What psu to buy

[iamsneaky13]

I have a system picked out And am stuck on a psu. I have the phenom2 955, 2 radeon4870's, 2 hard drives, 1 ssd, the thermaltake bigwater liquid cooling system 6 gigs of ram. I am looking at the corsair hx850 Or the Hx1000. I don't know much about psu's but I want a high. Quality one. Any help is appreciated

You would not need another psu ever, if you got the 1000.

It's $50 more though. Will 850w power all that stuff? I might expand for 6 or more drive

You've got a lot of stuff running.

I would get the best you can afford.

The 1000W Corsair is actually 2 x 500W Corsair psus bolted together but is a remarkable piece of kit. The 850W is also amazing with over 80% efficient at all loads, 5 year warranty and slightly smaller than the 1000W.

I would get the 850W one as with 70A on the 12 V rail it will be loads.

I have the 850W corsair PSU and it runs fine. My rig is only probably on about 60% load, yours would be on about 75-80% . It is always over 80% efficient, always cool and is very quiet and also comes with a 5 year warranty,so will last for a very long time. 850 would be enough for your system and the TX850 is actually able to run at 900W, it is officially rated 800-900W so they just smack the middle value on it, but I wouldn't want to run it at 900 for long, not that it wouldn't be able to handle it, just that it may end up getting fairly hot

850 watts on a Corsair unit is plenty. 1000 watts, in your case, would simply be for a bigger e-peen (and a lighter wallet).

THe 850W is plenty for this rig, and heck, even if he upgraded to dual gtx295 and i7 an 850 would handle it.

ok i'll go for the 850.
