I found this page very interesting

http://www.playtool.com/pages/psucro...ssloading.html

It says some PSU when drawing power from only the 12 V rail will shut down because
the 5 V rail can be out of spec (with no load). So a design with 4 Mini-ITX powered by
Y cables (to put a load on the 5 V rail) and any more ITX power by Pico PSU, might
make the PSU life easier.

The article looks a little dated, but the author sounds like they know their stuff.

Are you aware that such measuring devices are highly inaccurate?
Not true, e.g. the HP428B 1mA to 10A in 9(?) ranges, DC- 400Hz (3dB point), accuracy +/- 3% of full scale (circa 1970)
