I agree with sandstorm and roughly calculated you system specs as best I could and @ 100% load and your would be only using 342 watts. Now I understand the fan on the RM series does no kick on till about 40% load, or in your RM650 case 260W. Given that your system would need to run @ approximately 76% load all the time for the fan to kick on.


Heres the calculator for you to check your real wattage usage. psu calculator lite
