEX X2 at the same price here, with that in mind which one would you pick? And also why, if you don’t mind :).
Love the content, keep up the great work, it is very much needed and appreciated!
Yes, moderation is required because we had tons of spam in the past, sorry.
Nidus 850W, will check it with Cybenetics once they return from vacations. Good catch there!
We use the name they provide us. Usually the PSUs we get are pre-production units, so labels and naming schemes can change.
Thank you!

My Corsair PSU RM1000I that is 7 years old keeps shutting down with my 4090 RTX and after alot of troubleshoot it is the PSU.
My spec is
7800x3D
RTX 4090
2 X 16GB ram 5200mhz
But im getting confuse on the PSU guides because you recommend alot of PSU with the connector you dont recommend anymore (12+4 pin)?
So what should i get for a PSU? Seems the best guide is to stick with PSU that have 2x 8pin to 12VHPWR? But then there isnt alot of PSU to select from? The Corsair RM1000e seems like a cheap choice? What would you recommend?
I think you got confused. The connector (12+4) is fine. It is just better if you get a PSU with 2x 8pins on the PSU side for various reasons.
RM1000e is good, but also check RM1000x Shift.
The stock in denmark is right now pretty low on the high end of PSU
What would you recommend?
Pricetag in dollars
Corsair RM1000x SHIFT – 249,53
Corsair RM1000e V2 (ATX3.0) – 198,13
Corsair HX1500i (2023) – 351,16
Cooler Master MWE Gold 1250W V2 ATX 3.0 – 212,81
NZXT C-Series Gold C1200 – 234,4
Should i get more watt then 1000 for the build?
My spec is
7800x3D
RTX 4090
2 X 16GB ram 5200mhz
1) Corsair HX1500i
2) NZXT C1200
3) Cooler Master MWE Gold 1250
Your system doesn’t need such a strong PSU though, a 1000W will be fine since your processor is highly efficient. Stronger PSU will make you more future proof though.
What a great resource this is! Thank you!
I have all parts for my build minus the case (Lian Li EVO XL) and the psu.
My build spec
Custom water cooled cpu (13900k) and gpu (Asus Strix RTX 3090 OC, *will be switching to 4090 or 50 series next year) with x3 420mm radiators since I plan to overclock (I realize that it’s probably overkill), 32GB DDR5-7600.
I am looking for advice on a psu. I’m not sure if 1000 W will suffice or if I need to look at 1200 W and above. I am looking at the offerings from FSP and Super Flower in both 1000 and 1200/1300 W respectively. Which do you think would be best suited for my build? The Hydro Ti 1000w, Hydro PTM 1200w, the Leadex VII 1000w or the Leadex VII 1300w? I appreciate your advice. Thanks!
I would go for a 1200/1300W for more headroom. Leadex VII 1300W

Is a RM850X good enough for a 7800X3D and a 4070ti, also taking into account any transients? Appreciate your work and thanks for reading.
Yes, it is more than fine for this system.
Thank you for answering, much appreciated.
Hi and THANK YOU for your work.
I have build my new PC:
7800 x3dx = Asus B650e-e
2x 16 gb 6000 mhz cl 30 ddr5
asus rog strix oc 4090
I have an older PSU and wanted to upgrade to ATX 3.0
I have my eyes on ASUS aura gaming Gold 1000w and FSP HYDRO TI Pro 1000w titanium. They are pretty much same price in my country, so which would you take? 🙂
I cant decide, i am “asus fanboi” but wanted the absolut best PSU for my system (PSU is hidden in my lian li dynamic xl, so looks on psu dosnt matter)
I would go for the FSP unit!
How about the 12+4-pin PCIe 5.0 cable? trying to understand the 12V-2×6 you wrote about – not sure i understand:/
Hello Aris,
Congratulations on your new lab!
I have all my PC parts but I cant decide on a PSU.
I wanted to ask for your advice.
My setup: I9-13900K, Gigabyte rtx4090 gaming OC
Looking for the 1200W range.
Is your list updated in this range?
I have access to: the FSP hydro ptm pro 1200W (atx 3.0)- 280$
Also for the Deepcool PX1200G -260$
Corsair RM1200x shift – 361$ (which I hesitant about because of side clearance at the fractal north)
what would you choose?
should I go out of my way and try and get something else, overseas from Amazon?
Thank you for everything and any advice!
I would go for the FSP unit.
Hello. I see you give recommendation to Cooler Master v750i. And noise was only 23db.
