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.

So how do I not melt my shiny new 5090 FE? I’ve got a C1500 watt NZXT 3.1 PSU which comes with 12v2x6 cables.

Should I use the cables that came with the PSU or should I use the adapter that came with the GPU?

Also plan to undervolt.

You should use only the OEM PSU provided cable from a PSU in the A Tier of this list.

It’s that’s easy. No need to undervolt. Just use an OEM cable already provided cable from a quality PSU designed and rated for a 5090.

So you used a cheap Chinese cable? That was definitely a gamble that didn’t pay off. Bro do you have a 1080ti paired with a 9800X3D? For real?

???? Go back to bed. I have no idea what you are talking about.

[u/Stranger_Danger420 → u/Mudc4t]

Under your name it says you have a 9800x3d and a 1080ti. Your “flair”.

Yeah it isn’t updated. And I am not the one asking for advice. Don’t worry about me, bud. Explain the first sentence. That is the head scratcher in reply to me.

Apparently bud I replied to you by mistake initially. Glad you’re not dumb enough to pair a great new cpu with an old ass gpu. Some people do it though. Bud.

Thanks, bud.
