Hi - Where are you located and what's your budget?
I'll assume 2 hdd & 3 case fans, & stock cooler, but you might
want to add after mkt cooling if you are going to CF

Great - that PSU is more than enough amps/watts and
a very good choice. You are good to go.

Thanks for the replies,

My budget was 80 cnd im from canada. I will take a look at those cases and concider i was leaning towards the inwin because of its price (99 cnd) and the good air flow plus usb 3.0.

Is 750w really necessarry? If i dont xfire right away? Can i get away with a 500w or am i pushing it?

A good 500w PSU would work now. But when you xfire you will have to spend more money.

It's cheaper to buy one PSU now, than have to end up paying for two.

For a system using a single reference design Radeon HD 7850 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 27 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

For a system using two reference design Radeon HD 7850 graphics cards in 2-way CrossFireX mode AMD specifies a minimum of an 600 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 39 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.
