Poor Performance with NVIDIA 4090

I just ordered a ATX 3.0 PSU. Perhaps I would have been fine, just don’t want to take any chances. 

I don’t think there’s any tension on my adapter as it’s basically hanging straight down from the GPU. But with a new PSU I’ll get a cable with 12-pin in both ends.

But if it's a tension issue what would be the difference from the not ATX 3.0 connections compared to the 12 to 12 cable?

If you make sure there is no tension a not ATX 3.0 would and should  be fine

I am lost in this.

I’d rather be safe than sorry. Really don’t feel like having the adapter at all if it can be avoided. With a 3.0 I’ll get a dedicated cable.

There are some other advantages with 3.0 besides that, but if it weren’t for this adapter issue, I wouldn’t have rushed to get one.

NVIDIA just notified all AIC this morning…  All damaged cards need to be sent directly to HQ for failure analysis, this is first time… Even few years ago when 2080 Ti got issue with Micron, they didn’t do this.

I'm guessing its a combination of factors... 

• Poor adaptor design that tries to splice multiple heavy gauge wires together in a tiny connector - solved by having an ATX PSU cable
• Poor adaptor design that doesn't evenly distribute current across the pins of the ATX connector - solved by having an ATX PSU cable
• Card is drawing more current through some pins than others - no solution outside of a card redesign
• Strain on the cable either stresses or breaks above splices - solved by having an ATX PSU cable
• Strain on the cable creates poor contact between pins and socket - solved by reducing strain
• Q/A issues where some adaptors are faulty - solved with any new cable/adaptor of any kind

So an ATX power supply and cable are most likely to solve the bulk of potential issues.

Or another 12VHPWR adapter cable that costs € 25 / $ 25…..

Be Quiet has released one.

It really depends on how the different adapter has been designed. It could suffer from the same issue as the Nvidia design.  In my view, the best way to ensure you don't have issues with an adaptor, is to not use an adaptor.

Install a smoke detector in the PC with texting ability, problem solved, haha.
If you paid $1600, what's an $80 smoke detector.

It’s not clear to me how it’s designed but the issue is how Nvidia, or any other adaptor gets multiple 12v wires (and as many or more grounds) into 6 pins on the card.  It sounds like the BQuiet goes from two 12 pin connectors (24 conductors) on the PSU to a 12 pin ATX 3 connector for the card. There must be some splicing going on. Where and how is the splicing been done is the key. If it’s like Nvidias adaptor that does the splicing in the tiny 12 pin connector, it may have the same issue.

I still maintain the best solution is one without any splicing... 12 pins out of the PSU straight into the card.

There has already been too much press on this, so Nvidia has no choice but to change the card eventually, whether that be a new connector on the card itself or just a new adapter, something, probably both eventually. AMD 7900xt release info on this next Thur (Nov 3rd)...

For the price, they should include a 1000W ATX3 PSU in the box 🙂

They make more money apparently from their super-computer division GPU's which cost around $80,000 each.
So I guess they don't really care as much.

With all that "deep learning" AI logic that exists in their DLSS (wink wink), you'd think they'd at least have enough AI to spot a bad connector.
I guess Robby the Robot "bad-connector" - "detector" was off that day.

That’s an interesting design, as it’s 12 conductors on each end so no splicing. Not sure how that affects the legacy connectors though since you’re now using only two power and ground from each rather than three power and four ground. And of course, this adaptor only supports three PCIe legacy connectors so it’s not full (600W) power spec. They mention they will have one with four next week, and it will be interesting to see their design… will they then have to splice conductors as well?
