Having the PSU only output 12V does nothing but move the point of failure to a more expensive component, raise the cost of the motherboard and make it more of a pain to replace when a VRM goes bad.
I also just ran into the issue you were describing, with regards to the modular power connectors. Since I had neglected to label the modular cables with the make/model of the power supply from which they had come, when I ended up needing to use the modular cable to add a device to a system, there was no indication of which modular cable would be OK to use and which one would result in magic smoke, since none of my modular cables agreed on a pinout (6 pins in a 2x3 plug matrix), yet all fit into the same modular socket on the power supply.
On one connector the upper-left wire is 5V and on another that same connector position is Ground.
On another set of cables that also fit, the upper right is +12V, and on another cable (again both fitting the same plug socket), that position is not connected.
You would think the PSU manufacturers would jointly agree on a spec for modular cables (maybe somthing similar to the molex 4 pin, but with an added pin or two to carry 3.3V for SATA.
