First cable for Euler Bus power done!

The trouble with atx power supplies is that they often have a substantial minimum current draw (can be as high as 3-5 amps) or they don't work properly. A fully loaded Pine board would be on the low side of that. The reason for this is that most atx power supplies are switching supplies capable of delivering 5.1 volts regulated at fifteen or more amps -- so they are optimized for the expected high current draw... a low current load like the Pine board may not be adequate to meet the minimum current specs of the atx supply. Most of the time folks that use atx supplies for bench supplies need to fabricate a minimum dummy load -- and of course that can be done in the case of the pine board too.
