OK... my Dynamo JAMMA cab's huge ass ATX style (but larger) power supply died...
The PS has the AC plug going in the back and two sets of lines coming out ...one set of lines goes to a harness where the +5 +12 etc go... the other harness just appears to be an AC pass-thru harness that powers the ISO and the marquee lamp.
The PS died... and I am replacing it with a switcher that I have on hand (will be powering a 1xxx-in-1 along with the ATX PS that the 1xxx-in-1 comes with)... however the AC line still goes through the old PS to to power the ISO and marquee lamp... I'd like to just leave the setup as is... leaving the bad PS in using only the AC line ... and then using a new switcher for the +5, etc...
Will that old bad PS be "burning up" even though there is nothing connected to the "DC" lines? One thing I noticed the PS did when it died... the 12v line died so the fan doesn't work on the PS... I worry that may be a problem, though if there is no load, there shouldn't be much heat generation, right?
EDIT: I'm so dumb I can't spell "DUMB"...
