Corsair TX-850 Questions:

[itsbighead]

Hi Community

I know this is the same as my other thread but I am building a new Gaming PC. The specifications to it are as followed. Will a Corsair TX 850W be able to support 6970 CrossFire X along with my other hardware i want to get or do i need to get a different PSU?

CPU: Intel i7 2600
Memory: 2x4GB Kit G.Skill Ripjaws-X DDR3-1600
Motherboard: Asus P8Z68-V Pro
HDD: WD Caviar Green 1TB
Graphics: 2x HIS ATI Radeon 6970 2GB CrossfireX
PSU: Corsair TX-850W
DVD: LG SATA DVD Burner

Well the specs http://www.hisdigital.com/un/product2-577.shtml for the card say a 550 Watt PS is needed. So for 2 cards (which will never pull the max when in x-fire) I'd say you need a 1000 Watt PS with 4 PCI-E connectors. Something like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139034

but then ive also heard people on the forums state that they got a 6970 CF with just a 850W?

I'm just going by the specs.

hmmmmm

hmmmmm indeed. Not sure what to advise you. If people are pulling it off with an 850 watt PSU, and you can verify it, then I say go for it. If you can't verify it though, I'd rather be on the safe side.

lets have a look at what the gurus think?

You might want to start a new thread asking this specific question. Just a thought.

 

[itsbighead]

i think its ok, as long as people take a look at it

The 850TX is more than enough for 2x 6970 in CF. Even on water you wouldn't be able to overclock them to the point that they'd be drawing enough power to strain the 850TX.

EDIT:You could run them off a TX750, or any other quality 750w PSU.
