Corsair VX 450w PSU
 
It's available @ Buy.com for $56AR. Better deal out there?

Is this adequate for OC'ing a Q6660 and 4850?

That's a good price AR and yes it is definitely powerful enough.

Good price, good PSU. You're cutting it kind of close though, very little room for upgrade and the PSU rather close to the max. I'd rather get the 650TX from www.buy.com for $75.

of course it is good enough

Cool. Thanks!
