Yes. A good 650w PSU will handle this system nicely. What is your budget for the PSU?

I recommend Seasonic PSUs, as well as Corsair.

Sure you can, but not just ANY 650 watter. I would definitely get one that is at least Silver Certified, if not Gold Certified. But with the price of decent power supplies these days within $20-40, why not get one with more headroom. It's better if you get an 850W that runs at 55% capacity, rather than a 650W that runs at 75% capacity

I don't know much about psu.. but what's the difference between Silver Certified and Gold..quality?

Check this Seasonic out:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817151088

Note the special offer through 8/13

This is a GREAT PSU. Quiet, stable, and will last.

Also, if you want to spend a little less, here are a couple of other solid choices:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817151096

All of these will more than meet your power needs.

Here's your explanation
http://en.wikipedia.org/wiki/80_PLUS

and here's where you can check to see if a manufacturer has any units that meet certification

You can even get the Testing and Load Reports for a specific model... here is the one for the power supply I use

You don't need more than a 500-550W PSU unless you're planning on putting two HD6870s in that PC. I'd spend less on the PSU and upgrade the GPU to an HD6950 or GTX 560ti. Get the S12II-520 for ~$60: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151094&Tpk=s12ii-520 and that gives you $70 more for the GPU. Cut the case budget to $100 and that's $170 more for the GPU and would allow you to get an HD7850. Better performance and lower power consumption.

Edit: Your 6870 probably costs around $150-175. Add that to the $170 above and you can afford an HD7950...significantly better performance and can still be easily run on the Seasonic I linked. I use that PSU for a more power-hungry HD6950.

 

[Shinzo234]

Better performance?

2 GeForce GTX 560 Ti vs HD7950

depends, the 560ti(most likely 1 gb vram varient) will perform better till you hit games that use more than 1 gb of vram(battlefield 3) or bad sli configurations(arma 2). sli is more taxing on computer heat and requires a certified board as well as a lager psu requirement. a stronger single card will give you less issues than 2 stronger cards.

 

[Rugger]

That's the first time you mentioned an SLI of the 560ti. The PSU I mentioned is not sufficient for an SLI of 560ti's.
