850w or do I need more
Aug 8, 2012, 6:29 PM
I'm currently in the process of doing a build and I'm stuck on how powerful of a PSU I need. Can I get away with use a 850w psu or do I need a more powerful psu.
The budget for the the PSU is no more then $250
Here's the build:
I7 3770k (I plan on overclocking to 4.2 ghz)
ASUS Maximus V Formula Mobo (I'm in loving with this mobo
G.SKILL Ripjaws X Series 8GB (2x4gb) 1600 DDR3 ram
2x GTX 660s (I plan to do a mild overclock on these as well)
2x 1TB HDs
SAMSUNG 830 Series 128gb SSD
Corsair H100 Liquid CPU cooler
BitFenix Recon Fan Controller
Asus CD/DVD + RW player
So any ideas?

You don't need 850W for that system. A good 700-750W unit will be just fine.

^+1. 750W should be enough. Seasonic, Antec, Corsair, XFX, Enermax/LEPA, or (new) FSP are the ones I'd consider. I've seen some good test results for the PCP&C units, but despite their name they are very loud under load.

Agree that 750W is more than enough for an OCd build with two GTX 660s.
The original Silencers were loud, the MK II units probably aren't seeing as they (all except the 950W version) use large 13.5cm fans with maximum speeds of 1500RPM and noise rating of 29dBA.
Although with a $250 dollar budget I would definitely buy something else.
