Well, that's why I decided to keep my money and the Enermax. I will probably never go SLI, though it's not a totally impossible path. But I have a low power Opty and even when I do decide to get a new vid card, I still think I am way within my limits.

And I do not even classify a PSU in the same ballpark with a video card or cpu. Delivering clean, sufficient power is totally different than a video card being able to handle a new game or a cpu being able to keep up with todays software. My video card may not have hardware support for DX10 games, but my PSU has support for a card that can.
