Hey guys! Hope everyone is doing well today. I have a pretty big issue with a PC I built from somewhat old parts. The power supply started off running consistently, and I actually had it running (no video card though) on the BIOS screen for some time. It properly read and showed my CPU and RAM information. Then, when I went to restart it, it just stopped turning on. When I turn the PSU switch off and back on and start the PC again, it flickers for a split second then it turns off. Sometimes, if I connect a GPU to the motherboard, it will run for a few seconds, shut off, turn on and shut off within a split second again. Here are my specs, followed by more details:
GPU: Gigabyte GeForce 1080 Superclocked (used for maybe a year)
CPU: Intel i7 4790K Unlocked (No OC) (used for maybe 3 years)
Motherboard: Asus Motherboard Q87M-E/CSM (I forget....used for a few years at least)
PSU: Gamdias KRATOS M1-750B / 750W 80 PLUS Bronze certified ATX12V v2.2 Power Supply w/ Active PFC (brand spankin' new)
So I cannot test a different CPU or anything because my personal PC mobo has a different socket. I've gotten to a point now where I'm trying to jumpstart the PSU, and here is what happens. I put a wire or clip to jump the 4th and 5th pins from the top left row (with the clip facing up) like I should to start the PSU, and even when it is not connected to anything at all and I jumpstart it, the fan starts and stops instantly every single time. I'm afraid to try this PSU in my personal PC or try my personal PSU in this PC because I really, really don't want this possibly defective PSU messing anything up on my PC and I also don't want my own PSU to get fried by a bad board. I'm basically not entirely sure if the board or the PSU is the problem. I also don't want to go ahead and buy new components and then also have to buy a new PSU in addition to CPU, Mobo and RAM. Anyone have any ideas of what might be the problem component? I can also tell you I have tried starting the PC with only the 24-pin connector attached to the board, and without the CPU at all, both with and without the 8 pin (4+4) connector. As far as I know the PSU and fans should still be running constantly, but of course it won't post without a CPU. Either way the PSU starts and stops instantly. Sometimes, if I have a GPU plugged in as well, it will go for a few seconds longer and then stop, then it will not start again until I reset the PSU. Thing is, I don't believe the GPU is the problem, because the PC still doesn't start without the GPU plugged in.
Also, when I was first trying to start this PC with the GPU in, the white LED would just blink on the GPU and it wouldn't post. I cannot get it to do this anymore, it keeps shutting off.
Sorry if I was a little confusing. I've been running around like a chicken with its head cut off trying to figure out what exactly is the culprit component. I'd be happy to provide any more info.
