How much do I need?

[bh31]

Hi all,

I would love some advice on what PSU I should by, here is what my PC will look like

EVGA 780i
Intel Q6600
8800 GTS 512 x2 SLI
2GB of Corsair Dominator 8500
4 hard drives
Scythe S-Flex 120mm fan for CPU and 4 other case fans
DVD Writer

I was thinking of 3 PSU's
- OCZ GameXStream 850W ATX12V 24PIN SLI Ready Active PFC ATX Power Supply 120MM fan
- Thermaltake Toughpower 850W ATX 12V V2.2 Quad SLI Ready Power Supply Modular Cables 140MM Active PFC
- Thermaltake Toughpower 1200W ATX12V 20/24PIN Quad SLI Modular Power Supply Active PFC 8PIN PCI-E

I don't really know if 850 would be enough so I'm hoping someone here could lend me a hand. The reason I jumped over the Thermaltake 1000w PSU was because it's only $6 more for the 1200w.

I think that sums it up.

Thanks!

I like Ultra X3s, totally modular. I have a similar system on a 600W. Adding a second video card shouldn't kill you.

550-600 would be good. The PC P&C 750 would also be good to look at. Little extra power should you need it next generation...

A good 500w psu would be more than enough for that system.

my personal favorite: Corsair 520HX. Its a dream to work with and has 40amps on the 12v rail.. hell of a lot more than you need

My first PSU was an ultra.... HEADACHE

I will never ever buy another ultra product again.

Ultra X3 isn't made by Ultra, just has their name on it.

Agreed. The Corsair 520HX is one of the BEST PSU for under a $100, and some times even better than $100+ PSUs.

Dont care, I have absolutely no faith in that company (ultra that is)

I know why you would say that.

But if I ruled out every company I have ever had a problem with their equipment I wouldn't be buying a single computer.

Every company has their problems and quirks at some point.

The Thermaltake toughpower 700 or 750 will be more than enough for that system

Thanks for all the replies you guys have save me some $$$ I'll most likely end up going with either the OCZ 700 or the PC 750 quad.
