24pin connected and mobo shuts off

Recommended Posts

Posted · Original PosterOP

Hello. I've recently sold my GTX 1080 Ti, as I am looking to upgrade. I currently have no graphics card at the moment. After I sold the card, I turned on my pc (without card) just to test it out, which it did for a few seconds and turned off for no reason. After that incident I could not turn it back on, and I have tried everything to test if it was the power supply or cables. And yes, the psu cables are the ones that came with my psu. But however, I tried using the 24 pin with the black and green wire method, with the 8 pin for the CPU turning the fans on, and then connecting 24 pin with the pin inside, immediately shuts the whole thing off.

Is it possibly my motherboard?

 

P.S, pls give a valid answer and not a yes or no, as I'm deeply numbed out, having no where to find the correct answer.

 

Thanks.

first off. DO NOT DO THAT!

shoving live voltage to a motherboard will damage components (if not already done).

you'd short the terminals (on the motherboard) to the front panel power switch to power the system while the 24-pin connector is connected to the motherboard.

the blk/grn short is for PSU testing alone not power the system. when the short remains while connecting to mobo is like holding the power button on the front panel.

try to use the motherboard pins for the front panel to power the system with the 24-pin connected.

Did you turn off the PSU when removing the GPU?

Welp. I've tried everything before doing the jump test. So I'm guessing it's already been deas

I don't exactuly understand your instructions. How would the pjn connect to the front panel?

what motherboard?

you'd plug your front panel connections from the case to this area of the motherboard to power the pc, HDD activity light and power on light w/reset.

Idk what you mean, but it's always been connected to the motherboard
