Agreed. They are better than they used to be, but I still wouldn't use a CX model. Corsair has great higher end units, but the CX series is still inferior to other units available.
The power being supplied isn't the problem. The problem is that the power supply uses inferior components that are more prone to failing than many power supplies you can get for the same price, such as a unit from Seasonic or Antec.
