GPU Getting Hot When Computer is Off

I commend you.  But it could lead to a fire hazard, altering cabling of a psu. Also, that seems to be a low grade PSU in general.

 

as for your ‘issue’. Why not use the off/on switch on the backside of your PSU? Just flick it off and that way no power goes to the PC anymore.

Hello,

I recently noticed that while my PC is "shutdown", my GPU gets quite warm (too hot to touch and over 50 °C immediately after boot). Temps are totally fine when the computer is on (usually around 30° at idle), and I noticed the problem after about half an hour of shutting it down, so it's not because it was hot before turning it off either. There is one other notable thing though: Because of the way my PSU is attached to my motherboard, the power supply doesn't turn off when the computer is off (see below). My thought is that the GPU is still drawing power from the power supply through the 8-pin connector despite its off state (though I have no idea why), and the lack of any fan movement causes it to get warm.

 

The power supply thing: My motherboard had a lack of an ATX 24-pin connector, and instead uses a dual 4-pin setup. I did some research and hackily re-wired a few pins from my PSU's 24-pin to the "proprietary" CMDPWR header on my motherboard (thanks HP) with added resistors for good measure.

 

Everything works 100% fine when turned on, it's just when turned off that it appears to have problems...

 

System specs:

MB: HP 8653

CPU: Intel i5-9400

RAM: 2x SK-Hynix DDR4 2666Mhz 8GB (not sure on exact model)

GPU: RTX 2060 (PH-RTX2060-6G by ASUS)

PSU: ARESGAME 500W something (Amazon link for more info: ARESGAME AGV Series 500W Power Supply… : Amazon.ca: Electronics)

 

Thanks in advance for any ideas/suggestions you may give!

Don't worry, the pins I re-wired are simply for communication between the PSU and MB and carry very little current (especially with the "added resistors"). As for your solution, it does work, but my computer is in a fairly hard-to-reach spot under my desk, and it would be difficult to reach the switch every time I turn it off... Is there any way to fix this without needing to use the switch?

Power strip with a switch maybe?

No idea. You are using a proprietary board. You DIY’d the cabling.

Oops, I forgot to use the quote in my last post! I’ll use one of the switches mentioned. Thanks for helping!

yeah, get a proper motherboard,  and psu. (honestly its not a good psu at all)

 

otherwise

 its great you got it working like you did,  but i don't think its entirely safe, or practical.

 

 

The direction tells you... the direction.
