I have a Crossfire question. (GPU Crossfire, not the game.)

[VP :3]

Ok, so I wanna buy a 2nd AMD Radeon HD 6850 to Crossfire them. I have a 700W PSU ATX12V V2.2 / EPS12V, but I want to know if I need a bigger PSU to handle a Crossfire. Like if I need to step it up yo 1000W. Can anybody answer?

assuming your PSU is of decent quality, it is way more than enough.

EDIT: yea, you are definetly fine

Yea....6850s don't draw much power

~127W TDP, and my rig uses probably ~325W under max load.

~127W TDP, and my rig uses probably ~325W under max load.

maybe in furmark+P95.

I would say typical usage is much lower

under max load
So yeah, furmark + P95. lol.

 

[reflex99]

furmark not really a realistic max load thpiug

 

[Ph?bus]

Max load is when everything is at 100%. How isn't that a realistic max load?

 

[reflex99]

because nothing will ever push it that far >.>

 

[Ph?bus]

I guess you don't know the meaning of max load. It's not a good representation of a game load or average load, because that's not what a max load is. Herp derp.

as i would add from my personall experience:

Don't push your PSU to the limit. If you have for example 500 Watt and your entire system uses 490, it's most likely going to break faster then u have 750 Watt and your system uses 490. don't push it to the limits, buy big enough for more options later to!
