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

    Well if main house circuit breaker trips and PSU is not responding in other power sockets with a new power cable after said event - it’s going to be a PSU replacement anyways. Something shorted badly… Not likely PSU fault, usually some outside factor. Luckily this short happened in the PSU at a place which is located before power is being delivered to your PC components. As quality PSUs (which seasonic is) usually have some protection in them, there’s a good chance all of your other pc components survived. HDDs and SSDs can go fairly easy though, so I hope you had backups of your important items.
