Protection Features, Evaluated
Check out our PSUs 101 article to learn more about PSU protection features.
Our protection features evaluation methodology is described in detail here.
Protection Features | |
---|---|
OCP | 12V: - 5V: 32.5 A (130%) 3.3V: 32 A (128%) 5VSB: 5.8 A (193.3%), 78.48 mV Ripple |
OPP | 762.51 W (117.3%) |
OTP | Yes (125°C @ Secondary Side) |
SCP | 12V: Yes 5V: Yes 3.3V: Yes 5VSB: Yes -12V: Yes |
PWR_OK | Proper operation |
NLO | Yes |
SIP | Surge: MOV Inrush: NTC Thermistor & Diode |
Over-current protection on the minor rails seems to be properly configured, while at 5VSB it should be set at a lower level to prevent ripple from getting out of control. The over-power protection's triggering point is set at a reasonable level, while OTP is configured quite high. Finally, there is SCP on all rails, the power-good signal operates properly, and besides surge protection there is also protection against large inrush currents. It would be ideal if there was a bypass relay as well, but we're probably asking for too much from a Bronze-rated PSU.

turkey3_scratch Onus why would Corsair produce me?Reply
Anyway I think the price/performance page shows all. This thing rocks!
Also Jonnyguru claims it is a rifle bearing fan that has the same model # as the sleeve variant. -
benedict78 Does the CX650 perform the same as the CX650M? I'm not interested in modularity anyway.Reply -
Aris_Mp I have several CM and CX-M units, which I plan to fully evaluate. So far I figured that there are differences (something natural of course) in their performance.Reply -
Dark Lord of Tech Could you put the newer CXM 750W OR 850W on deck soon , as they are widely use for DUAL CARD configurations.Reply -
turkey3_scratch The 750W and 850W CXM units are basically unchanged except for a bridge rectifier upgrade. Everything else is the same. Only the CX450-650M got the major revisions.Reply -
Dark Lord of Tech Yeah I know that , but want to see one reviewed , to compare top older generations.Reply
