Im looking at converting an old ATX psu for use with a LiPo battery charger.
I'm testing it out at the moment, but it does not seem to be supplying 12v even with a load on the 5v line.
Its reading about 11.8 which is fine, but when I connect the charger and try to draw about 5-6A the voltage drops to below 10v which causes the charger to shutdown.
Now, I'm only pulling the current down one of the wires, but I don't think its a dual rail supply?
I could cut all the 12v wires and join them and see if that works but if it does not then its a total waste of the PSU.
By the way its a 300w unit, that says it should be able to supply 10A @12v
thanks