But it’s older brother 850i saw almost 33db in it’s review? Why so different? Thanks.
The default fan speed profile. But in this units you can adjust the fan speed profile easily, through software.
Hi, great site. I’m after a future proof 3.0 psu for mini itx build…..sfx or sfx l , , I’m purchasing a rtx 4090 and running 64gb ram with Intel 12700k cpu, which power supplies would you recommend?
Corsair SF1000L is a great choice and you can also look at the Thermaltake SFX 1000, for more power. The SilverStone SX1000R is decent, too.
Hi Aris,
Congrats on the big move! Very Excited for the New Lab. Have you already taken a look at the ATX 3.0 variant of the Corsair HX-1500i or will you be reviewing it in the near future?
I just asked Corsair to send me one 🙂
NZXT C1200 had a bad coil whine at 60-75w usage when my system was idle without a GPU installed. It went away when I installed my GPU.
I moved to a Thermaltake GF3 1000W and didn’t experience any issues and the cables are easier to work with.
Both use exactly the same platform, CWT CSZ
Hello, What do you think of the Be Quiet Straight Power 12? I can’t find many reviews on it. Was thinking of buying one when it releases first week August in Canada 🇨🇦 hoping you got one in for review.
I have samples of that, but I have to set up the new lab first to check them.
I wish a quietest possible one for an RTX 4090 based system. With NO COIL WHINE! What’s is the current “crème de la crème” PSU in those regards?
As it seems there is no guarantee on that. PSUs that work fine in my set ups, can have coil whine in others.
Thanks. So if you were me which PSU would you buy today, for a new build? In other words, what would be the best bet?
Hi, I’m looking to buy a new PSU and like with other PC parts, I enjoy trying to understand what I am buying. Your site(s) are a great help. Appreciate the great work.
A general question. In sizing the PSU there seem to be two things important: efficient range and transients. In ATX 2.x there seems to be some rules that you want a lot of headroom in the power (factor 2x) due the transients. However, ATX3.0 has that support build in. Does this mean you can “tier down” in power? E.g. having a 500W max usage gaming system, would it make sense to see a 850W ATX3.0 equivalent to a 1000W ATX2.x PSU? Since the 850 can peak to 1600W by design.
All this apart from noise, which is separate all together.
The same rules in PSU capacity apply between ATX v2.x and V3.x because every PSU has its peak efficiency at 40-50% of its max rated capacity.
So if you want the highest possible efficiency, if your system typically consumes 500W (DC), you should get a 850W or ideally a 1000W PSU.
Thanks. Appreciate it!
I got a NXZT C1200 and the coil whine is bad when idle. I have a 7800x3d paired with a b650 aorus elite ax and a 7900XT. I took the gpu out and it’s still there. Any ideas? I’ve read a few others having this issue.
coil whine is annoying, but is not considered an issue. still u can contact the store and see if u can do sth bout it.
Hello, I’m choosing beetween seasonic atx 3.0 PX-1600 and Seasonic atx 3.0 TX-1300, because price is the same and TX-1600 is above my budget. I’m looking for the most silent option. I wonder maybe if PX-1600 will work about 50% of it max for 800W will it be quiter than TX-1300 working same 800W?
And what about a pair of 2x 8pins for possible 12V-2×6 connection does these new Seasonic ATX 3.0 PSU’s have this option.
My setup is 7950x, and 4090 Strix OC.
Would be glad to see your opinion because seems like many of Seasonic buyers wonder about 12V-2×6 compability.
Thanks.
I haven’t tested the 1300W unit, so I cannot answer to your first question, sorry. Thing is that the PSU’s efficiency is at its highest at 40-50%, where thermal loads will be lower. If you want silence during gaming, you should be close to the PSU’s half capacity with your system at “game” load.
2x 8 pins can be used for a 12V-2×6 cable, yes.
This is by far the most comprehensive breakdown & reviews of PSUs I’ve seen. I’ve come back to your site and this article multiple times to make informed decisions / purchases. Thank you for all your content.
I’m doing a build with a 4090 and I’m looking for an 1000w ATX 3.0 PSU. I’ve noticed many of them don’t offer a 12vhpwr output, and instead opt for a dual 8 pin connection on the PSU, with the other end of the cable terminated with a 12vhpwr connector.
Is there any benefit in running a PSU that offers a 12vhpwr output? Or are the dual 8 pin to 12vhpwr PSUs just as good / safe?
