Hey, may I please ask, why is there no actual review of the Leadex VII 850 XG?
Thank you.
Indeed. Will see what I can do about that.
You mentioned that you added Deepcool PL750D to the best ATX 3.0 PSUs list. But I cant find it anywhere. So is the PL750D worth buying? Will it be reliable?
Hey, just wondering if the Leadex titanium 1600w ATX 3.1 would perform the same as the Leadex titanium 1600w ?
trying to decide for a threadripper 7960x and dual 3090s, Not sure if I should go for the 3.1 version since there are not much reviews yet on the 3.1 variant. Thanks!
Hello i’ve been planning to grab the Super Flower LEADEX VII Platinum PRO 1200W ATX 3.1 for my next build but i can’t find it anywhere in the US.
Coole Master MWE Gold 650 V2 Full Modular it is good PSU?
Great article. I believe the original season tx 1600 wasn’t fully atx 3.0 compliant and had some like of limitation to 1000w. Does the noctua edition have this issue?
Hi, my vertex gx-1200w jjust died (luckily without damaging my system) and i have to replace it.
Should you go for another seasonic 1200w or maybe for a super flower leadex vii pro 1200w?
Or any other suggestion will be pleased 🙂
I use Vertex GX-1200 on all of my test systems without any issues. You should give Seasonic one more chance I think 🙂
Yes, i was more for seasonic then super flower, i will follow your advice. One unfortunately device can happen to everyone.
Thanks a lot for your answer
Hello sir, which 750w would you recommend to buy in Amazon? Im trying not to get too fancy or expensive since I’ll be running it with a R5 5600 and a rx 7800 xt. Thanks in advance.
I saw NZXT C850 in some rankings. Is that 2022 ?
yes
Hi Aris,
I saw the report on Cybenetics Super Flower III 1300W (ATXv3.1) where you mentioned the unit Broke in 5VSB OCP testing. Is this something to be concerned about if I were to buy this unit for ATX 3.1?
Thank you.
It doesn’t concern you if you don’t push 5VSB too high. That said, from now on, we decided we won’t provide an ATX v3.1 pass to any unit that breaks during the evaluation of protection features.
First of all, thank you very much for this detailed review.
Can you give me a hint what would be the best pick for a Ryzen 78003DX and a 7900XTX?
So far I’m wavering between the Super Flower Leadex VII XG 850W, Super Flower Leadex VII PRO 850W or the Asus Rog-Strix-850G-Aura-Gaming.
But I’ve also seen that you often recommend the Corsair RM850x.
Thanks for your advice!
I’m so glad that I found this website a few weeks back as I was researching for my first computer build.
Thank you thank you thank you for putting the time and effort into something like this. It’s by far the best resource I’ve seen for PSU’s on the internet.
One suggestion: For the list of best power supplies, maybe you can include a way to filter them by price, or add a ranking by price too? Obviously, it makes sense to put them into tables by wattage like you already have, but I think you would gain even more traffic to this article if people could use it to help find the answer for “best 850w PSU under 100, under 150, under 200”, etc (just example price ranges)
Lastly, one question: I’m looking for an atx 3.1 850W power supply between 100-150 dollars. I’ve mostly narrowed it down to the new RM850x or the NZXT C850. Which one is a better option? Or should I consider something else?
Thank you so much!
We will try to work on something for the best PSUs; thank you for the suggestion! However, prices are not that easy to follow since they constantly change.
Both are great, personally I would go for the RM850x
Thank you, very much appreciate the reply!
I agree tracking prices can be tough, maybe to start it could be based on MSRP..
I was leaning towards the RM850x, thank you for confirming!
Hi, I’m thinking of getting Lian Li Edge 1000w for my r9 9900x and 4070 ti super and haf 700 case. Im not sure if the asus strix wont be a better choice but I do like usb hub and cables included with Lian Li. I do understand that it is included in the best table but do you recommend Edge 1000w?
I have data for it from Cybenetics, but I haven’t reviewed it and won’t so cannot advice about it.
Hi, I have a Segotep Gw750, and a Sama black power 850w . Should I keep the Sama and return the Segotep. I can’t find much on Sama.
I wouldn’t trust the SAMA PSU.
I’m looking at buying the FSP hydro ti 1000w 3.0
Now that they have updated it to have a 12v-2×6 connector on the psu side, does this make it a ATX 3.1 psu?
Does it have the sense0 and sense1 pins for open to open 0 watts?
Hello, which one would you prefer between Corsair RM850x ATX v3.1 and Asus Rog-Strix-850G-Aura-Gaming? Thank you for all the amazing work you’ve done.
Corsair RM850x
Thank you!
Hi Aris,
I know the Corsair RM850x (2021) is not on the charts as it’s not really an ATX 3.x unit but where would it roughly go with the Corsair 12vhwpr adapter? Based on the Pure Power 12M review would it go above it maybe around the Vertex/Shift %?
Thanks!
Where can I read Lian Li Edge review?
I didn’t review it, sorry.
Hello, I apologize for asking so many questions lately.When I found the hx1500i for a very reasonable price, I bought it thinking it was a good deal, but I’m confused about one thing.You said that this power supply does not meet the requirements of ATX 3.0. Should I return it? (I paid $220, everything included)
No worries. Check with Corsair. I think they must have a 12VHPWR (or 12V-2×6) cable for it, taking power from 2x 8pins. If you get that, no need to worry. No GPU so far has high enough spikes to push a PSU like that to its limits.
Of course but I don’t think the lack of ATX 3.0 is a reason to return it. Yes, I also bought an original Corsair cable Do you think I should return it?
If it covers your needs, why return it? You bought it at a good price.
Yes but I wanted real 3.1 support. But I guess I won’t find it for a long time. Thanks for all your answers and help.What motivated me to return it was reading on reddit that multiple people were having issues with the 4090 and hx1500i crashing and freezing.
Thank you for this detailed review. Asus Rog-Strix-750G-Aura-Gaming is an atx 3.0 or 3.1 I still can’t understand sorry. I know that atx 3.0 standards are harder but what i want to know is whether asus rog aura uses 2×6 or 12vhpwr? thank you in advance for the answer.
the only difference between ATX v3.0 and v3.1 is on the PSU’s connector on its modular panel, and the hold-up time. If a PSU has 12VHPWR an meets all other requirements, it is ATX v3.0. If the SAME PSU has 12V-2×6 connector, it is also ATX v3.1 compliant.
Thanks for the answer. I know that but I am looking for a real 3.1 psu for the safety factor and corsair rmx atx 3.1 is not yet available in my country. So Even though the price of this product is affordable in my country, I pass on it.
Although it was stated as 12VHPWR in the review, I was curious if they were using the current pin since Intel had issued a 3.1 certification.
Hey Aris.
The MSI MEG is duplicated in multiple graphs with different results. Which one should we considerate?
Thank you for your amazing work
Hi! We tested both samples and by mistake I included both. Will fix it when possible. Thank you for letting me know!
