As Analog said, his options are extremely limited.

To power a system with two 470s, it would probably require a quality 650W to 700W. But to power a system with two 6870s in it, a quality 550 to 600W (with a "continuous" rating) would be plenty.

The reason why I have the HX650 is because I wanted the HX450, but it wasn't available at the time. I like the way it looks.

Hey TwoCables, could I get away with X-fired 6970's with a Seasonic x650? Running an i5-2500k, 4 HD's and a bunch of case fans.

I think it would be enough. AMD recommends using at least a 550W "Peak" rated power supply to power a system with a single 6970 in it (proof), so I believe that it stands to reason that using a PSU like the X-650 would be plenty to power a system with two 6970s in it because not only is the X-650 the best 650W power supply available, but its 650W is a "Continuous" rating.

Plus, every single time I come across one of those AMD pages where they actually list the PSU recommendation to power a system with TWO of the said cards, it's always exactly 100W more than the single-card recommendation. So I bet that if they were to list it on the page I linked above, then they'd be recommending a 650W. But again, that's even including PSUs with a 650W "Peak" rating.