If I understand your question well, dual 8-pin are good/safe. For more info u can visit jongerrow site (jonnyguru) who explains things in depth and in a comprehensive way.
Thank you for your response. I will check out jon’s site.
Is there any benefit to running a PSU w/ a dedicated 12vhpwr out, vs a PSU w/ the dual 8 pin connectors?
Given the amount of incidents of with 12vhpwr connector melting, and considering there is already a revision from psi sig in the works, would it be smarter to use a PSU w/ a dual 8 pin output? Basically, the fewer 12vhpwr connectors I’m using, the better?
Geia sou aderfe!
I am after making a new system at the moment. Sadly I am without a pc at the moment, otherwise I would wait for the melt-y cable fiasco to get resolved. But I have no system at all at the moment, and I really need to do some uni work.
My build list
13900k // With Thermal Grizzly Frame
Z790 Aorus Xtreme
G.Skill ddr5 7200/CL34
Corsair H170i Capellix XT
Corsair 7000D or BeQuiet DarkBase 900 (I cannot find the rev 2 anymore at a reasonable price)
3 x nvme m2.
I will also make use of 7/8 usb slots and the thunderbolt 4 of my motherboard.
GPU wise I am between an rtx4070ti and an rtx4080 (Probably a Suprim X or a strix OC model)
As I had BeQuiet PSUs in the past and I was nothing but extremely happy with them I have been leaning towards a
Dark Power Pro 13 1300W for a while now.
I have a good relationship with the BeQuiet guys to the point they inform me months ahead of new products etc. But I had no word regarding any changes on their current PSUs at the GPU socket.
I am really lost at the moment regarding this and I am halting building this system since mid May, to the point I missed an exam which I have to resit in September. I am one of those unlucky people that really need a system right now and they cannot wait any further for newer releases (aka 14900k or changes on GPUs and CPUs).
What is your advise oh sage one?

Your PSU reviews are otherworldly. How have I not come across this site before? You understand what you are writing about, deeply. This shouldn’t be notable, especially for a dedicated hardware site, but it is uncommon at best.
Thank you!
Hi Aris,
I am currently building a pc with 7950x3d and rtx 4090. I already purchased the Corsair rm1000x (2021) 80+ Gold, but have been reading up on PSUs and can still return it. Should I stick with 1000W or go for something higher? Which PSUs would you recommend in both cases? Thanks.
If you don’t face any issues, sudden restarts etc. there is no need to return it. It is a great PSU.
Should I care about ATX 3.0 compliance? And how would you rank between RM1000x (2021), RM1000x Shift, and Super Flower Leadex VII Gold 1000w? Thanks again.
You should yes. SF and then the Shift.
Thanks a lot!
Hi Aris,
Im running a OC gaming 4090 with 7800X3D, trying to decide on the best approach for a power supply. I’ve had two bad experiences with HX Corsair psu’s recently, one made popping noises and the other coil whine. which would be your pick from the following?
FSP Hydro PTM PRO ATX 3.0 80 Plus Platinum 1200W
Seasonic Vertex ATX 3.0 80 Plus Gold 1200W
Super Flower Leadex VII Gold 1300W
seasonic prime platinum 1300w (non atx3.0)
Thanks
Hi! If you can find the SF Leadex VII Gold, go for it.
Hi Aris, I recently bought FSP Hydro PTM Pro 1200W (PCIe 5.0 version), and it comes with two EPS cables, one rated 16 AWG, and another one with two connectors rated 18 AWG. Do you think it’ll be problematic if I were to use all three connectors on a Xeon w-3400? The CPU I’m looking to use can consume up to 600W (the board has three EPS connectors). Or is it better if I were to use PCIe to EPS adapter? Thank you!
To be frank I don’t approve piggy-tail EPS connectors. Each EPS on its own doesn’t have a problem at up to 384W, with 8A per pin, so you won’t have a problem most likely.
I think I’ll go with an adapter approach then. Thank you!
Some of the Amazon links are broken. In particular the fsp ti 1000w
Hi Aris,
So I have read and saw your video regarding the upcoming 12V 6*2 connector, I am buying a new computer consists of:
Cpu-13900k
Memory- G. Skill 64gb 6400 32-39-39-102.
Mainboard-GB Z790 Aorous Master
Graphics-MSI Suprim X 4090
SSD-990pro 2tb and sn850x 4tb
Cooler- Kraken Elite RGB
Computer is running 24/7 and used mainly for 4k video rendering.
I am contemplating regarding the PSU.silence ,performance, and efficiency are all extremely important for me.
