NV 12VHPWR issues revisited

Jensen Edition card: Black, shiny and FAT!

 

[igor_kavinski]

Maybe wont burn or melt, but being a Gigabyte card, the PCB may crack. 😛

Or the power circuitry may go up in flames.

 

[amenx]

The pic of the Gigabyte card from Tom's article shows the same retaining tab gap that is supposedly causing the PCB cracking.

But at least the 12VHPWR is now OK. 😀

It burns both ways! 😀

Another one melted after 7 months of use.

The connector is like herpes, it just won't go away.

User Reports 12VHPWR Connector Melting From the PSU Side (Updated)

This time it's not the end on the GPU that has the issue.

www.tomshardware.com

Tom's Hardware has reached out to Nvidia, as well. An Nvidia spokesperson said we may not hear back for a few days due to a company closure.

LOL, Jensen went shopping for mink fur leather jackets or something?

I suspect they'll keep quiet just like bumpgate and 970 4GB. Then after 2 years 4090 owners will get a random email saying a $23 check is waiting for them from a settlement. 😵

With $25 in fees to actually get that money.

It took a while ... but here it is:

be quiet! Dark Power PSU Owner Reports Melting of 12VHPWR Connector

A member of the amusingly named and low populated r/4090Burning subreddit has reported a strange incident where the PSU side of his 12VHPWR connector had melted. Shiftyeyes67k shared his equipment's plight two days ago and included two photos with his story: "Started noticing a smell coming from...

Obviously user error ... /s

Everyone in the green camp should admit defeat at this point and go back to making cards with multiple PCIe connectors.

All powerful benevolent god Jensen will never bless that.

... also, please report to your local inquisitional branch office for dogmatic adjustment. You are straying from the faith and your soul is in jeopardy. I understand you may have heard rumors about the inquisitional offices, but I assure your that Nvidia's profits for this quarter are far more important then any tempory physical discomfort you may experience. May Jensen be with you.

Just swap to EPS12V and then you get 300W from a single 8 pin.

Been used in servers for many years.

 

[NTMBK]

Ditch the PCIe card format entirely. ATX was never designed for 300W daughter boards.

We need a new chassis design that takes SXM boards.

Power delivery through mezzanine connectors, problem solved.

EDIT: Or use OAM, the non-proprietary version that AMD and Intel are supporting.

 

[BFG10K]

ATX was never designed for 300W daughter boards.

Very true. Likewise it wasn't designed for 1kg CPU coolers, M.2 water coolers, and 1kw PSUs.

The problem started with "turbo core boost" et al, and has culminated with redlining voltages in order to chase the last 5% performance to make pretty benchmark bars. This is why we have 5-slot bricks from NV, and AMD telling us a constant 95c CPU at load is "intended design". 😵

The answer is to boycott these furnace monstrosities. If nobody bought >250W GPUs and >65W CPUs, companies wouldn't release them.

A tiny Intel stock cooler can handle a CPU power-capped to 65W just fine. That's exactly what I've done. No more ridiculous tower of metal(tm) hanging from my motherboard.

 

[BFG10K]

Look at the wiggle even with the clip engaged. All it takes is a slight cable pull to dislodge it.

Someone actually signed this off as "OK" for connector rated for 600W. Whoever approved certification for this is an absolute moron. 😵

 

[amenx]

Also in the vid he says cablemod reports that 70% of these issues came from one brand (AIB) card maker.
Btw, I have no wiggle at all on my cable connector. Manufacturing variance obviously can be an issue here.

He won't name the brand. I wonder who it is? Gigabyte?

 

[DAPUNISHER]

Gigabyte?

That's the strongest candidate from reading around.

I've been a little worried. I just got the Asus strix 4090 OC.

Don't worry, at most you'll be out $2k.

is the damage typically limited to just the GPU?

or does it also take the PSU and other components with it?

It seems like a burning connector would act like a short and do some crispy shorting arcing rf damage. But perhaps not with nice new modern PSUs.

 

[Aapje]

is the damage typically limited to just the GPU?

Yes, I haven't heard of a case where anything else was destroyed, other than the cable, of course.

Classic survivorship bias, you don't hear about the ones that burn down the PC because they can't post on Anandtech any more! /s

Link posted earlier. 1 PSU casualty.
