Corsair CX500M

Is this power supply any good?  It's on sale on newegg for $34 after MIR and the psu in my old desktop is dead.  That system has a Q6600 and 8800GT.  Will be building a new PC soon as well, will be a mATX build with a 3570K (or haswell equivalent) and a GTX 780/770.  Will not SLI.


Or would I be better off with the CX600M for $50 after MIR?

What about it?
