850W enough to power this?

Okay, I'll soon be buying the following:
-- 2x Gigabyte 7970 3GB Overclocked @ 1000MHz each
-- Intel i5-3570k
-- Intel 520 Series 120GB SSD
-- Caviar Black WD 1TB 7200rpm Hard Drive
-- Corsair Vengeance CMZ8GX3M2A1600C8 8GB (2x4GB) DDR3
-- ASUS Xonar DGX
-- Pioneer DVR-220LBKS Black 24xDVDRW OEM

That's what it will be powering. Don't think I need to include the motherboard or anything else. Will it be able to handle it? Should I go to a 900W or 1050W PSU?

You only need a recommended 800w power supply for 2 x HD 7970s so an 850w unit will be fine.

Make sure to get a good unit. Stick with Corsair, Seasonic, PC Power and Cooling, XFX, Silverstone, Enermax, OCZ, Antec and the higher end Rosewill units.

Thanks for that. I'm getting a Corsair TX 850W.

An 850w PSU is overkill for that.
I run that and a 4.6GHz OC with a 650W, but i guess it depends on the PSU?

That XFX is excellent.

You are running 2 x HD 7970s and an overclocked CPU on 650 watts? You are cutting it close and likely are stressing that PSU to the dangerous limit.

Yeah I know Furmark. But still too close for comfort.

If you know how to do cable management, you won't care about it being modular. There's practically no difference, except for marketing purposes.... :p

There is an 850TX-M but it's a pretty low rated unit by Corsair standards and is also being replaced by an Chicony Power Technology made unit.

The CWT made 850TX-M. The newer Chicony Power Technology models are too new to have reviews.

I disagree. I have had both and will never buy another non modular unit again. This 750TX is a huge pain in the ass to manage.
