So I'm confused.

Specs are in sig...

My power supply.

My issue is, it says it is ATX 12v 2.2 and EPS 12v. I'm running SLI and after reading the stickies it's not hard to figure out that the EPS 12v is not good but ATX 12v is good for SLI.

I'm running 2 8800GT's with C2D as you can see below with what I would consider an average OC for my CPU.

The problem I'm having is that when SLI is enabled my frame rates drop. And if I down clock my 8800GT KO, the framerates slightly improves and 3dmark06 improves when it is installed alone. This doesn't make any sense to me and when I call EVGA they ask me about the PSU and I tell them and they say I should be fine. But I'm afraid I have it running in EPS 12v instead of ATX 12v.

Can anyone look at the psu I have and tell me if it will be sufficient for SLI? I need to send the 2nd 8800gt back if it's not.

From what I read EPS just means that it has a 24-pin Motherboard connector and a 8pin vs 4pin for the CPU. So that should not be a problem.


Do your frames drop in all games or just 3dmark?

bingo

Make sure you have the 8pin connector hooked to your board and not the 4 pin

Frames in Crysis for example drop from 28-32 to 23-28 FPS....

PSU is just fine.

Problem is either with:
a) Drivers.
b) Crysis
c) Resolution/Settings
d) Card Itself.

Did you connect each graphics card to a different 12V circuit?
