Anyone have any tips on suitable PSU's for jamma/MVS cards from these sellers ? (as I'm ordering some other stuff so would be nice to combine it in a shipment):
Mean Well RT-65A
Mean Well RT-85A
Mean Well RT-125A
If your games don't require -5 V, then you could go for the Meanwell "RD" series:
Mean Well RD-65A (if you're only going to use the MVS/CPS2/PGM and other more "recent" PCBs, then this option should be enough)
Mean Well RD-85A
Mean Well RD-125A
Unavailable in the stores you listed (and difficult to obtain these days), but really decent:
