Corsair HX850W enough for this system or return for HX1000W?

[TheWhoDat]

Hello all,

I am an previous Antec and PC P&C user.

After all the positive reviews and recommendations, I decided to go with the Corsair HX850W for a MATX build.

Well, after a couple of backorders, and other issues, I went ahead and built a Full Tower ATX instead.

I kept the Corsair HW850W for this setup, will this be enough?

Core i7 920 (will not overclock much, if any)
EVGA x58 SLI MB
LG Blu-ray burner
Samsung DVD burner
Current have 2 X GTX 260 - will upgrade to GTX 285 or GTX 285 SLI(Need to use the 2 x GTX 260 in another machine.
Velociraptor 300GB
640GB storage drive
X-fi sound card
HAF 932 case with all fans installed

Am I at my limit for this PSU or do I still have room to upgrade with?

Or should I try and return the Corsair HX850W for the Corsair HX1000W?

Thank you,

Joe

you're more than fine. even with two gtx285's pulling maximum power.

The HX850 has more than enough power for that. You shouldn't have any problems at all.

What they said.

HX850 could probably handle 3 way 285s, though that might be pushing it's upper limits a bit. i have seen some sites do it though. you should be more than fine with 2 285s on one. if you are really worried about how much draw you are using on your PSU, the cheapest way to figure out how much you are actually using is to just get a kill-a-watt (TM) device and measure from there. whatever you are drawing from the wall, ~80-85% of that is what you are putting on your PSU. for example, my Q9650 + 2 barracudas + 2 F1s + a Vraptor + 6 fans and controller + 2 CCFLs, a 9800GTX 512mb 65nm, a BD drive and a DVD drive (burning DVDs) and 4 USB powered devices all in all draws ~420 Watts under OCCTv3 PSU tester.
