Which one do you think looks the best, and which do you think performs better?

Are there models in this list you would not recommend, and why is that?

The question is your thoughts on looks better and also what you think in just terms of what you think has better performance.

Agreed!

Why in the world do you need a 1200watt PSU?

Even sli/crossfire of the most power humgry cards don't need more that the PC P&C silencer 750.

i love my Silverstone 1200watt. I've never had any problems out of it, and it's an 80% unit good for up to 1000watt output.

You are using 78% of the PSU's capacity on idle? That's scary...

Of those listed, I'd pick the Turbo-Cool. Expensive, but worth it for a rig like yours.

Edit: Just curious: what motherboard did you get, and are you using a RAID card or the onboard RAID?

perhaps you could just get a smaller dedicated one for the gpu's as that would reduce some of the load.

Toughpower 1200W Power Supply is what I run and it's nearly silent with excellent reviews. It exceeds the efficiency rating according to independent testers. I don't even think many of the others were out when looking.

When Thermaltake comes out with the 2000W PSU I am probably going to consider buying it. I still have thoughts 1200W of power even at 87% efficiency will not be enough power for future upgrades that I have in plan. I don't care if my electricity bill goes up more, not that important to me.



When I do go for freon I am thinking I will also put these on my 2 Radeon 4870 X2 for cooling.
