Cross-Load Tests And Infrared Images
Our cross-load tests are described in detail here.
To generate the following charts, we set our loaders to auto mode through our custom-made software before trying more than 25,000 possible load combinations with the +12V, 5V, and 3.3V rails. The load regulation deviations in each of the charts below were calculated by taking the nominal values of the rails (12V, 5V, and 3.3V) as point zero.
Load Regulation Charts
For a Bronze-class power supply, the efficiency graph is pretty good. In the 90 to 590W region, efficiency is higher than 85%. That's 100% satisfactory for a PSU that costs $65. If you need higher efficiency, you'll have to spend more for an 80 PLUS Gold or Platinum model. Or, if you're prepared to pay a premium for Titanium-class efficiency, consider Seasonic's Prime 650W model.
Toward the end of the cross-load tests, we took some photos of the PSU with our modified FLIR E4 camera that delivers 320x240 IR resolution (76,800 pixels).
The temperature levels inside the CX650M are much lower than we expected. Obviously the thermal loads are lower than other Bronze-rated PSUs and the cooling fan does a pretty good job.

Thanks for the review on this new CXM platform.Reply
Looks to be better then the old CX line up.Reply
Good to see that Corsair didn't produce a Turkey with this one.Reply
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.
Does the CX650 perform the same as the CX650M? I'm not interested in modularity anyway.Reply
The CX650 is not out yet.Reply
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
Could you put the newer CXM 750W OR 850W on deck soon , as they are widely use for DUAL CARD configurations.Reply
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
Yeah I know that , but want to see one reviewed , to compare top older generations.Reply
