Motherboard doesn't get power with GPU. Turns on without GPU

[hasanuzzaman]

My build:

i7-9700k

gigabyte aorus z390 master

zotac rtx 2060

cooler master 650W 80 plus gold

My pc has been running absolutely fine for 3.5 years. But after updating my gpu driver recently the pc got completely frozen. Even power or reset button wasn't working. I had to unplug and re-plug to restart the computer. It ran fine for a couple of hours. When I left to do something else for around half an hour,after coming back I though my pc was in sleep mode as usual. But when I pressed power button I just heard a click sound from psu and pc didn't even post. No fans were spinning. The ram rgb lit up after a while and nothing else happened. Upon further pressing power button nothing else happened. When I turned off and on psu switch and pressed power button again, I heard the same click and the same thing happened. When I took out the GPU the pc started normally. None of my friends own a desktop so I can't check with another gpu or system.

I took my pc to a local repair shop and they checked with a low power gpu (didn't need pcie power cable), the pc again turned on fine. They didn't have a power supply suitable for checking my GPU so I brought it back home.

Now I want to take my gpu or psu to the shop I bought it from. It's not possible to take the whole pc due to some issues. Sadly gpu warranty period is over but PSU still has warranty left. So if the gpu is actually dead I'll have to get another one. But I'm unsure which one is causing the problem and which one to take.

Please help me figure out what to do at this point.

I saved up for years to build my pc. If I end up replacing the gpu, I'll have to settle for a gtx1650 or rx6400 since gpu prices has increased in my area and my budget decreased. So I kinda hope the psu is causing the problem. It really breaks my heart when I think about the whole ordeal. I wish better pc parts were available at similar price or same parts at a cheaper price after a few years but that is not the case.

I'm willing to be the PSU is the culprit here, but it could be your graphics card as well. You gotta get a proper PSU to test to be sure though.
