If ya say so.....but DAMN I'd be scared.....

Ps.....How do you already have 3200 rep and not even have moved out yet??? I thought you were a "grown up", xD

What does my Rep count have to do with that?

Anyway, AMD recommends a 650W peak-rated power supply to power a system that has two 6970s in it. Any quality, recommendable 650W power supply will be a continuous-rated unit which means that any recommendable 650W PSU will have a much larger capacity than any 650 peak-rated unit.

On top of that, the 460 would be pulling a very small amount of power since all it would be doing is processing PhysX. So most of the time, it would just be sitting there doing nothing.

A quality 750W unit would be much more than enough. I'll post some really good 750W units that don't cost more than $200 after shipping.

OP, how many video cards are you planning to have?

If I am reading the OP correctly, you want to power:

- two (2) AMD HD 6970's
- one (1) Nvidia GTX 460 for PhysX

A high quality 850W could run that at moderate overclocks. Now if you overclock the 6970's with +20% PowerTune, a 1000W PSU is what I would suggest you are a gamer.

According to Phaedrus' PSU calculator, your rig would need 900W (includes watercooling and +20% PowerTune and additional voltage).

Basically pick any 900-1000W PSU in your budget from this list of recommended PSUs: http://www.overclock.net/power-suppl...-supplies.html

Well it seems like it would take a while to get all that rep.....

Ok, I'm down with 650w for 6970s. But the GTX 460 has a TDP of 160w, so I would think you need an 800w minimum. This is of course assuming everything at 100% load, 100% of the time. I can see how it's not realistic to load everything at once, but isn't it just smart to assume the "worst case" scenario?
