Why not go with 3 PSUs? For $60 you can get something like
Corsair CX500, which will easily power a single ant, even an overclocked one.
Cables, and How would i go about setting each one up? Im running these in my garage which only has two outlets (2 plugs, not two sets of two) but that's it, so I have the whole circuit to myself xD. I don't really want 1500w running through a power strip..... I also need the other plug for ethernet over power bridges. SO yeah, how should I go about doing this?
