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
Also re-reading your post, the circuit breaker to the outlet was tripped when this happened. Do you actually have power at the outlet you are using?
Make sure the outlet is grounded, and use a surge protector between the outlet and your PC just to be safe,
Could have been a power surge, I would put a power strip between PC and wall outlet.
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.
Dead PSU. It needs to be replaced. Possibly other components will need replacement if the PSU took them out when it blew.
you have 40% chance that the psu didn’t fry some of the power managment in the motherboard or gpu. also theres the nasty problem that may rear its head months later sort of like delayed damage where it may throw errors out of nowhere or just stuck on trying to boot. psu blowout is best avoided if you see the psu shut itself off or reset that is one of the few warnings.
