Hi all, pretty new to this. Just wired a computer power supply sock can charge my rc batteries. However it will only produce 11v on the 12v wires. I have a 10w 10ohm resister on the 5v to produce a load, and apparently this will help raise the voltage on the 12v side of things. At 11 volts I get a low voltage error on my charger. How can I get it to 12 or a little more? Thanks!!!!

Try a larger load. Your load is only 500mA, or 2.5W -- not really a lot for a PC power supply.

It's hard to say. Try loading the 5V rail first. If that doesn't help, try loading the 3,3V rail.

Essentially... Do whatever works.
