This high-quality, hand-crimped power cable will allow you to use your ATX power supply to power your Sega JVS Type 1, 1.5, 2 or 3 I/O pcbs. It uses one of the standard 4-pin molex connectors that would normally power a HDD in a PC to power your Sega I/O. The other ends terminate in a 4-pin NH connector for 5v and a 5-pin NH connector for 12v. These are the proper connectors Sega used to power the I/Os. Standard cable length is 40cm.

Price will be $25
This adapter is made to plug directly into the third 8-pin power connector most SUN PSUs have. It's very convenient to avoid multiple PSUs for your Sega setup.
