I would recommend an HX750 or HX850 PSU. Or something similar from XFX / Antec / Seasonic.

Overkill. you could run your system on a 750w easy.
Probably, but it means i have some spare power if i want to add things smile.gif

You can add ALOT of "things" to that psu smile.gif you could run 2-3 rigs off that single psu lol.

PLENTY! I have been using Mushkin PSU's and have had very good luck with them. Next gen Amd/Nvidia GPU's are supposed to be even lower power than the 6x series, so you will have lots of headroom when you upgrade from your 6950's.

I run a similar system (in terms of power draw). My 750w handles it like a champ.

My Kill-A-Watt claims to be pulling over 700w from the wall with everything fully loaded.
650w would suffice should the whole system not be fully loaded, but do I believe you or the meter plugged into my outlet?

You learn how to interpret the data from the Wattmeter wink.gif
Power supplies are rated at output not input.. your DA750 offers an average efficiency of about 80%, as so you'll need to see ~940W at the outlet for your PSU to be fully loaded(750W output)

Since your Kill-A-Watt measures 700W from the wall you can easily calculate your actual draw(based on efficiency) somewhere around 560W wink.gif

the Antec 900W High Current Gamer is actually a 850watt on 12volt rails and the 5v rails has the other 50watts out of the 900w

Nope, doesn't work that way. An ATX12V power supply doesn't have to provide all of its power on the +12V. It just needs to provide about 80-90% of it on the +12V. Which the HCG does.
