Handful of users claim new Nvidia GPUs are melting power cables again
-
Yup. Pretty dumb.
-
The person on reddit used a third party cable instead of the one supplied with the device.
https://www.reddit.com/r/nvidia/comments/1ilhfk0/rtx_5090fe_molten_12vhpwr/
It melted on both sides (PSU and GPU), which indicates it was probably the cable being the issue.
-
That's bad, but that aside - It might be time to consider alternate power delivery to these cards. The power they need should warrant having a standard c13 plug directly on em or something.
-
A mini fusion drive, perhaps?
-
Running 600W for 12 hours a day at $0.10 per kWh costs $0.72 a day or $21.60 a month. Heat pumps can move 3 times as much heat as the electricity they consume, so roughly another $7.20 for cooling.
All electronics double as space heaters, there’s only a minuscule amount of electricity that’s not converted to heat.
-
Are people improperly connecting them again?
-
Four of the standard 8 pin PCIe power connectors would work well.
The new connector really should have used some large blade contacts to handle 50 amps. -
All that cost and this is what you get…
-
My +20 year old GTX780 would pull 300W at full tilt, and it has only a ridiculous fraction of the compute power. high end GPUs have been fairly power hungry for literally decades.
-
GTX 780 released in 2013?
RTX 3090 was 350W?
RTX 4090 was 450W?
So if by decades you mean this generation... then sure.
-
Haha yeah I mistyped the years, it was supposed to be +10 and not +20...nevertheless these cards have been pulling at least 3-400W for the past 15 years.

Power the house with it when not using the PC, but expect brown outs when gaming.

What I've learned from this whole fiasco after owning a problem-free 4090 for over 2 years:
- Don't use 3rd party connectors, and don't use the squid adapter in the box. Use the 12VHPR cable that came with your PSU or GPU. If your PSU doesn't have a 12VHPR connection, get one that does.
- Don't bend the cable near the connection. Make sure your case is actually big enough to avoid bending.
- Make sure it's actually plugged in all the way. If you didn't hear a click, it's not plugged in all the way.
- Don't keep disconnecting the cable to check for burns. The connection is weak and designed to fail after only a handful of disconnect/reconnects. If you followed the 3 steps above perfectly, you have nothing to worry about.
That said, I'm skipping this GPU generation (and most likely the next one as well). Hopefully in 2-4 years AMD or Intel will be on more level grounds with nVidia so that I can finally stop giving them money just to have good ray tracing performance.

I got lucky and picked up a 7900 XTX for a reasonable price last gen and it's been a really great card. I've got a couple systems coming up on needing a refresh (1080 Ti and a 2080 Ti) and I'm planning on upgrading both of them to a 9070 XT. I'm staying away from Nvidia until they start pricing their GPUs at prices actual consumers can afford instead of corporations looking to build AI farms.

Strolls nervously through room with RX 580...

c13 plug
Who would've thought.... 3DFX was apparently ahead of its time...
-
I really appreciate the specificity of the headline, rather than the clickbait it could have been.
-
Better would have been:
Handful of users complain about 3rd Party Cables Melting Their 5090FE.
-
Yeah my 3090 K|ngP|n pulls over 500w easily, but that's over 3 8 pin PCIe cables, all dedicated. Power delivery was something I took seriously when getting that card installed, as well as cooling. Made sure my 1300w PSU had plenty of dedicated PCIe ports.

Is this the fabled Bitchin' Fast 3d?
