How much power?

[wolfram23]

Hello,
I'm about to upgrade my pc. First thing on the agenda is a Radeon 5850 and a new PSU. However, in perhaps a couple months I intend to also get an i5 750 CPU with an ASUS P7H57D-V EVO motherboard and probably 6BG DDR3 RAM. I'm wondering what PSU I should use as I'm fairly new to all this. At the moment I'm looking at possibly OCZ ModXStream Pro OCZ500MXSP 500W ATX12V V2.2 / EPS12V SLI Certified CrossFire Ready 80 PLUS Certified Modular Active PFC Power Supply compatible with core i7 - Retail link here. Will this be sufficient for everything?

Yes it will be. Don't expect to be able to upgrade to crossfire or anything like that though.

Thanks! Crossfire would be so far down the road I won't worry about it for now.
