12VHPWR ATX3.0 PCI-E 5.0 Power Modular Adapter 600W will be enough for RTX 5090?

ATX 3.0 vs ATX 3.1: What's the Difference?​

It doesn't say it's a "higher standard" lol.

ATX 3.1 features a shorter hold-up time of 12ms, compared to ATX 3.0's 17ms hold-up time. This results in a small improvement in the PSU's efficiency.
...the new 12V-2x6 connector is designed with longer conductor terminals (12V and ground) for improved conductivity, as well as shorter sense pins.
The shorter sense pins allow your GPU to now shut off if the connection comes loose.
In summary, ATX 3.1 delivers some key improvements as compared to it's predecessor. They might seem minor, but it's a better standard now.

So it's better for sure lol

The new connector is better than the older one which frankly never should've seen the light of day. In terms of specs, ATX 3.0 very slightly edges out ATX V3.1 but it literally doesn't matter as most decent PSU's have a hold up time much higher than the ATX spec anyway.

Where did you see that? That wouldn't make any sense to do that...

looks like you are the one having reading issues as that was posted above in a link and stated by me. Once again, learn some facts and then come back to post so you stop embarrassing yourself.

"ATX v3.1 PSUs are NOT ATX v3.0 compliant because of the lower hold-up time. This is a first for the ATX spec! A newer spec does not cover the previous one in all aspects!"

I can see what kind of tdps gpus are via bios information, but i cant see any on something not out yet

Sorta like complaining about a price that hasn't been set?

ATX revision is inconsequential, 1000 W single-rail PSU is enough, already confirmed. TGP is 575 W. Quality supply like EVGA 1000 G2/P2/T2 series, Super Flower Leadex or Seasonic Prime/Vertex will do great.

no mention of of single or dual (or even single split) but all modern PSU are single usually up to around 1200w when you start to see some real dual rail units

RTX 5090 System Requirements​

• PCIE 4.0 X 16 slot (For best performance)
• 1000W Power supply or greater.
• PSU with a native 12v-2x6 connection OR a 2 free 8-pin PCIe connections and the required cable.

Sharing a recently purchased EDGE PSU ATX 3.1
This is the new 12VHPWR connector from Lian-Li. Yours may be different and more expensive.

Official site says:
4x PCIe 8-pin cables (adapter in box) OR
1x 600 W PCIe Gen 5 cable
Seems be OK!

4 free 8-pin PCI-E connections with PCI-E slot 75W can deliver max 675W power.

Interesting how 2 ms peak power with NO OC RTX 5090 models, need reviews?

4 free 8-pin PCI-E connections

Good catch, I took it off the corsair site and clearly poorly worded by them. With heavy gauge wire you can have a 300w 8-pin port which I assume is their statement. In fact you can be ATX 3.1 complaint with two 8-pin 300w headers as "ATX v3.1 spec, clearly stating that the 12V-2×6 PCB header is optional for modular PSUs!". You can see examples of that in the link posted.

It should be better worded by Corsair as not to confuse people who have 150w 8-pin PCI-E connections in their PSU

posting so people have a better understanding of ATX 3.0 vs ATX 3.1 in terms of what's on paper for the spec not specific PSU. Like I stated before, get the better performing PSU regardless of ATX
3.0 or 3.1
via HB (link already posted in the thread)

• Changing an ATX v3.0 PSU to an ATX v3.1 one only involves changing the 12+4 pin header to the new one (given that the PSU already has one).
• If a PSU uses 2x 8pin headers on its modular board to power the 12VHPWR (or 12V-2×6) cable, it is automatically ATX v3.1 compliant (provided it follows the rest of the requirements).
• PSUs with native 12VHPWR (or 12V-2×6) cables can be ATX v3.1 compliant if they already meet the ATX v3.0 spec.
• ATX v3.1 PSUs allow for a lower hold-up time (12ms instead of 17ms in ATX v3.0), which, in my opinion, is a big step backward!
• ATX v3.1 PSUs are NOT ATX v3.0 compliant because of the lower hold-up time. This is a first for the ATX spec! A newer spec does not cover the previous one in all aspects!
• There can be ATX v3.1 PSUs WITHOUT the 12V-2×6 connector, which have lower transient response requirements (150% peak instead of 200%).

In regards to shorter hold up time according to the 3.1 spec - spec says one thing, actual tests of PSU shows something else:

Cybenetics Test - Montech Titan PLA 1200W White

Cybenetics Test

www.cybenetics.com

Meanwhile if you compare just the 3.1 vs 3.0 specs:

ATX 3.1 features a shorter hold-up time of 12ms, compared to ATX 3.0's 17ms hold-up time.

 

[dirtyferret]

Meanwhile if you compare just the 3.1 vs 3.0 specs:

One is a paper spec and the other is real world PSU review. People should get the best performing PSU regardless of ATX 3.0 or 3.1 but that doesn't mean a newer ATX PSU spec did not cover an older one on paper.

17ns or

My PSU has a 24ms Hold-up time but 24, 17 or 13ns isn't going to make any difference if your power shuts down anyway... I'd be more worried about having a PSU not being reliable!

excellent, individual units were never brought up just the paper spec

but 24, 17 or 13ns isn't going to make any difference if your power shuts down anyway..

it will if you have a bad UPS transition time or the hold up time is below the UPS transition time and you kind of need that PC up and running in certain demanding field like medical

I'd be more worried about having a PSU not being reliable!

OK, no one has brought that up or said otherwise. I already stated get the best PSU regardless of ATX 3.0 or 3.1

Well as much as I agree, Hospitals are a different breed. We're mostly Gamers here... Medical, Army, Datacenters, etc. are a different world lol. Also I'm pretty sure they buy some specific PSUs not consumer grade PSUs.

Fair enough. I just wish they made those connectors safer. Nvidia tried to rush them out ASAP but most people were happy with the 8-pin connectors/cables, even though it was going to change sooner or later.
