A solution for powering 12v stuff inside
I came up with an idea for a little board that you can plug into an ATX AC-DC power supply and get the full rated current out of it for powering 12 volt stuff inside while your configuring your car computer and stuff.
Just about everyone has a Cheapo ATX power supply lying around, or can open up their case and borrow it for a while. Most of these put out more than 10 amps at 12 volts. This ATX Breakout board will control the ATX power supply, show little LEDs on all the supply rails and power good, and bring out the power connections to standard automotive blade connectors.
Works like a charm for powering my computer.
