Am I right in thinking that neither of the 2 above mentioned PS would work?
Wouldnt I need a PS at least 15.2 amps?
I dont have any motors yet, just trying to figure out what will work.

It depends on the drive. Assuming your'e using the bipolar Xylotex, the drive has a max output of 2.5a, but due to the way chopper drives work, you'll never need more than about 2/3 of that for each motor, usually even less than that. Just figure on 2/3 of 2.5, x4 which is around 6.6. The 6.5a supply above should be fine.
