500w power supply enough for SLI??
Last response: in Graphics & Displays
I currently have one eVGA 7800GT on an sli board. I was considering in the future(month or so) to add a 2nd 7800gt card to run in sli. However I just purchased a new power supply and was wondering if 500w is enough power to run the sli config. If its not then I will probably just wait because I am doing fine with just a single 7800gt. However, I would like to get some more fps with some of the games I play.
Also, I was wondering how much performance increase you get with an sli setup? Reading other posts/reviews it seems mixed. I saw some where you only got 4-5 more fps then hearing from other people its closer to 40-50% increase.
*I run dual 20.1 monitors.....do I lose fps having both enabled when I run a game?

Xbit have an article on the amount of current the different GPUs draw, the 7800GT is very efficent ![:)]( ":)")
As long as it's a quality PSU then I don't see any problems. I think nVidia recommends a 550W (but also states the current requirement), i'm using a TypeR 480W which exceedes the current requirments. I have been running the system for about a month without any beeps, crashes or any other unexpected behaviour. System is as follows:
A64 3500+, 4x512Mb Corsair Cas 2 DDR400, Asus AN8-32 SLI
2x 7800GT 450MHz (stock)
1x80Gb & 2x120Gb Maxtor 7800RPM HD
Sony DVD & LG CD-RW
Philips Acoustic Edge sound card
3x system fans in CoolerMaster aluminium chassis
