On S100 bus power supplies, unless you are extremely energy conscious it’s easier to supply S100 bus motherboards with 8V and 16V switching power supplies rather than 5V & 12V and pulling each and every voltage regulator on every S100 board. A suggested source is here:-
there are countless others. I would also be careful getting a “cheap” 5V unit. If the is a glitch to a higher voltage, there goes each and every board in your S100 box if you don’t have a V regulator on each board.

I have noticed several folks are using the Meanwell QP-200F PSU, recently. I looked it up, and it is a bit expensive, but it appears to be much smaller than my current 8/16vdc pair of units. I assume that the unit can be adjusted for the proper voltages? Do folks who have them think they're worth the money?
