Power Requirement for GTX280 SLi?

[mooch37]

Hey guys, my brother is going to buy a brand new rig soon and he wants to run dual GX 280's or whatever the best Nvidia card is on the market. Will a BFG 800 watt powersuply be sufficient enough to run those two in SLI?

should be,

[mooch37]

how sure are you?

[DanTheBanjoman]

He can't be any more sure than "should be" as you didn't specify any other specs. ie what model PSU and what other hardware is running in the system. Ar you running it together with a 1 disk RAID array or a single harddrive? Are you running it on a Skulltrail or a C2D?

The cards are quite powerhungry, that's for sure.

[mooch37]

He hasn't bought it yet nor does he know what specs, he was just wondering if an 800 would be sufficient enough to run both those cards in SLI. I know it would be better to have specs and all, but he hasn't gotten that far into it yet.

with powerful gfx cards its more about amperage than wattage, for GTX280SLi, you would want to make sure the 12v rail/rails have at least 50 amps flowing thru them

Id probably get at least a 1000w. Get OCZ's 1010w.

Go and get the rest of the system specs, how much it's going to be overclocked, etc. Then we can give you a more deffinite answer.

I'm 100% sure that he won't overclock anything. He likes it the way it is from the factory and won't ever do anything if it means taking a risk. As for the specs, he hasn't decided on anything yet, but his powersupply just went out on his old computer and instead of buying a temp one and then buying another good one that comes with the new computer, he was just going to buy one nice one to put in there now and when he gets the new one he would replace the existing powersupply in the new computer with the previous one that he just bought.

[erocker]

What about the monitor, and what resolution he uses? Are two 280gtx's really necessary? If he's not overclocking, the cards are most likely going to end up being bottlenecked.
