20 Pin ATX Extender for use with the PSU Converter. Install the PSU Converter directly into this in order to avoid splicing the power supply's wires. This also allows you to move your PSU Converter to another ATX power supply if needed. Please note that the plug on this extender is 20 pin, so it will only work with version 1.2-1.5 Xboxes with double-row plugs on the motherboard.