I have 3 in mind:
1. Should I aim for the older gen overkill yet best and silent performer in the CorsairAX1600i which obviously can work with the new connector ?
2. second option -the new Seasonic Prime TX ATX 3.0 1300w version ? with this option there are 2 concerns ,coil whine, and some reports with former generation prime TX 1600 (the non ATX 3.0 version)had power recurring shutdowns that other brand did not have on the same system.
3. The new Be Quiet 1300w Dark Power Pro ATX 3.0 -which you have not reviewed, yet its your own recommendation from above for avoiding coil whine because of its silent wings, and would also be no slouch in efficiency and performance ?
Efcharisto! for your help.
I would go for the Seasonic PSU, because the Corsair AX1600i is not ATX v3.0 ready by design.
Hi Aris, I saw the Straight Power 12 ATX 3.0 PSUs pop up at mindfactory in Germany, so those seem to be released now – any info on when a review will be out for them?
be quiet! didn’t send me any samples of them so far, so no review on the horizon, sorry..
Hi Aris, have you heard something about the Be quiet Pure Power 12 M 750w? I’ve seen only 850w and 1000w have cybenetics report.
Are there usually many changes between models in the same psu line, or should we expect just a little less overall performance like in other brands? It’s quite cheap here in the EU, by almost 40€ vs other 750w psus by Corsair or Thermaltake with also 10 year warranty.
Thanks!
Hi! Normally its performance should be close to the 850W model. be quiet! sends review sample but no certification ones, unfortunately.
Thanks for the help Aris! Also, I’ve seen it’s a dual rail model, should I care about that if I am going to use a power hungry GPU or nowadays Single/Dual Rail don’t matter? Thanks!
Hi,
i just bought a ASUS ROG-Strix-Gold Aura Edition 850W (running @230v here in Europe) and had sent it back because of coil whine. The coil whine was only noticeable in idle – when putting load on the system it was completely silent.
Rest of (ooold) system:
i5-4670k@4,3Ghz
32GB DDR3
MSI Z87-43 Gaming
Palit GTX 1070
My old psu (Noiseblocker 530w from 2003!!) still works, no coil whine, no sound from fan. But i dont want to put more load with my planned system (7800x3d+RTX 4080) on it.
Any advice for silent psu without coil whine?
I am afraid that coil whine can be a problem in almost all modern PSUs under some conditions, because of the LLC resonant converter that they use. It is also the combination of hardware, the other system parts, that can lead to coil whine. Give it a go with be quiet! units which usually make sure to eliminate such problems. Corsair units are also good in this section, usually.
But Super Flower Leadex Titanium 1600W is not an atx3.x
This one it is. Super Flower messed the names between new and old units.
Hi, I am picking PSU for my rtx 4090, choosing between NZXT c1200w and Thermaltake GF3 1200w. As I red it uses same platform – CSZ, but parts used for example capacitors seems to may have some meaningful differences.
About +12V MOSFETs
NZXT c1200w use:
# 10x Infineon BSC014N06NS (60V, 152A @ 100°C, Rds(on): 1.45mOhm)
and Thermaltake GF3 1200w use:
# 8x Infineon BSC010N04LS (40V, 178A @ 100°C, Rds(on): 1mOhm)
Could you explain difference between these MOSFETs, which configuration is better built, does Voltage (40 vs 60) matter?
And generally looking only from part analysis perspective (primarily on 12V rail) which one is better built? uses better capacitors, etc.
Thanks for answer in advance!
The platform is the same, but NZXT did some changes for a bit higher performance, which seemed to pay off. If the price difference is high, go with the more affordable unit.
In FETs, more is better, but the RDS on plays a huge role in efficiency. The lower the better.
Hi, I’m looking for a PSU for a system with a 13600k and a 4090. I’m having trouble deciding between the Msi mpg a1000g pcie5 and the Corsair Rm1000x shift. At the moment I’m leaning towards the msi PSU as it’s around $40 cheaper for me but I noticed it still hasn’t been tested for atx 3.0 certification. Would you suggest I go for the Corsair or Msi PSU?
Thank you!
I personally suggest RMX Shift. I have it on my new Build and it is ok. It is tested and approved. You should only check if your Case is compatible, but most decent Cases won’t have a problem. I mean you have a 4090, you can’t have a bad case. 🙂
I am looking for your advice on a new PSU or even if I need a new PSU. I have an EVGA G2 Supernova bought in 2015, which is close to 10 years old. I will upgrade to a 7900 XTX or 4090 from a 1080Ti; it will be one of these two. I am leaning towards the 7900 XTX at the moment.
