Question No Power - Faulty PSU or Motherboard?

[bunbun33]

I have been facing issues powering up my system for the past 4 days, LED lights on motherboard in on though. The puzzling issue is at the start of each day, I am unable to power up the PC. Each time I had to try out different method, opening up the case, disconnecting Power Sw from the panel and etc. And after messing with it for awhile I was finally able to power up the PC. Subsequent power up throughout the day will work and I can even get to game the entire day without any single issue.

For instance, just today, I had the same issue and had to try out different methods. I removed the power switch pin and tried to short the pc to power up but to no avail. However, after I placed back the power SW pin back on motherboard, the power button on case works miraculously and I was able to switch it on again. This makes me wonder what's exactly faulty here and I need your advise.

Thank you in advance.

Welcome to the forums, newcomer!

PSU: THERMALTAKE SMART RGB 600W
That isn't something that shouldn't be anywhere near a system. Perhaps try and source a donor PSU(borrowed from a friend or neighbor) with at least 550W of power for the entire system's disposal to rule out your unit being the issue.

If you have to reseat components, it's quite likely a grounding issue...

My apologies, i don't really get this sentence. Can you elaborate further.

Judging from things now, am i right to say that it doesn't seem like a mobo is failing?

Thermaltake's SMART range of PSU's aren't good quality units. it's hard to say if it's a motherboard issue.

What PSU did you replace it with?

CM MWE Gold 650 v2. Right now it seems my power from wall socket must be switched for awhile before my pc can be turned on.

Relocate to another wall outlet and see if the issue persists.

I had the same issue a couple of years ago and it was an old contact in the wall socket overheating with too much load and would trip my pc. I t took me ages to diagnose it as i could not beleive this would be the issue!
