9800GX2 PSU

[manithewindlord]

Hello,

I just bought a 9800GX2 and i am completely lost in struggle for finding a cheap PSU.
I MIGHT go for a 9800GX2 SLI sometime in future and i cant find a PSU which offers 2 x 8 pin and 2 x 6 pin pci-e connectorsor even one with 4 x 6 pin pci-e that i can convert to 8 pin by using a converter.
I am using asus P5N32-E sli plus+E6600+4GB ocz ram.

i am a bit tight on budget so lookin for the cheapest possible solution.

How cheap is cheap to you?

well, the minimum recommend PSU for the GeForce 9800 GX2 is 580 watts. and for two GeForce 9800 GX2 cards, nvidia recommend a minimum PSU of 850 watts.

here is a list of recommended PSu's for this GPU:

i am looking for something around 60 quid...give or take a fiver.
i see that i can find 800W or even 900W PSU in that price but they all have problems with the connectors they offer.
If i am not wrong one 9800GX2 requires 1 x 8 pin and 1 x 6 pin connector which would mean i need two of each? .

why ? 50-65 is impossible? whats the minimum in the realms of possibility ?

a bit more budget friendly

either one will run your 9800GX2 just fine and just about any other video card out there. I would avoid any cheap 700-800w unit, they are simply garbage and rarely provide the power stated on their box.

if you want to run two 9800GX2, I would strongly suggest you increase your budget.

cheers mate...I really appreciate the help and advice , you are a rock-star.

I think I better avoid the hassle of buying another power supply later on and take a bit more heavy hit now and have a peace of mind.
how much should I stretch for running two 9800GX2 ?

each card pulls 198w so I would look at a decent 750w unit. the card also runs hot, just an FYI

antec, corsair, enermax, silverstone, ocz, seasonic, xfx are just some of the brands that offer reliable units.

here is a nice budget option

what about the rail design ? 850watt in typical rail design will hold 198+198w ?
