Powering an 9800GX2 SLI Rig

Computer_Freak · 04-11-2008, 02:37 PM

ok well my dad is going to the states and Im gonna get a GX2 (its the same price as a GTS here :p)

Now, in my later stage i will SLI 2 together. How much power will be needed (With a CPU 4 gigs or ram etc)

will a 800W Gigabyte Odin work with 2 9800GX2 in SLI + a new Quad core + a better mobo etc.

Cause i saw the 850W silverstone Strider in greece and it costs R1750 there and the Gigabyte Odin 800W costs R2000 along with the Coolermaster RealPower Pro Modular 850W. (R = Rand)

so will 50 watts make a differece in that setup?

how much will i need

At least a 1200w or better psu. Make sure you pay attention to the volts on the rails or rail, and it would help to get a known brand.

1200 watt plus for sli, i think the 800 would do you for the 1 gx2 but thats about it as far as power recommendations go

what!!!!!!!!!

never. in review sites thay say you can do one with a 500W but they recomend at least a 600W (the say system draw is about 400W)

1200W, well that does it i ain getting no GX2.

What about a 9800GTX rig?

You don't need 1200W, don't listen to those people. You actually only need 584W under full load, but to be on the safe side I would go with a 750W+ PSU, in case you decide to overclock or add more components.

I came to that conclusion using the Q9300, 2x DDR2 Modules, 2x 9800GX2's in SLI, 2 SATA Drives, 2x DVD-Burners, 4x 120mm fans, 1x PCI Card, and under 100% load.

if this is the case, then why do some people buy 1000W PSU's? that is way over the needed power

^^ They have their reasons.
