The 4 pin 12v connector was introduced with the P4, after your PSu was

I was under the impression that the additional connector not only
provided more power but isolated power and ground planes for the CPU.

I don't think it isolates ground and power might depend on
the board. Some past boards would potentially run, albeit
with the potential for instability, with only the 20-pin
connector attached. Other boards won't, definitely must
have 12 in at the 4 pin connector.
