This JAMMA power supply from Min Dong is excellent build quailty. The brand name is debossed into the metal case, which is an attractive dark navy blue.

Please Note: Despite still labelling these PSU as having a -5V 1A output on both the front of the PSU and on the label on the side, these PSU now DO NOT supply -5V. Min Dong seem to have removed this functionality and didn't think to mention it or change the case or label! To be clear, the components to supply -5V are not present within the PSU at all.

A large amount of games do not use -5V so these PSU will be suitable, however some games do rely upon -5V, particularly older games, so please do check before hand to ensure you do not need -5V prior to purchase. If in doubt, ask on one of the friendly arcade forums.
