The FSP 300w supplementary PSU is useless, very low amps. You're better off buying a proper big PSU. 750-800W should be enough for 8800GT SLI. I'm using a Silverstone Olympia 1000W for my 8800GT SLI rig but u can check with Nvidia SLIzone site for recommended PSUs with minimum requirements. Mine is overkill for 8800GT SLI but then I always go overboard with my stuff anyways.

Go to Nvidia's site called SLIzone. They have a PSU recommendations thingy there. U can see exactly what PSUs have been certified for SLI usage by Nvidia according to which cards ur using.

It's already very good. Especially now that it does multiple screens set up which ppl have been asking for such a long time. Anyway, the guy's expectation of 100% improvement is unrealistic. 2 way sli scales about 50%. For 100% improvement u need 3 way sli.

Most of the big titles run SLI. The smaller titles that don't utilize SLI are mostly not very intensive n run fine on 1 card anyway.

Normal. U shud see mine lagi HOT!

Mine in Tri SLI goes up to about 100C under load, if I dont turn on the air cond. Idling itself is oredi at about 80C.

Yes stable. I use it for about 8 hours at those temps everyday.

My gfx cards PCB is memang black color. How to see darker color?

U better buy a 1000W PSU straight. Dont waste time buying small PSU if u intend to play high end SLI. Requirements will only keep increasing with the quad cores n bigger+more monstrous gfx cards coming.

U r using 1 gfx card only ler.
