How to test if my PSU is shot?

[The_JMiner]

So I had my 500W PSU power one card on my mining rig (5830) and running my PC.  As I am browsing the internetz it all of a sudden died, I figured to let it cool maybe it overheated but it was not really even that warm. Ideas? Is it burnt? Ha get it!

I had the exact same issue earlier last week (https://bitcointalk.org/index.php?topic=38543.0) and, long story short, there's no easy way to test your PSU without going out and buying a testing tool.  It's probably easiest to just go out and buy a cheap 500W unit to replace your old one.  It was mentioned that the Corsair CX series is pretty good for the money

Did a google search and even got a multimeter and yea it is dead -_-
Good news is I get to buy a new one!

Just don't get a CX serie PSU ,,, for example the 600w cx is rated 480w, so it's not even a good 500w

What are you talking about? Maybe the older design was like that but the current V2 model is certainly rated correctly and tested by JonnyGuru to perform well under load even when above it's 30C rating.

Edit: ok, I see what you mean now. The 12V lines are rated for 480W only. But this is actually better than most other low-power units out there. Typically only high end PSUs provide the full rated load on 12V lines alone.

A lot of average quality 350-500 W units won't even handle 50% load 24/7 for long.