The rest of my system:

I am in the UK, and I have been looking at the major retailers and cross-referencing your best PSU for 2023 and the best ATX 3.0 PSU list to what I can find so far from your list I have found available in the UK the following:
Montech Titan gold 1200w
Montech Titan gold 1000w
DeepCool PX Series PX1200-G 1200Watt
MSI MEG Ai1300P PCIE5
MSI MEG Ai1000P PCIE5
Thermaltake Toughpower GF3 1200W
DeepCool PX Series PX1000-G
Seasonic Prime Ultra Platinum 1300W
ASUS ROG Strix 1000W
Corsair RM1000x (shift)
I want to keep my PSU for at least ten years, so I am looking for something with headroom for future upgrades and builds.
The Seasonic Prime Ultra Platinum 1300W is top-notch quality. The next best platform is the MSI MEG Ai1000P PCIE5, and then the rest from Montech, DeepCool, Thermaltake are based on the CWT CSZ platform. The Corsair Shift uses a unique platform, locked to Corsair, and is a good option, too, if you can utilize the side modular panel.
The prime ultra 1300 is now out of stock, MSI MEG Ai1000P PCIE5(£312.45), Seasonic Prime TX-1000(£339) and Seasonic PRIME PX 1600(£379) are in stock. Which would be the better buy?
Prime PX 1600!
Thanks appreciate the feedback
Just got a NZXT C1200, was between this and Hydro PTM Pro 1000.
Straightaway noticed coil whine. A lot of other reports of this from users online. Based on what I found out, it’s the always on 5V. It only happens on boot and shutdown.
Dunno whether to live with it or get a replacement. I appreciate coil whine can just be a noise. But doesn’t give me faith in the PSU quality.
It is weird because this specific platform, CWT CSZ is used in many PSUs without any problems so far and I have personally checked dozens of units.
Yo bro, would you offer Hydro PTM PRO ATX3.0(PCIe5.0) 1200W or MSI PSU MEG AI1300P for a system that has 4090, 7950x3d with mb msi x670e ace.
thank you
I would go for the FSP unit, because the overall performance of this MSI model is not impressive.
Hello crmaris,
I had a PSU related question that i am not sure fits here but i am very curious about your opinion on the matter. There have recently been an influx in reports on melting 4090 connectors again. Now some people are pointing to the GPU rail, FBVDD, PCIe and 16 voltages dipping below the 12v mark being indicators of melting. Would the resistances of the cables and voltage droop be any reason to be concerned?
I recently purchased the Asus Strix 1000w Aura and my voltages always seem to hover below 12v (11.9 to 11.7). I saw someone on reddit today who posted about this issue and said their voltages were dropping as low as 11.4 and less than an hour later they posted that their cable/connector had started melting.
I have not heard any prominent people talk about the voltages being any indicator and was wondering if you could comment on this from your perspective and expertise.
you can either post it here or even better in our discord server, where more people will see it. discord server: https://discord.gg/pv9rYXqm9w
Hello, thank you four your valuable work here.
I want to ask a question about Corsair brands. Their higher end models doesn’t support atx 3, but the lower RM tier does support it. How can it?
Is the reason of not being atx 3.0 not containing 12vhpwr cables? If not, wat prevents it to get atx 3 certificate?
If it is not explained, can you compare atx 3 requirment with its specs to answer my question please?
I have an article about ATX v3.0 already. Currently although some NVIDIA cards require 12VHPWR connectors, still they don’t need the extreme ATX v3.0 specs when it comes to power spikes.
But still next generation card might require handling the power spikes you mentioned.
What do you think i should buy to use my next 10 years ?
Hx1200i or Rmx 1200 ? or maybe Hx1500i ?
Is Rmx 1200 is more future proof?
Btw what i am buying for today is a ryzen system with x670e hero, ryzen 7800x3D and RTX 4090 Supreme.
Thank you for your valuable informations again

Hello, i am looking at an Atx 3.0 psu for my RTX 4090 but im interested in one Be quiet psu with pcie5 cable but i see that it has two psu rails one with 42A and other 46A and i wanna know is that safe to use on Rtx 4090 or i should look for more expansive single rail psu’s.
I am new to the psu so sorry and thank you very much for your assistence.
Greetings from Croatia.
