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.

Hey, quick question. Do you know if NZXT C850 V2 850W is as good as V1?
You mean the ATX v3.1 version? It is good yes.
If you had to choose between the ASUS ROG Strix 1000G Aura Edition (with 12VHPWR connector sadly, so still ATX 3.0) or the Seasonic Vertex PX-1000 (now ATX 3.1 compliant), which one would you go for?
The Vertex most likely.
Even with your concerns regarding the protection features of the vertex?
Please review phanteks amp gh 1000w platinum
hello i cant seem to find the review for segotep gm750/850 or is my browser bugged
i currently on the fence on taking it but i can get it for 22usd less
I’m happy to see the PSU I bought for my new PC, the NZXT C1000 Gold, lead the overall performance chart for 230V. But I don’t understand how it can have a better overall performance than the FSP Hydro Ti Pro 1000W when the FSP crushes the NZXT in almost every other chart. I did go through the Cybenetics PSU Test Protocol to understand more about the overall performance calculation; the only thing left is to follow through the calculations myself. I only went for the NZXT because it was much cheaper.
Thanks for the thorough testing 🙂
Feel free to do the calculations. We always need some extra checking!
Hi, can’t decide between Deepcool PX1000G and MSI MPG A1000G. Which one would you choose?
Hello. I’m in need to upgrade the PSU of my PC and I looked a lot on this site and in others, but there is so much good looking options that I cannot choose one. I’m looking for 850W PSU under 160 bucks. So there are my options for now with prices below from lowest to highest, if someone would help me I would be glad:
-Cooler Master MWE GOLD V2(123$)
-FSP/Fortron VITA GM 850W(131$)
-NZXT C850 V2(144$)
-Thermaltake Toughpower GF 850W(144$)
-MSI MPG A850G(154$)
-XPG Core Reactor II 850W(157$)
I do not require high level of silence, just not something completely over the top. It will power Ryzen5 7600 and 7800XT for now. Also RMx Shift and Super Flowers here are much more expensive, like 200 bucks.
Hi i have a question. I asked on reddit and discord on different places but nobody answers or helps with this.
Hydro K PRO ATX3.0(PCIe5.0) 750W or XPG Kyber ATX3.1 750W which is better? I have no other choice because these are the only options for the prebuilt PC that I’m gonna buy. XPG Kyber seem to have better specs on paper but i don’t know if it’s really better. I don’t care about noise, I want it to be reliable and durable.
Some details: First of all i live in Turkey. FSP PSU comes with FSP CMT318 PC case, XPG Kyber comes with XPG K Mesh case. I can’t find individual pricing for XPG PSU but with case + psu it’s $126 on the internet, FSP case + psu is $164. Both PSU + case sold at the same price on the website that I’m buying my prebuilt PC. My overall profit decreases when i choose XPG case + psu.
I forgot to tell my CPU and GPU. Ryzen 5 7600 and Inno3d RTX 4070 super twin
Hi, Im new to PSU’s Ratings and all, but i came across 2 PSU that i wanted to buy. It’s either Super Flower Leadex VII Platinum PRO 1000W – SF-1000F14XP (Im too confused to pick which model on the SF Leadex Lineup) or the MONTECH TITAN GOLD 1000W 80+ GOLD.
Are they good? Im planning to use them for a 4080S and 7950x3d. And maybe dual gpu config in the future (If you have any suggestions on more watts PSU models, i would be happy)
Thanks!
I would go for the Super Flower unit. It can support your hardware yes, but for dual GPU you should better go for a 1500-1600W unit. Super Flower 1600W Titanium, or Seasonic Prime PX-1600. Or Corsair HX1500i
Hey, I’m relatively new to the whole PSU thing and was wondering if the XPG Core Reactor II 1000W would be the best choice overall for the $100-$150 price range. Thanks for the reviews it’s definitely helping me understand PSUs more!
It is a very good PSU yes.
On page 6 “>1250W PSUs” the power supply XPG Cybercore II 1300 is included in the table “Best Three PSUs”, but not in the graphs below.
Thanks! I will look at that!
Hey,
Super Flower Leadex VII XG 850W or pro version or Cooler Master GX III 850 or Montech Titan Gold. Which one would you choose?
Super Flower
Gold or pro version?
Gold.
Any plan on reviewing the Thermaltake Toughpower SFX 1000W 80Plus Platinum? It seems that now it is a true SFX instead of SFX L.
No relations at all with Thermaltake this period.
