Car Audio Amp Computer Power Supply Transformation
Channel: Dominic Gichane

In this video I converted my computer power supply to power my JEC3245 car Audio Amplifier. In addition I also connected an LED display and an optional 5Volts to a female USB cable extension for charging my power banks and smartphones.

For safety always use a fused cable with the ground connector working. Make sure that the chassis of the power supply is connected to the middle ground cable.

This is the colour coding on any power supply
Yellow: +12V, In my case
White: +12V too
Red: +5V I connected that to the USB cable
Orange: +3.3V
Black: Nrgative or Ground terminal
Blue: -12V
Purple: 5V SB (standby voltage)
Green: /PS_ON (short it to ground to start the Power supply)
So this is what the grey wire is for?
The grey "power good" indicator is at 5V if each of the output wires is operating at the correct voltages.
