TeToxDK Posted July 8, 2009 Share Posted July 8, 2009 Hi! I want to ask how i can measure the voltage on the +3.3v and +5.0v lines, with the computer powered up?? I checked my voltages with software and it reports the +3.3v, as low as 3.04 under load, and the +5.0v at 4.75... I know the software can give you false readings, so i want to check it with a multimeter, to check if the PSU is good or bad.. Thanks Link to comment Share on other sites More sharing options...

Corsair Employee RAM GUY Posted July 8, 2009 Corsair Employee Share Posted July 8, 2009 You can check the reading in the BIOS. If you have a multimeter, you need insert the negative into the ground pin and positive into 3.3v or 5v pin. Link to comment Share on other sites More sharing options...
