I have an old 450 watt PSU from a computer that specs at 14 amp on the +12 volt line. I want to use it to power some battery chargers. I ground the green wire to turn on the supply, and hooked the yellow +12 and ground to the charger, (which draws 2 amp), but the PSU won't handle it. My charger reports low voltage, (it drops to 10.5 volts as the charger ramps up). I don't understand why this would be? I tried two different supplies and they both act the same.
Thanks in advance!
