Issues starting computer with Seasonic g-650W

So this has been an issue that has been in the making for quite some time. About 6 months ago my computer would not turn on and I thought that maybe my desktop had died. It did not want to turn on with the power button, but luckily I managed to turn it back on by flicking the the power switch on the power supply a few times. After that the issue seemed to come back once every few shutdowns, and seemingly only when I forced a shutdown like when Windows was reporting a program was blocking shutdown and I clicked "shut down anyway".

Fast forward to today and now every time I shut down my desktop it requires me to flick the power switch repeatedly, 10-30 times seems to do the trick, until the lights come on and startup begins. Other than the issue starting up, there does not seem to be any issue, even when I leave the computer on with my GPU's mining ethereum.

I did try the paperclip startup method at one point, but it did not seem to work. It could also have been my unfamiliarity about which holes on the MB power connector to bridge.

I doubt that there will be an easy fix, but if anyone has any ideas what might be wrong, that would be great! Otherwise I plan to RMA the power supply once I order a suitable replacement.

Current Specs:

Processor I-5 4690k cooled by a CM 212-EVO
Case: CM N400
GPU: 2 EVGA GTX 1070's (FTW DT + SC) non-SLI
PSU: Seasonic G 650W
RAM: 2x8 GB Corsair low profile Vengeance 1600mhz
MB: MSI Z97 SLI-Krait edition
HD: 2 x 500 GB Samsung EVO 2.5 inch drives (No raid)
OS: Windows 7 Pro

Thanks and Happy New Year!

  1. It sure sounds like your PSU is dead/dying. Out of curiosity, what happens when you hit the "reset" button on the front panel?

    If the computer's been shutdown, nothing. I have not tried it when it's turned on, but a restart from Windows will still have the computer boot up.
