Will this 500W power supply power the 512mb 8800gts?

[blazer78]

Not sure if this is the right place to post it but I have a FSP AX500-A (Fortunetec) with ratings of:

# DC output:500W
# Max A output:12V1:15A, 12V2:16A

http://www.fsp-group.com/engli...nid=1&fid=52&proid=135

Now I've read that the 8800gts requires 26A on the 12V rail as a recommendation for power.

Since I have dual 12V rails both supplying ~15A each, does that mean my power supply wont cut it for a
single 8800gts? (Since the 8800gt only requires one 6-pin connector)

My other system specs are as follows:

Pentium D 830 @ 3ghz
2x DVD-RW drives
2x 7200RPM HDD
2GB DDR2 533 ram

Thanks in Advance

Its 26A total for combined 12V rails for a GTS, the 8800GT requires a good bit less than that, like 20-22A I believe. You should be OK but if things get flaky you'll know that's a potential problem. I ran a 640MB GTS on a TrueBlue 480W and it was *barely* enough with an E2140 @ 3.0GHz. I had to unplug all but one optical drive and could only use 1 HDD or it wouldn't POST (loud single beep, ie. no video card detected).

hmm.. how on earth can this power supply be "SLI-Ready" then?

(The box has the nvidia sli-ready logo on it)

Most benchmarks of single-card GTS-512 systems maxed loaded total system power at less than 300W. The card itself seems to draw about 160W± loaded.

You should be fine. It isn't the most efficient card ever, but with 31 amps on the 12 volt you'll be fine.
