So long story short, I've got plans for a large system that would require three 1500 W power supplies, for a total of 4500 watts. Problem is, I can't plug all of these PSUs into one outlet in my room, because it would exceed the amp rating of the entire circuit. To keep things safely balanced, my idea is to cut a length of cable from a 50m spool I have, and wire it to another circuit, which would be two adjacent rooms. Stick a male plug on one end, and make an external socket housing on the other end to plug the PSUs in to (basically, build an extension cable).
Now, I've had computers in the past that run multiple power supplies. As long as the individual hardware are only receiving power from one of the power supplies, there is no danger of electrical damage. For example, power some hard drives with one PSU, while the mobo is powered by another. However, there are a couple of unique situations for what I am currently building, which forces me into uncharted territory.
Firstly, if I have one PSU powering some video cards, while another PSU powers the CPU, mobo, and RAM, will this be an issue? Since the mobo is able to supply some power from the PCI-e slot, I'm not sure if this will be an issue that gives the same results as powering one piece of hardware with two PSUs.
The second issue is on the AC end of things. Different circuits in a house will have different phases, so it's highly unlikely that I will have all three sources of power in phase with each other. I'm not sure if this would affect the DC side of things.
I have a feeling that both of these issues aren't a problem, but just for peace of mind, I'd like to hear some input.
