High Power Absolute 1000W enough for this system

post #1 of 5
Thread Starter 
Hi guys

I am just about to buy a new PSU; High Power Absolute 1000W

i7 920 @ 4GHz (1.35vcore)
Asus P6T SE
2 x Sapphire 5870 CROSSFIRE
Corsair 1600MHz 3 x 2 GB top 6 GB

I am niggling because I do not want to see any power problem.
And, best important question, what about 12V channels with High Power Absolute 1000W? Does it get along with two 5870 and overclocked i7 920?

DC Output: +3.3V, +5V+, +12V1, +12V2, +12V3, +12V4, -12V, +5VSB
Max Output Current: 30A, 28A, 20A, 20A, 30A, 30A, 0.8A, 3.0A

This outputs are ok with two 5870 and overclocked i7 920?

Sorry for poor english Thanks very much in advance.

If it's a decent 1000W, that'll be fine. You could run that system on a quality 750W.

You could get a quality 750W-850W PSU instead. See Recommended Power Supplies thread to determine what PSUs are worth buying.

Don't want to see any power problems? Buy a quality PSU, rather than just looking at the watts.

You don't need a 1000W PSU, your current unit is more than capable of handling two 5870s.
