Power supply blown???

[TomDow]

Hello, I was playing the new Microsoft flight simulator for about 10 minutes and then suddenly my pc just turn off, now my pc is prone to restarting because of the power supply but this time it didn’t restart it just turned off but when I tried pressing the lower button nothing happened, now the keyboard and mouse still lit up along with the motherboard rgb but it wouldn’t turn on m. I pulled the cable out and put it in again but then when I pressed the power  button the cpu light on the motherboard flashed now i dont know if that was just faulty and was supposed to stay on but the board was just a week old. So please help me :(

Can you provide more information about your system, including what model of power supply you have.

 

Do you have another PSU you can use to test with?

watch what kind of flashing that CPU light is doing. Your motherboard manual might have a section of codes for it or the manufacturer may be able to tell you what it means. A new PSU might be in order but it may have killed something else as well, so you need to find out if that light means something like the cpu has no power or something like the cpu is fried.

Yes I have a Ryzen 5 2600x m, b450 aorus elite and the power supply is the cit builder 500w power supply (was getting a new one whilst this happened)

Oh, yeah. Those are absolute garbage. Would not surprise me at all if it died. Also not actually a 500W power supply, the label states 12V rail can only output a max of 22A (264W). 12V rail is used to power most things in the system, including CPU and graphics card.

(Update:  Looks like there's another one that's rated at 30A on 12V according to the label, but still the same problem)

 

What graphics card are you using?

A gtx 1060 3gb dual fan

If you know the system is prone to restarting because of the PSU that's an indication of either over current protection or a rail dropping out causing the system to crash. Regardless of what the actual problem is here I'd definitely recommend replacing that.

 

Do you have a spare PSU we could start troubleshooting with?

So I take it after the CPU light flashes the system doesn't turn on yes? You could try disconnecting all cables leading to the PSU then short the PS_ON pin to ground.

 

See if the PSU turns on and stays on for one. Then if you have the resources check each voltage rail with a multimeter.

Are there diagrams of these pins on the internet because I don’t want to blow myself up?

Ok so I found the diagram and I will do what you said when I can. So if the power supply turns on when I short it’s not the power supply but the cpu??

No. It could still be the PSU. That'd be where a multi-meter is useful for checking the 3.3V, 5V, & 12V rails individually. Weather the PSU is fine or not I'd replace it with something from Corsair or EVGA. The forum has a PSU tier list if you think you have the funds for a replacement unit.

So I did what you said and tried turning the psu on and nothing happened, so I’m guessing this means that the power supply has just died??

Assuming the wires on the PSU are color coded and you shorted the only Green wire to any Black and the PSU switch is turned on and the unit is plugged in to the wall and it didn't turn on at all then yes. Your PSU failed and you need a replacement unit.
