650w is a little low for two 6970's + a GTX 460 if you'll be overclocking. Those power control settings in CCC with increase consumption by quite alot.

750-800w should be fine.

A high quality 850W could run that at moderate overclocks. Now if you overclock the 6970's with +20% PowerTune, an 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

wrong.

More than 750w is overkill.

this one is nice. plenty of power. likely more than you need, but a psu with the connectors you need at 650w will be harder to find.

That's very different. It's very different with PSUs because of how they work. When you're using a PSU that's "just right", then you are getting the highest efficiency possible from it. If you had a quality 1000W powering your system, then you'd be getting a lower efficiency and probably even stability problems due to the extremely tiny load on it. That's right: some PSUs don't do well with tiny loads like that.

Please try to trust me: a quality 750w is about perfect for your upgrade plans. All of the PSUs I recommended have such a large capacity that you'll never max them out.

But hey man, it's your money so do what you want. However, you came here asking for help, I'm trying to give you what you came here for, but yet you won't listen.

Carlos, don't you think starting off with "wrong." is a bit rude?

If I remember correctly, the Silent Pro is more or less just a mediocre PSU. Sure, it's one of Cooler Master's better units, but it still pales in comparison when considering the superior PSUs that can be had for the same price with basically the same capacity.

Some people ask for help while having no idea that they actually don't want any help; they just want everyone to tell them to do what they have already decided to do (and many of these people don't even realize it).

During my 2½ years here, I've become accustomed to people asking for help and then shooting everyone down regardless of what the community thinks of those who helped.

good choice
this power supply is one of the best quality / price
your PC with high-end crossfire, physx card, liquid cooling system, overclocked X6 needs a serious power supply...and if it is slightly oversized is not a problem...means that it works so cool and quiet
the contrary would be a problem

I recommend a 1000W power supply for this system.

Why? AMD recommends a 550W peak-rated PSU to power a system that has one 6970 in it, so they would likely recommend a 650-750W peak-rated unit to power a system that has two 6970s.

So I don't understand: the GTX 460 as a PhysX card wouldn't pull that much power, would it?