I’m planning to buy the “1st Player NGDP 1000W” (HA-1000BA4) for €112 plus VAT and delivery.
1st Player NGDP 1000W has an overall performance of 98.15% (230V) in your charts. This makes it one of the best 1000W PSUs, right?
My question is: Why is it so cheap? Is there something that I should worry about?
I discovered that your review of “1st Player NGDP 1000W” is for the HA-1000BA3 model, which is “Platinum” and costs €133.
The “Gold” rated HA-1000BA4 is likely not the same PSU. So I’m going with the HA-1000BA3 (Platinum).
Hi
between this power supplies which one do you recommend?
SilverStone HELA 1300R Platinum
FSP Hydro PTM X PRO 1200W
FSP Hydro PTM PRO 1200W ATX 3.0
Asus ROG STRIX 1200W Gold Aura Edition
Corsair RM1200x Shift
Thanks a lot for your help and greatly appreciate your work!
FSP units are very good for transient response, which matters the most in today’s systems. If you want the lowest possible noise output, use the Asus unit. If you can exploit the side modular panel, the Corsair unit.
Thank you for quick response
Is there a difference between FSP Hydro PTM X PRO 1200W & FSP Hydro PTM PRO 1200W ?
which one do you recommend?
Awesome content thanks for this extensive testing.
Quick question, I need a 1600w psu for 2 x 3090, should I go with the PX-1600W or wait for their new model ? any update on the release date ?
Thanks
No need to wait, go for the PX-1600 if you need it 🙂
Hi!
Since they are around the same price, which would you go for?
NZXT C1000 Gold ATX 3.1 or the Thermaltake Toughpower PF3 1050W Platinum? From what I can tell the main difference is that the NZXT is ATX 3.1, but only Cybenetics Gold, whereas the Thermaltake is ATX 3.0 but Cybenetics Platinum. I don’t really care about the noise rating difference to be frank.
Thanks 🙂
NZXT
Thank you 🙂
Moin Aris,
was hälts Du von den Netzteilen ASUS ROG Strix-850G Gold Aura Edition bzw. ASUS ROG Strix-1000G Gold Aura Edition, ich brauchte nur ein 850W Netzteil würde jedoch für das 1000W Netzteil nur 5 € mehr bezahlen. Über eine kurze Antwort würde ich mich freuen.
Danke Frank
for me, if it is only 5 euros more for the 1000W model, it is a one-way road! Go for the 1000W model!
hi maris, why don’t you include ax1600i in the 1250w up list. love to see high end battle between tx1600 vs ax1600i.
because it isn’t ATX v3.x 🙁
Nice to see such an extensive review done on ATX3.0/3.1 PSUs.
Any chance for you to have a look into the Antec NE850/1000GM ATX3.0 certified units？
I don’t have any relations with Antec I am afraid.
Good morning
Can you review Corsair HX1500i ?
Thanks
Will ask for a new sample from Corsair. The ATX v3.1 version
hi please review ZALMAN teramax II 1200w
I agree mate. Point is , is PSU able to provide the new sense encodings to the graphics card,as part of atx 3.1? That’s the question I can’t take a direct answer
Hello Ari
I bought CORSAIR HX150Oi (cp-9020261-eu) which corsair advertises it as ATX 3.1 certified.The box that came though says atx 3.0.Corsair support via email told me that the 12VHPWR cable meets both 3.0 and 3.1 requirements.Shouldn’t though for the psu to be atx 3.1 also integrate-or support- the new sense pins, to support for example the zero watt scenario?Do you happen to know if the atx 3.0 version supports already the zero watt ?That would explain their claim of atx 3.1 certified ,even if the box says 3.0.I am asking this ,because 3.1 is not only about the cable,it must also comply with the new sense pins.Thank you
It is complied with both ATX3.1 and 3.0. The reason for not being mentioned as ATX3.1 is the packaging which costs to be replaced.
Just a quandary.How is possible this psu which is atx3.0 and produced for example july 2023 complies with atx 3.1 announced September 2023?About the cable I get it.About the sense pins though?Does the specific psu understands the new sense pins even if it’s produced before the announcement of atx 3.1?
The core difference of ATX3 vs 3.1 is that 3 is more strict (e.g., higher hold-up time requirement) than 3.1. So, if a PSU complies with ATX 3 it auto-complies and with 3.1. The cable remains the same.
Any opinion about the MSI MAG A750BN PCIe 5? I barely can find anything.
I haven’t tested it, sorry. Else it would be included in the charts.
