12VHPWR ATX3.0 PCI-E 5.0 Power Modular Adapter 600W with PSU 1000W 80+ Platinum ATX 2.0 will be enough for RTX 5090 power?

 

[TommyT]

my best guess, we will know after the first review...

 

[dgianstefani]

Should be.

Wait

I'd wait and see what sort of power draw and transients this thing has. Rumor right now is a 575W TDP. But it's just that...rumor.

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

All the RTX 50s will come with the new connector (12V-2x6 aka ATX 3.1 & PCIe 3.1 Certification). So just for peace of mind I wouldn't buy a 3.0 PSU but a Certificed 3.1 instead

There's a reason why some connectors get on fire and some not... I was very scared when I bought my 4090. But I don’t want to take any risk with the 5090 that's why I bought an ATX 3.1/PCIe 5.1 PSU.

 

[N/A]

Play it safe with a certified PSU or just buy the cable that is sold separately from the same manufacturer. But if power supply sticks to 2.0, does it mean that it moves away from the 12V split into 2 or 4 rails, I can't remember. If it has some very exotic modular connector, or you don't trust the cable manufacturer, it's not worth the risk. There's no reason not to trust Seasonic. I have a Corsair so I'm very blinded by favorites and they claim the cable is the same, there's no difference, but does it apply to old batches. OP leaves questions unanswered like maker, rails, maker, age.

I believe the cable is the exact same. The difference is the pins within the connector on the card side (and maybe PSU side?).

Yes the cable hasn't changed but the connectors on the PSU are the most important because the melting are due to the pin sizes.

In this article, we will go over ATX 3.1 performance and features, and the unique benefits of Cooler Master’s own ATX 3.1 products.

Also the 3.1 PSUs have better regulation of the "Micro Tolerance Loads" within 1% whereas the original Intel certification was 5%.

it's the same connector, it's just the PCB header pin out is different. In fact several brands have already made the PCB change will selling their units under "ATX 3.0" to clear out inventory. Also, ATX 3.0 has a mode demanding hold up time to 3.1. So like many times, the consumer is better off getting the better product (be it 3.0 or 3.1) as opposed to necessarily the newer one.

PSU side

PSU are the most important because the melting are due to the pin sizes.

melting were mostly on the graphic side, PSU issues were due to not fully inserting the cable to the PSU

Well that's your POV, but I wouldn't risk burning a GPU that is going to cost me $2000...
Also I'm pretty sure that if some connectors melt again, NVIDIA & AIBs will definitely blame you and tell you they do not accept refunds unless you have a 3.1 Certificed PSU... All those companies are too shady nowadays, so I wouldn't trust any of them. That's why I bought a TX-1600 Noctua Edition because I didn't want to take any risk! But to each their own, I guess!

How many people are running 4090s with them right now? When was the last time you heard of a connector burning that wasn't noob error.

Still, if they had to make a 3.1 version it means it was not 100% safe from the get go... When was the last time you heard an 8-pin burning?!! I personally never did...

There's been a few, more than a few over the years. Some was user error, some overclocking, a few pigtails.. it happens. Actually I think there was one here posted not long ago.. could be mistaken.

8-pins have definitely melted over the years. But I think I mainly saw that with use of cable extensions of dubious "quality".

 

[x4it3n]

Wait and see for RTX 50s and this new 3.1 connector! But it better be a lot safer this time around.

 

[dirtyferret]

Well that's your POV

I was correcting your "POV' so it would not be mistakenly read by someone thinking you actually knew what you were talking about. Next time please take the time to educate yourself before posting on the forum.

Aris in reviews stated they were mostly done by user error or GPU issues, not on the PSU side once user error was removed.

3.0 is higher standard than 3.1.

If you can afford a 5090, can't you as well for a PSU ???????

I guess you're having reading issues then because I said "Well that's your POV, but I wouldn't risk burning a GPU that is going to cost me $2000..."
There's a reason why they made some changes on some of the pins, and people should be sure about what they bought (ATX 3.0 PSUs included), that's all. All those melting connectors should have not happened if they made those new connectors safer.

Also if you can buy a 5090 you can buy an ATX 3.1 PSU even though the new connectors will all be on the GPU side too.

3.0 is higher standard than 3.1.

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