Can anyone give me a link to corsair cx550 new grey model. I have searched everywhere but can't find any. I want to know hold up time and the main cap. Used in it.
The CX and CXm units are ok as a budget option, but I do not recommend pairing them with gaming cards. The newer 2017 models of CX and CXm are better than the older ones, but still not what we'd call terrific. Even so, in a real financial pinch, or if there are simply no other good models available to you, then the GRAY label Corsair CX and CXM units are passable. You would be wise to avoid the GREEN label models.
Aside from that, any of the TX, RM, RMx, RMi, HX, HXi, AX or AXi units are good. Those are listed from good to best, with the best of these Corsair models being the AX and AXi units.
