I just bought a new corsair TX650W power supply. Before installing, i tested it with my power supply tester and got the 5V on the upper bound of 5.3V. I then tested it with a multimeter and got 5.28V on all 5V lines. The tolerance for that line is +/-5% ( which means a maximum of 5.25V, and I'm getting +5.6% ). Am I making a big deal out of nothing here? Or should I RMA this power supply?
Thanks for all the answers! That puts my mind at ease. Once I get the system built, I'll test it again, out of curiosity, and post the reading that I get.
To test it under full load, I would plug everything in, turn the computer on, then do the multimeter test on the 4 pin peripheral connector, with the black probe on one of the black pins and the red probe on the red pin?
