mATX Build PSU

[Aemon]

I'm looking to build a mATX system primarily as a media centre PC/Blu Ray player with some light gaming support. I'm pretty sure i'm going AMD route X3 720 Black edition. I've already purchased the case a P180 Mini

Initially its just going to be a system with onboard graphics but my aim is to increase the graphics capabilites as time goes on.

The problem is I don't have a clue about which PSU to fit. I'm thinking Corsair but I want to future proof it a bit so unsure whether to go with the HX650w or HX850w. How are these in terms of power usage?

Advice please?

Thanks

Anthing around 650w + will be more than enough for the future...But a OCZ Modxtreem 500w will do the job perfectly now if your wanting to stay with onboard

Corsair TX 650w are really good units and will run pretty much any single card configuration on the market.
