PSU's For 580's

[toxic]

Guys

Whats the minimum PSU required for

1. A single 580 in a 2500 overcloked system to 4.5Ghz

2. SLI 580's in a 2500 overclocked system to 4.5Ghz.

Cheers if you can assist...Im needing to buy a new PSU with my new GPU. I just cant decide if I want to go single on SLI yet.

A quality 650 - 750w for single, you could get away with a 750w for SLI, But 850w would be fine.

I pull 500w with my system in sig with Furmark and prime running.

How would that be covering the fact that I may go 580 sli...if I buying a single 580just now?

Seems like a good price/power ratio.

How about this one:

OCZ Z-Series 850W '80 Plus Gold' Modular Power Supply

Gold rated and the full 850W available on the 12V rail (which is the important one).

The Lepa is only 80 Plus Bronze rated and only has 750W available on the 12V rails.
