Do you have a picture at more of an angle? Which model is this?
Also, if you have to ask how many phases, it sounds like you read on a forum somewhere that 12 phases or whatever is the best. Honestly, don't listen to that. The kids making it sound like you need a certain number of them couldn't even explain to you the electrophysical properties behind a choke, what a mosfet is, or how the VRM system is designed.
But if you insist, give us the model or post a better picture.
