Take a look at the bottom left of that case, and the psu its running.

For the records its running

HOW MUCH POWER do you actually need to run two water-cooled Socket 1207 CPUs at 3.0 GHz each, two overclocked Nvidia GeForce 8800GTS graphics cards, 150GB Raptor drive and 4GB of memory clocked at a fast 1GHz PC2-8000 clock?

That system should be drawing 685W at peak load, and the PSU does it fine.

I'm only running a 510w on my system that theoretically should require more but it's a quality, efficient PSU.

Aside from my sig, I'm running another HDD, TV tuner card, 5 fans and several USB items from a hub that's not independently powered. I'm also pumping 1.58v into my Opty.

I don't think efficiency is the right word... It's just using the right parts... Corsair keeps on doing something that other companies don't do and that is start at the top and work the way down... Their XMS line took off and then they worked done and made a solid value series when it comes to memory and the same is holding true for Power Supplies and Water Coolers.
