PSU Dead? Need troubleshooting advice

post #1 of 10
Thread Starter 
Recently I was just using my computer, it's about 3 years old at this point, and it just died all of a sudden. I can plug it in into a live outlet, but nothing happens. That makes me think it's the power supply, but I'm not sure.

I have a Corsair AX850 modular power supply. Is trying to submit an RMA request the best option or should I try another power supply to verify that it is in fact the problem?

Thanks.

unplug all cables from mainboard and plug them back and try to start off

Yeah, I've tried that. Doesn't seem to change anything.

You can test the power supply without it plugged into any components except a case fan. Corsair have a guide on their blog.

Thanks for this link!

I just tried this, and the fan won't power on. All signs lead to PSU.

No worries!, If you've tried other electrical outlets i'd see what Corsair say about the RMA. I hear they are quite good with replacing faulty units so you shouldn't have any problems there.

It's a 7 year warranty and I've only had it for about 2 years 11 months. But yeah it seems like it's the PSU I can only hope the other components were not affected because I heard a shock noise and my pc just powered down. I'm going to submit an RMA to corsair soon.

Does anyone know if I RMA this, will they require me to send all the modular cables or just the box? Thanks.

if you rma you should send to them everything that comes in box. thus they will probably send you new unit
