Why?

The CX is SIGNIFICANTLY BETTER than the CV.  Only the efficiency is the same.

 

The CV is an older double forward topology with group regulation.  It's essentially the VS platform with some upgrades to hit Bronze efficiency.

 

The CX is LLC with DC to DC for the +3.3V and +5V.

 

Also, the CV has a sleeve bearing fan.  The CX has a rifle bearing fan.

 

EDIT:  CV650 is the exception.  It's still double forward, but it has DC to DC for the +3.3V and +5V.
