Short Answer - Yes.

I have a 850 PSU power my rig below.

For your current build you only need 450W....even going nuts with HDDs you're only going to need another 100W. Possibly a bit more if you're going nuts with case fans.

Yep. Good 500-600 watt power supply would be sufficient.

the http://support.asus.com/powersupply.aspx calculator give me a calculated of 950watts..

that scared me earlier.

So 850w is good?


thanks!

That is the WORST calulator I've ever seen.

You need no more then 600w.

This. It overestimates the draw on my system by a almost a factor of 2x.

OP, the only PSU calculator I trust is written by PSU gurus FiX and Phaedrus, and can be dowloaded from:
