Hey Guys,

I am about to upgrade my machine in the next day or two and need to decide on a PSU, preferably a fully modular one and with enough headroom for further upgrades to come.

Specs:
MOBO: Gigabyte GA-X58A-UD3R
CPU: i7 930 @ 3.36 (Will be further OC'ed)
RAM: Corsair 6GB DDR3 1600 (3x 2gb)
CASE: Antec Nine Hundred Two V3 Case (4x Case Fans)
HDD: 3x WD Caviar Black Drives
SSD: 2x SSD's - OCZ Vertex 3 and another old one I cant remember the brand of
MONITORS: 3x Samsung S24A450BW 24in Widescreen LED Monitor
GPU: 2x MSI Radeon HD6950 2GB Twin Frozr III PE/OC
COOLER: Corsair H80

Other than that I run a few components off of USB, I have been looking at around the 850watt mark and found this PSU: http://www.pccasegear.com/index.php?main_page=product_i... (Australian price)

A) Will a good 850watt PSU be enough
B) is the Antec TruePower Quattro 850W TPQ-850 a good PSU, or is there better for the money?

Thanks for your help.
Cheers,
Nick

You can use a quality 750W no problem for your set-up.
According to guru3d a 650W would work.
So an 850W is unnecessary imo.

Good 750W psu's push out over 900W no problem.

Thanks mate, definately looks like a good PSU and appreciate the suggestion.

Will see if anyone else has some recommendations but so long as there is enough power for my setup and is modular then I am happy, especially if I save some dough at the same time.

After looking around a little more thanks to the recommendation below, I actually stumbled upon the Corsair HX-750 Power Supply which I think I will go with. Looks like a great PSU!
