Just use the black and yellow for 12 volts -IF- the power supply is already powering a motherboard. If not then don't use that supply. Not worth the time and power draw to properly load the 5 volt side.

I dont know about that...i have many fans and lighting and water cooling accessories on my hobbie machines that's molex connectors only feed of one line and i have psus going on 3 years with no issues...i still dont see where to attach the 12v line on the MT board though..
I do not have a MT connected to a pc psu but i do have pc PSU set up for power to other equipment and power banks.
I use just the 12v side quite often. I have the 5v side open for use and leds to show the voltage status of each line. The only thing I had to do to make them work without a pc was load the logic line off 5vdc so it would power on when the main switch was turned on and I put a resistor on the 12v side to make sure there was always a load on it because pc psus are stepping transformers.
I would have to look but it should be center pin is + and the yellow wire is +.
Normally center is positive. I would check it though by using a multimeter on the current power connector. Dont solder it into the mikrotik though, just put a connector on the wires so you can plug it in. Then it can be used on a poe injector bank or on a box it self.
