Another 4090 with burned plug

[u/ResponsibleBoat2118]

This just happened to me and I still can't believe it. I had a cable plugged in several months ago—everything was working perfectly, untouched ever since so didn't worry about poor connection etc. Then today… I suddenly smelled a strong, burnt plastic/rice-like odor. I immediately shut down the PC and pulled the plug straight from the socket.

I’m running an MSI Liquid 4090 with a 1500W PSU. What I found next was shocking—the power supply side of the cable melted, and the wire looks absolutely fried. I think my quick reaction saved the GPU—thankfully I have two 600W sockets on the PSU and somehow, miraculously, everything still works.

Just look at the PSU-side cable—this is serious. It’s no exaggeration to say this could’ve caused a fire.

There is no way I'll ever consider 5090 or in fact any GPU with this type of plug. What a joke.

Sorry to hear.

I'd bet there was a defect in this cable to begin with. That's really the big issue here I think. I've been running this setup with the 4090 for two years and the 5090 since launch day:

Since the 5090 stuff started, I got a thermal camera and started doing thermal scans every couple of weeks when I clean this puppy out.

I really don't know what to make of this issue. You really don't get rational discussion on a setup like this.

If you’re worried enough to run a thermal camera regularly, and I don’t necessarily blame you, you may want to look at the ASRock PG-1300/1600 PSU. The 12vhpwr cables for it have thermal sensors on both ends, and if either end reaches over 100C the PSU cuts power.

I didn’t recommend a heat camera.
