Default PSU's for SLI

Is there a list or website for PSU's that will
drive 2x260core216 vs 3x260core216?

Example: Will the corsair 1000w do 2 cards?
Can it do 3 or do you need something bigger?

If you run 260's or 280's,
What's your psu?
What do you recommend?

Thanks.

We have a list; http://www.techist.com/forums/f76/re...-guide-137927/ You will only need 850W for tri sili 1kw is overkill except in extreme situations. My psu is a Bfg ES-850W its a goodun comes with lifetime warranty and got great reviews. If your going with sli 260's get an I7 build and the Evga 260 core 216 they are much cheaper then the 280 but nearly the same performance wise

I didn't see anything in that thread about
what power supplies would power two or
three gtx 260's.

I took advise here and got a EVGA gtx 260 core 216.
It's great and is fine with my PSU, but I would like to
know what is needed if I want to get another card.

So how many amps do you need
to run 2 or 3 of those cards?

I was looking at Antec NeoPower 650W and then
started looking at Antec TruePower Quattro 850W.

Is the 650 for 1 card and the 850 for 2?

no I would say 650W was good enough for 2 cards but just and to be comfortable for future upgrade e.g. an I7 build, the 800W+ is warranted

Go for the i920 and 2x gtx 260s with the 850W Antec.

Tri-SLI won't do much for you unless you are gaming at some insane resolution or just love benchmarking.

As said you need a 30" monitor to appreciate trisli something like 2560x**** redolution. Little point getting the 940 as the 920 is a good overclocker and with the money saved you can get a good heatsink for it or a watercooling loop. Get the 850W antec quattro. What case are you putting this in???

Thanks.

The 920 does sound good.

I also think 2 cards will
be plenty for my 24".

I was thinking antec 900.
