Complete newbie here, first post too. Can someone please direct me to a wiring diagram showing how to power two 12v meanwell power supplies from the same power cord? I purchased a pre-built Falcon F16v4 controller box with only 1 power supply for all 16 outputs, and wish to add another power supply so that each power supply has only 8 outputs to power.

Hello and welcome. I'm also new here, but i did just that. I connected PSU 1 with the neutral, live, and ground to the same on PSU 2 and PSU 2 out to the single plug-in cable. But make sure you put a ground wire (V-) between the both supplies. I got the idea from Ni Family Lights who is amazing on power distribution and pretty much anything power injection and other stuff.
Check out his video here. He uses a receiver build but shows how the 2 PSU's are wired together. I've done it and works great!!

jumping on this thread. How do you know which wire gauge to use when connecting PS to controllers?
A rough guide to current carrying capacity is 10 Amps per 1 square mm. So a 2.5mm (cross sectional area, not diameter) wire can carry about 25 Amps.
This works well for shorter distances, but beware of voltage drop on longer runs. For 240V power losing a few volts over a 10m run is no big deal, but at low voltages the voltage drop is a significant portion of the supply voltage. So long runs at low voltage can require cables that are much larger than just the required current capacity.

and this is why transmission lines are very high voltage. the higher the voltage, the lower the % of the power you are losing.
