How about this powersupply?

Now, I've decided to upgrade, and was wondering if this new stuff would run on my new powersupply;

Phenom 955 (4.0GHz)


2 7200RPM Drives

2 SSD's (60/90GB)

HD 7850 2GB

8 Fans (3 are from previous build, and I am buying 5 more, which the 5 will be on a Fan Controller)

NZXT Mesh Fan Controller

H60 CPU cooler

All on a OCZ 700w powersupply

I tried a few PSU calculators, but they gave me really off results (380, 427, 965...) and was wondering if someone here could possibly give me insight...

I'm curious about something also,

It says 5 '30w' channels, so does it take up 150w, or is that just the max it can take up?

It will run.

The fan controller means it can output 30W on 5 different channels!

Okay thanks, yeah the fan controller had me a little confused... Would you happen to have an estimate on how much this would take up, out of the 700w on normal gaming use?

A system with a single HD7850 requires a 500W PSU with at least 28A on the 12V rails and one 75W 6-pin PCIe power connector.

In all actuality a good quality 400-450W PSU is enough for a single-GPU 7850 system. The system isn't likely to use more than 260W or so at full load. A system with a highly OCed i7 965 and a HD7850 used 256W in this review:
