Williams Pinball 2000 PK2 400W Power Supply ATX AT rear fan mount 230V / 115V. NOS - only opened to test prior to listing. Supplied with ATX to AT adapter. The green wire on the 20-pin connector is the "power on" wire, and it will need to be cut and grounded in order to boot the motherboard.
These are hard to find now with the rear fan mount. Power supply tester is not included and is only used to show working power supply.
