Theoretically not but what exactly is the model name of your PSU?

That is why I do not trust CM power supplies even if I like their cases & coolers...

itd be really tight with the 460. not really enough wattage on the PCI-e rail output. a 550w is barely enough with no headroom for anything else. id think the minimum should be a 600w. corsair, silverstone, seasonic would be some strong choices.

Seriously 600W? Modern PCs consume much less power than most people think. Example: http://www.silentpcreview.com/article1245-page3.html
A system with a 2500K and an HD 6870 consumed 271W at full load.

2Fast: Is your CM Elite Power 460W enough? Yes but it is a very low-quality 400W PSU with a liar-label claiming it is a 460W. At high loads the PSU has excessive noise and ripple and these conditions damage components. I recommend getting a quality PSU to replace your Elite Power PSU...it ain't so elite.

your understanding of how much power PC hardware draws is very poor

at load he would just barely break 300w (if that since the i7-920 draws more power) total power and during gaming he would be well under the mark

to answer the OP question, yest the CM PSU will work but I would start saving for a better unit sooner rather then later.

Which one I would like a 550 watt so I have room for expansion?

Is 550 enough or should I get a 700 to be safe and be able to make more future upgrades, ie water cooling secound 6870,etc.

If you want a second HD6870 down the line you might as well go with a bigger unit. 600watts will do it but you will need 4 PCIe power connectors which from most manufacturers means 750watts.

Internally, we can see that the Core Edition 550W uses the Seasonic S12II platform, very much like the Core Edition 450W. Even the fan is identical:

it's built by seasonic using their S12II design platform but parts come from other companies. it's like when a Chinese factory makes a TV for samsung using part from various Taiwanese vendors for internal parts.

more then enough, you won't break 300w gaming with an AMD 6870

Yes it is plenty 500watts is what is recommended by manufacturers and people run the HD6870 of Corsair CX430.
