How much power?

It all depends on how much room for expansion you're looking for. I personally have a cooler master extreme 600w and wish I had something that I could do more with. I mean, the wattage is great but there are just not enough connections in the right categories to constitute a good power supply for a nice gaming system.

I would suggest something modular and high-wattage, because you are going to eventually have to upgrade and things will constantly demand more power and connections to keep up with the gaming community, and PSU units are relatively low range in price to wattage. It's nothing like graphics cards' exponential increase of price with minimal differentiation in results.

But if you need to stick to a budget, the minimum wattage for that system would be fine, but you HAVE TO make sure that its going to support everything you need. I bought a radeon 4850 not knowing my PSU didn't have a pic power connector, and I had to watch it sitting in that bag for weeks.

I can't stress enough that checking what can support what is the most important aspect of choosing a PSU. I can say this from experience.

Please keep us updated with what you choose, and thanks for hearing me out!

using this, pulls under 400. Skimping out on the PSU is a good way to lose all of your goodies. Most important but underrated component. You don't need high wattage but higher quality.

500 watt version but you can pick up the 430 version as well if you really don't care.

If you've got the cash, skip the CX and go straight for the TX - Corsair TX 650 v2.

I'd go for an 850 watt PSU, it gives you more cables to work with and the extra power will allow for excessive use of CD/DVD drives, espcially if you intend on burning lots of disks.

Don't forget that you may be thinking about attaching extra devices to usb ports or may need to add a another hdd in the future, best to have alittle more power than running at full steam all of the time.

thanks for all the help. What exactly is the difference between the corsair tx and cx series?

CX is built using less quality parts TX V2 is built by Seasonic the CX is built by CWT if you want to learn more about it check these links http://www.realhardtechx.com/index_archivos/Page541.htm and this one http://www.eggxpert.com/forums/permalink/323050/323050/...
