Sega Blast City + J-Pac *PSU Question

[jvlk]

Hello all,

Got a question about the psu in a Japanese blast city.

According to the ultimarc website

Most cabinet power supplies will not function unless a game board is connected, owing to insufficient load. It is best to remove the power supply completely as the J-PAC does not need any power. All power comes from the keyboard or USB interface. The monitor power must be left as it is though. DO NOT remove the monitor isolating transformer if one is fitted.

Than I see a post from Andy (Ultimarc), and i quote

"Maybe I have over-emphasised this issue on the J-PAC pages. Ken L is correct most PSUs will not be damaged with no load. Its really only very early switch-mode supplies which have this problem, when the designers had not yet got them right. They usually would make a high-speed clicking sound before blowing.
The current J-PAC is also pretty bomb-proof against being plugged in backwards as it has zener diodes on all the inputs which end up being conencted to an incorrect voltage if this happens.


So my question is, can I leave everything as it is and just hook up the j-pac and don't remove the psu?

Yes.
