so in order to determine what wires are connected to which rails i can look up the specs on the back of the psu, is it possible that the wires may be color-coded to indicate which rails they belong to?

i just bought a 4 12v rail (19A each) power supply, HEC Zephyr 750w

The wires are not color coded like that. Most power supplies can dynamically select a rail based on load.
