I recently bought a 500w psu to power my Q9550, striker 2 formula and 2 HD5770 graphics cards since plugging this psu in no video has come but everything powers , have tried different board and different CPU and still the same thing even when using on board graphics in the second board , tried again using a 250 w psu and still nothing , I'm guessing the aerocool psu killed both boards , both worked fine before upgrading
