CaseBuy EZ Power Supply Tester
 

CaseBuy\'s EZ Power Supply Tester is very easy to use and it will tell you if you are getting power on a rail. Just don\'t expect it to do any more than that. This little gadget can save you a lot of time by weeding out dead power supplies, but you\'ll want to have a multimeter handy to make sure that you\'re getting the right amount of power from your rails before you use the PSU you\'re testing.
