Star Castle - just dug it out to start the repairs --?s

So I got a star Castle a while ago, boards were locked on red led, so I knew that was bad, sent them off for repair and there were several issues, mostly failing roms, sockets, and a processor, plus more, now they are good... dug it out of storage to get her going (picked up a few extra DAC chips by accident for the monitor, but its in an unknown condition at this time..)

My Question, I want to test the power supply without a load on it, i.e. boards not hooked up, I remember testing the thing before with the boards on, and got 5v but couldnt remember if the game needed anything else to run, and didnt test, so.... can I test this sucker without a load on it? I dont want to fudge the new boards but cant remember if that is kosher or not, I seem to remember an issue with those supplies (circuit breakers were one, mine seem good)...cant remember other issues with these.. anything else I need to know before I test??
 
Also, stumbled across a NPT power supply for these games, put it aside my Condor to show the differences, found the NPT in a pile of rubble at an ops place...literally rubble...
