Evening all,

Got home last night and went to turn my pc on. Pressed the push button and bang. Whole house went dark. I reset the CB and pc won’t turn on. No lights on motherboard at all. For context, the PC was used in the morning with no obvious issues.

I’ve tried a known working cable to the power supply and no luck. I don’t have a spare PSU to try to test the rest of the PC. I also don’t have another PC to see if the PSU is fried or just motherboard. I also don’t have a multimeter.

If I go and purchase another PSU to try with my PC is there anything I should check before just plugging it in and potentially blowing another supply?

Thanks in advance
