Neo Geo home system power supply

I just picked up a Neo Geo home cart system off a local seller liquidating her collection. The system is loose and does not have the sticker on the back with the model number or power supply information. I took this pick and hopefully some one can help with what power supply I need to test if the console works. Many thanks in advance.

Get a DC 5v 3A negative 2.5mm x 5.5mm tip.

Thank you! Appreciate the help.
