Difference between Corsair's CM and CXM PSUs?

I have a couple of questions about Corsairs CM and CXM PSUs. I've heard that CM series power supplies are badly made and shouldn't be put in higher end gaming PCs, If this is true, are the CXM power supplies just as bad? Because when I compare them they seem near identical. They're both +80 bronze, semi modular, in the same price range, etc.

I have a couple of questions about Corsairs CM

There is no CM psu. There is the CX series and the CX- M means its semi modular. All the old ones have a non and semi modular model.

CX430

CX430M

One of the major differences is that the old ones are rated for 100,000 hours operating at 30C. You can check corsair site for this information. So this is one of the biggest issue "heat", which if you are stressing, overclocking, then the psu will not last its rated time as it will be operating over 30C. The price as you could buy a much better psu for similar or less.

The newer ones (2015 edition all semi modular) use better components and are rated for 100,000 hours at 40C.

This is the review for the older CX750M
