So this morning I swapped out a 550W Antec true power supply I do believe, I'm not sure of it's rating or whether it has one. I have my 4690k at 4.0-.4.2 Ghz, 2 monitors on and was using roughly 130-140w on Average Idle With the Cooler Master V650 I replaced it with, everything plugged in the same, nothing added or taken away (yet), and the power usage is around 150-160 with just 1 monitor, and 180w with 2.. is this psu faulty or... Am I doing something wrong ?
