Oh and thanks for the B-P-P hint. I forgot all about them. Wish mike carried the 250w hyperion and the adapter. Now i imagine i could possibly run both chargers off of a 500w 2 x 20a 12v rails. One charger on each rail. Only bringing this up because i already have one of these laying around. If this will not work you guys suggest at least 15a for each charger???? Or could i go less or have to go higher. Not sure how to figure out what i need to look for in the PSU. A formula to figure out a min would be great. thanks again guys. As usual you were all very very helpful.