Hi! Normally speaking, it should work because most 4090s don’t have high power spikes. Having said that, I would prefer a single 12V rail PSU for a demanding system, just to avoid any headaches.
Hey thank you for doing those comparisons !
Can you help me with this please?
I have Seasonic PRIME TX 1000, is going to an ATX 3.0 preferable or is it better to keep my TX 1000 and just buy the seasonic 12vhpwr cable ?
I can’t find if my PSU can meet the new transient response requirements.
It doesn’t but for the moment they are not required. Just buy a 12VHPWR cable and for the current cards it will be ok.
Dear crmaris
I am using Seasonic GX-750 and it seems that it has difficulties to cope with my Sapphire Pulse RX 7900 XTX at max load. My PC will just suddenly shut off at times when playing Control Ultimate Edition. Which (850W?) PSU will you recommend me? Thanks!
My PC specs:
Case: Lian Li O11 Dynamic XL
CPU: AMD Ryzen R9 5950X
GPU: Sapphire Pulse RX 7900 XTX
Mobo: Gigabyte X570 Aorus Master
AIO: Arctic Liquid Freezer II 360
RAM: Crucial Ballistix 3600 MHz DDR4 64GB Kit
Fans: 4 x Noctua NF-S12A
SSD: Samsung 980 Pro 2TB (NVMe), Plextor PX-512S3C (SATA), SK Hynix SC313 (SATA)
HDD: 4 (1TB , 2TB, 3TB and 6TB)
Yes what you describe is because of the PSU. You need at least 1000W for your system, to be on the safe side.
Hello, i see that Be quiet 12M i popular among atx 3.0 psu.
Should i choose Be quiet 12M at 200 euros
Or corsair Shift 1000w for 270 euros
For my RTX 4090 gaming oc
Thank you.
Corsair is expensive, because it uses better parts. If you don’t care and you won’t use the side panel of the Shift, go with the be quiet unit.
[FIXED] —> Guys that built my computer didn’t plug in my CORSAIR Link™ USB Cable 🙄
I connected it now and iCUE immediately recognized my PSU and I was able to set it to Single-rail
Hey man
So, I finally bought Ax1600i and wanted to make it Single-rail like you told me, but iCUE sensors don’t detect my Ax1600i PSU, so I can’t access it…
I tried HwInfo64 and I can’t see my PSU there as well…
This is what I have under Universal Serial Bus (if it may help you in any way, I don’t understand any of that unfortunately): https://prnt.sc/xclKtzu7B2iU
Do you have any advice for me?
Is there any other program that can let me change my PSU into Single-rail?
You should talk to Corsair’s support about that, because normally iCUE should see your system.
Hello, will you do Be quiet pure power 12M psu? Its priced at 200 euros .
Thanks.
Hi! I have reviewed one already and I plan on doing more!
Since FSP Hydro Ti Pro 1000W is not available and my options became a bit more limited, which one of these two would you recommend :
MSI MPG A1000G PCIE5 1000W ATX 3.0 vs Thermaltake ToughPower GF3 1000W ATX 3.0 ?
Which ever you can find at a better price, both are good units.
Is the FSP Hydro Ti Pro 850W as convincing against the competition in the 850W class as it is in the 1000W class? Or are there other PSUs that are a bit better in terms of overall performance?
Haven’t tested it yet, sorry. Will ask from FSP to send me one.
No problem. I hope or rather assume that it does not perform much worse. I could get hold of one for 225€ and had to grab it.
But I’m still looking forward to your test!
THX for your great work
FSP Hydro Ti Pro 1000W was briefly in EU stock for some 260€ and now they’re gone.
That one is a bit expensive but might be the best option overall.
Which ATX3.0 would you recommend for 13600K and RTX4080 build to be excellent for at least 5 years? Thanks so much!
I would go for a good 850W unit, or a 1000W to have more headroom. Thermaltake GF3 1000, Montech Titan Gold 1000, Corsair Shift 1000, Seasonic Vertex – 1000
There is quite a price difference between 850W and 1000W ATX3.0 PSU’s and to be honest, I do not know what will I get with 1000W considering 13600K and a possible undervolting with RTX4080 with basically not much OC headroom.
Which 850W one would you recommend? be quiet! Dark Power 13 or something else?
RM850x Shift, Thermaltake GF3 850 are also good options.
FSP Hydro Ti Pro 1000W was briefly in EU stock for some 260€ and now they’re gone.
That one is a bit expensive but might be the best option overall
I would say the opposite. Good price!
