How much power do I actually need?

post #1 of 8
Thread Starter 
I'm looking for a new PSU to downgrade my CM RPP 1.25kW to a modular unit, but I don't want to splurge. So, I am looking to be the most cost efficient and will only buy what I need in terms of wattage. How much does my sig rig need (+~100W for headroom and future upgrades/overclocks)?

Well,

You could run it on a 650w PSU, I'd probably go with a 750w just for a bit of headroom. That would allow for a number of heavy upgrades as well.

If you were running an SLi nvidia setup i'd probably say what i've got. Since it's ATI something like the antec truepower new 750 or the AX750 or soemthing. But that would be loads

Thanks for the response.

I'm thinking of getting what you got, the AX850.

It's a lovely PSU, I'm planning on having another GTX570 in here along with my GTX275 Physx card. This will also power a full custom loop at the end of the month

You could run all that on a SeaSonic 750w Unit at a push. 850W would be just right!

I'm running it off my CM RPP 850W now to do testing and there seem to be no problems even with 5GHz OC and OC on both GPUs. I'm thinking 850 is where it's at.
