This power supply kit provides both 5 and 12 volts for your games mods from the included Mean Well power supply to get the strain off of your games power board. It comes with both the standard Stern 3 pin and Bally/Williams 4 pin connectors to work with most mods on the market. It also provides a shared ground so your ColorDMD will also plug right into it without issue. Your mods will be turned off when the machine is turned off as well. It comes with plugs to work with Stern (pre-Spike), Sega, Bally/Williams WPC and WPC-95 systems. Please contact us if you need a Data East connector and it will be provided. No tools required, installs in 5 minutes.
