Which PSU and drivers do I need ?

Seems you are over complicating stuff. Its very simple to make and connect, see picture.

You need 2x50VAC 500W transformer, 10000µf 100VDC CAPACITOR and 100V 15A or more bridge rectifier

Buy the stuff and people here on the forum will help you make it. Obviously the schematic is super simple.

Hallelujia, I now understand ! I am quite amazed by the fact that it's so simple ^^.... Thanks also to Clive for providing the links :) Now that I understand how easy it is, I feel much more comfortable making it myself !

While I am writing this I am looking for the parts you provided on AliExpress instead of Ebay (don't have an ebay account, neither a paypal account, and I don't plan on making one :p.. I have taken a great pleasure at buying stuff on AliExpress :D Those chinese guys can be amazing :D ! Got 2x2m SFU2010 + 1x1.3m SFU1610 + 1x0.5m SFU1605 + end supports + couplers + free shipping for 340 Euros !

I still have unknown areas:
1. How am I going to connect this to the wall, taking into consideration that I am using 220VAC (does that even matter ?)
2. How am I going to connect all my AM882 to the board ? All in parallel ?
