upgrade PSU for xfire setup

[corei5]

am looking for new PSU for my future 5870 xfire setup my current PSU isd 700W OCZ modular and it is not enough to set up xfire .

thank you.

That is more than enough for crossfire.

i tried to calculate it though and it need more than 700W to add another 5870

 

[gurusan]

nah it should be fine

 

[corei5]

I calculated 2x 5870, 2x 2GB RAM, HDD 7200rpm and dvd-rw = 773W needed.

What do you mean you calculated? What did you use to calculate? What are your calculations? Because they are wrong...

 

[patonb]

those psu calculators over estimate things... I run 2 260s at 100% on a 700W.

i used newegg psu configurator

 

[james.wired]

ahh...Newegg's calculator is not very accurate to say the least

 

[corei5]
