PC Went Black Without Warning, Would Appreciate Any Help Diagnosing the Issue.

So, I come back from a quick trip away from home and enter my PC, I'm sitting there playing Yakuza 0 and the thing just blacks out by itself. I thought maybe it was a blown fuse, yet all of my other electronics were working fine. I have it plugged into a higher end outlet strip and I don't do any overclocking that would cause any problems.
The PSU test did cause the fan to work, I cleaned out the system, reapplied thermal paste, re-seated my GPU and RAM, nothing.
To pinpoint what happens, if I turn on the PSU, *I am able to power on via case for less than a second, my GPU and motherboard LEDs are the only things that power up for that same amount of time* (the motherboard LED actually radiates for as long as the PSU is on..) I am then unable to power back on unless I reset the PSU and the same thing occurs.

Specs:
ASRock Taichi x370
Ryzen 1600X
Corsair Vengeance 3000mhz 16gbs
EVGA Supernova G2 650w
XFX Radeon RX 470 4GB

    Even if the PSU self test shows that it is working? I felt like I had reliable equipment, and if I were to buy another PSU it would have to be an upgrade to my current one. Thanks.
  3. witch test did you use for the psu .

    EVGA PSUs come with a Self Tester that translates power to the fan similar to using the paperclip method, the fan does spin when using it, as if it were working.
  5. even if fan spin psu could have a issue use occt to stress test it for about 10 min and see .

    Bought new PSU, same situation as before. Motherboard is still flashing green, but it doesn't give me an error code. Could that be my problem ?

    I Made a mistake, the new PSU is running the system. Now I am recieving error code 0d on Dr Debug, I have already done the cmos reset with jumpers and reset all memory related components and I am getting the same error.
    What was wierd, I got it to POST when i messed with the CPU cable. I thought that might've been the problem with my orignal PSU, so I installed it again and it didn't work. I then reinstalled the new one and now have this problem. It seems that I cannot win.....