I think you should condemn them，ha ha
nah won’t bother…
Hi，CRMARIS，I am china saw it ，https://pplp.info/#about，This website，I want to know about team have Infringement or not
ha ha they copied everything from Cybenetics….
At the same prices, which is better and do you recommend buying seasonic Vertex platinum px 1200 or leadex vii 1200 platinum or leadex vii 1300 gold ?
thank you.
Hey! Thanks for the list as others already have said as well!
I saw you reviewed the 1st player NDGP 1000w & 1300w which are both on the Helly EPS0100 platform and was wondering if there would be a chance for you to check out the Phanteks AMP GH 1000w/1200w which are also on the same platform?
Thanks!
Hey. Thanks for the list. I wonder that is Asus Rog Loki 1200W Atx3.0 or Atx3.1? On their web page it says Atx 3.1 compatible but on the box of the item it says Atx3.0. I’ve just bought one for 280$ and I’m not sure it’s worth it or not? I just wanted to buy best and compact psu for once. I didn’t need 1200w but I wanted it to be future proof. Thank you for your answer.
You don’t have to worry, in PSUs I can say that I prefer ATX v3.0 because the hold-up time is longer 🙂 I don’t remember the type of connector it has. You can check it easily if it has 12V-2×6 or 12VHWR. The sense pins are deep inside the socket in the first.
Hello!
First of all, I’d like to thank you for your reviews.
I’m building a new PC powered by 7800X3D and RTX 4080. Choosing the PSU has turned out to be quite challenging. My options are:
– 1STPLAYER NGDP 1000W (~$150 in my area)
– Montech Titan Gold 1000W (~$180)
– XPG Core Reactor II 1000 Gold (~$180)
– Deepcool PX1000G (~$180)
Deepcool PX1000P and Super Flower Leadex VII are more expensive ($220 and $200)
I might as well go for 850W with the respective models + be quiet Straight Power 12 ($165). What would be a better option and model?
Thanks!
What happened to the other comments?
I put them in pages, because they made terribly slow the page’s loading time.
So how to access them?
I will ask from them to send more review samples.
Hello, Any plans to review new CoolerMaster ATX 3.0 SFX psu?
This one specifically
https://www.amazon.com/Cooler-Master-90-Degree-Connector-MPY-8501-SFHAGV-3US/dp/B0CFCZYC2Q
In terms of efficiency and quality of the component base, which is better – Cooler Master V750i Gold Corsair or RM750x (Shift), subject to the same price
I would say equal in quality. For efficiency you can look at the provided graphs, in my article.
Trying to order a 90-degree 12vhpwr by 2x 8pin PCI-e cable to connect an Nvidia FE 4080 Super GPU and a Super Flower Leadex VII XG 850 PSU.
Cable mod makes a 90-degree cable that is compatible with a Super Flower Leadex III PSU. Are the 8pin PCI-e connectors on the Leadex VII pinned the same as on the Leadex III ?
as far as I know, it is different, the pin-out on the Leadex VII
Was looking on the Cybenetics PSU list for ATX 3.1 and stumbled upon a brand which I’ve never heard of: BoosBoxx. Any thoughts on their power supplies. In particular the PB1000P. Thanks !
Decent PSUs made by Great Wall is among the largest PSU OEMs.
Between the seasonic vertex platinum 1200W and super flower leadex vii 1300w, which would you go with? Primary concern is ripple and transients. Adding it to a 4090+7700x build
Would love the seasonic tx 1300W but it’s just too pricey, unless you think it’d be worth saving for. Currently have an evga 1000 g3 with the atx adapter to get me by.
Super Flower
FSP Hydro PTM X PRO 1200W or Super Flower Leadex VII XP PRO 1200W ?
Both are very good. It depends on the price you find them. Which wIll be more affordable.
Would love to see you check out the Antec NeoECO NE1000G M or NE1300G M. From what I can find they seem to be a Helly OEM design (according to johnnylucky’s PSU database), and the psu seem rather interesting. I’ve been tempted to pick one up, but have been unsure about it over the Seasonic Vertex GX-1000W considering it’s been on sale. They are around similar price points. If it is indeed a Helly design PSU, would it in theory perform similar to something like the NGDP 1000W? From what I could find, It has a FDB fan with no Ball bearings from Yate Loon. The cables are all 16awg except the sata, and Molex cables which are 18.
I will talk to Antec during Computex to continue our cooperation.
