I believe my PS went out

[Jester73440]

I believe my power supply burnt out but before I run out and buy one i'd like to make sure that is the problem. computer shut off won't come back on and no internal lights are coming on. safe to say I need a new power supply ?

You can test it with a multimeter. If you have one.

There's also a way to jump start the PSU
