Modded PC power supply for charging

[BrianG]

BL_Maxx:

No. If you hook your charger across the +12v and -12v leads, you'll have 24v and at low current (the -12v rail is rated for low current). Use the yellows (+12v) and equal number of black wires (ground). All the rest of the wires aren't being used. The only exception is the green "power-on" wire, and maybe a red & black and/or orange & black pairs in case one or both need to be loaded with resistors.
