all power is supplied via the bussboard...dont use an extra psu etc...just use a ATX or AT psu to supply the whole amiga ..
or else u might end up frying your setup ...
just read the manual and be 100% aware of what u are doing (atleast on the power side...)
good luck and congratz with yer new setup!
(i bought the same back some years but i replaced it with an mediator due to many reasons, but the main one was SPEED..)
cheers
