I'm still on my original SNK issue power supply. Its 13 years old.

Try getting a surge protector for your NEO power supply, that could help. Power supplies HATE surges, especially switching power supplies like the one in the NEO power supply adaptor.

I would recommend that you keep the power supply unplugged when the system is not being used. Make sure you are using a good step down transformer.