Awesome! Thanks always for all you do
They are very similar to each other，in especial is ABKO ULTIMATE GX850
ZHONGYUAN POWER GX850 is south korea(ABKO ULTIMATE GX850 and darkflash UPT 850W)or china thetmaltake GF1 850 ATX3.0
ZHONGYUAN POWER GX850
FSP’s line of PSUs seems to be about to get replaced if Amazon stock is any indicator. All models are starting to run low and prices have dropped.
Got a FSP Hydro Ti Pro for USD 255, that’s pretty good!
or they decided to drop their prices.
hello!
In Korea, many people understand that pcie 5.1 is a socket on the graphics card of the motherboard. But in the content, we are all talking about power cables. Can I use pcie 5.0 as it is for the motherboard?
Sorry, I cannot understand. PCIe 5.0 for the motherboard?
The Korean community says that PCie 5.0 on the motherboard changes to 5.1
So the motherboard of PCie 5.0 on sale becomes useless when it changes to 5.1.
But it seems to me that the motherboard has nothing to do with this issue and only needs to change the power.
Hello Aris!
I am upgrading my CPU and GPU to a Ryzen 5800x3d and an RX 7800XT respectively. Currently I have a Corsair Rm550x PSU from my previous build. Will it be enough if I am only using the pc for gaming at 1440p or is it time to upgrade the PSU too and if so what PSUs do you recommend?
It would be better to upgrade your PSU given these results: https://hwbusters.com/gpu/amd-radeon-rx-7800-xt-rx-7700-xt-performance-power-analysis-noise-output/28/
To be future-proof, I suggest a 750W unit. The cost difference with a similar-spec 650W is small. There are plenty of choices in 750W, with a quick look at the corresponding category in this article, you can find the one closer to your budget.
Hi Aris!
I have a Corsair Rm550x PSU back from 2018 that is currently powering a Ryzen 5 5600 and GTX 1060 GPU. I am looking at upgrading to an RTX 4070 Super or an RX 7900 GRE, and possibly upgrading the CPU also to a 5800x3d at a later date.
Do you think the Rm550x is still ok if I am only using the pc for gaming at 1440p, or is it time for an upgrade? If so, what PSUs would you reccomend?
Please review 1stplayer ngdp gold 850w
have it on the list!
Alright, thanx 👍
Hello Aris,
After checking out your articles about atx 3.x, I can’t help but feel a bit frustrated as I got a Prime PX1600 atx 3.0 PSU and need to get another 1200+ watts atx 3.x for my brother’s build.
It costs quite a penny and now I just feel like it will need to be upgraded for the next GPUs that will have the 12V-2×6 sockets. I’m just speculating, but by then the PSU maufacturers will update (AGAIN) their lineup to have that connector on their PSUs. Is there something I’m missing in order to circumvent that ? Or just change PSUs and sink another 800+ bucks in just a year for the two PCs?
Also, you mention that the change from 3.0 to 3.1, wont be beneficial unless you have both a 3.1 PSU and 3.1 gpu. I found this news regarding Seasonic releasing a “12v-2×6” cable: https://videocardz.com/newz/seasonic-reveals-its-new-12v-2×6-angled-power-invites-rtx-40-owners-to-test-it
Any opinion on it? Is it just some marketing stuff so that they dont update their PSU boards?
Thanks a lot for your help and greatly appreciate your work!
PS: I initially wanted to go with the cybercore II 1300w or the MSI AI1300P, but the XPG wasn’t available and the MSI’s 24pin would never click on the mobo (almost impossible to get it flush, almost broke the mobo pcb, and extremely hard to pull out, I had to use a flathead screwdriver to seperate it) so I returned it. Is it normal or I just had a faulty cable ?
The fact is that the PSU’s connector rarely creates issues, whether it is 12VHPWR or 12V-2×6. You won’t have any issues if you have the respective cable connected properly (all the way into the socket). The problem was mainly with the graphics cards. So, I wouldn’t worry much about the PSU.
Allright funky one : Why the PSU high end market doesn’t offer the possibility of managing the power supply of our screens and thus benefit a little more from their efficiency. with double or triple screens becoming usual and drawing more and more pixels this seems like a good idea? with few ports on the back next to the input and little plastic protection when not used and all good!
I’m also sad you don’t have any test of the FSP Hydro Ti Pro 850W but since i might wait for the atx3.1 and pci 5.1 i don’t care that much 🙂
Hi, i just don’t understand what the Overall Performance means in that subject ? Since Efficiency is already in there i don’t get it…
Overall performance takes into account ALL major aspects in a PSU, from load regulation and ripple, to efficiency and transient response.
Allright thanks
