[SOLVED] Motherboard or PSU issue

[iciclezebra]

Recently, I had to RMA my power supply after it broke and my computer had worked until Yesterday. The computer was sitting idle when all of a sudden it just turned off and never came back on.

Since the power supply is so new, I doubt is the problem and I think it is the motherboard.

Specs:
CPU: Intel Core i5-7600k
MB: MSI z270-A-PRO
RAM: 16GB Corsair Vegenance 2400mhz
GPU: NVidia Geforce GTX 1060 6GB
PSU: EVGA SuperNova G3 650W 80+ Gold

Could be the board or PSU. I had a similar situation and the problem was my ASUS HERO board.

A multimeter to measure the voltage from the power supply main plug should give you some indication if it is alive or not. But you said you got a replacement power supply and still a dead computer?

The PC worked with the replacement I got until two days ago.

So the computer worked for a while with the original PSU, and then failed, and then worked again with the RMA'd PSU, then failed again? If you put the RMA'd PSU in another PC or check it with multimeters, is it still working even though your computer is no longer functioning?

MOD Dark Lord of Tech, if it was the MOBO creating these issues, could you please elaborate?
