Hi. Hope you can help me calculating the wattage my system is consuming when in IDLE, I wanna know 'cause I tend to leave it sometimes downloading heavy archives (that takes HOURS to finish) and since It's the only PC I have I need to know if It's worth it to leave it downloading ('cause the energy paybill). I already did the "recommended" PSU test using the eXtreme Power Calculator, according to the test my system at 100% load needs a 700W PSU. I have the exact system in my specs. The CPU in IDLE drops down to 960MHz using 1.12v and my GTX280 IDLEs at 300/100 (core/mems) using 1.0375v. (I used CPU-Z and GPU-Z to read the values). THX for the replies.
