Power supply suitable for 8800GTX ?

[GeoffW]

Hi

I would value a second opinion please as to whether my power supply could handle an 8800GTX card

CPU = Core 2 Duo
2 Hard Disks, 1 CD Rom, 2 or 3 case fans

Power Supply is an Enermax 485 W

Thanks for any help

it should be, but i wouldn't be overclocking anything. it has 32 amps on 12v rails combined, and the 8800 takes up 30 of those. if your planning on overclocking your system, i'd get a psu with a little more head room..

With its 32A on the combined +12vrails that will be plenty to power a basic system and the 8800 GTX

agreed, just dont go and overclock it to the max (e.g. volt mod etc.) 8)

Thanks for the replies guys. I had come to a similar conclusion that it was borderline OK.

I can barely justify the cost of the very expensive 8800GTX as it is. If I had to stump up another £80 or so for a new power supply it would have to get shelved.

Regarding the overclocking comments, were you referring to OC'ing the Video board or the CPU or both ?

I wouldnt want to OC the 8800 but I do usually run with a small CPU overclock.

well, the cpu doesn't use the 12v rail (i dont think? i know my psu does but thats because its a different design than standard..) so cpu overclocking is ok, and im sure that the graphics card will be able to handle a small one too. if the computer starts acting up after you overclock, the most likely culprit is the psu. good luck

Overall any OCing has a draw effect on the overall performance, and lifespan of the PSU, so, if you are doing any OCing you are still loading the PSU down to some degree or another, as to which rail, etc, that is just one circuit in a system of many.
