Crosair CS550m any good?

Solution
The NEW CX psus probably are, the OLD CX units not so much.

The 430, 500, 600, and 750w are old.

The 450, 550, and 650w are new.
Nope, the CSM series are poor value for their relatively meh quality and not so great voltage regulation.
The new CXM series are better value if you're looking for a new power supply. (Black label version, not green)
The CXM 550w is currently 49 bucks at newegg after a rebate and is a steal: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139147&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-PCPartPicker,%20LLC-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=

 


That's not exactly a shining endorsement. 😉
