Dogie, so in other words, suppose I was using an antminer S3 , which has two boards and 4 pci-e slots... You could power one board, with one PSU, and the other board, with a different one? However, you could NOT power the same board from two different PSU's? Not that anyone would ever configure it that way, but that would be when you'd need the Add2PSU?

yes. The idea is that different PSUs may have slightly different readings or 12V and GND, and any differences caused by two PSUs on the same board can rely in the PSUs trying to equalize a large amount of 0.05-0.2V current through the hardware.

y_boonstra, that's good information on wire gauge. I don't have anything in front of me at the moment, but the info is duly noted. Thanks.
But on the non-modular power supplies, that didn't seem to be a problem for you, which is good news. It's reassuring that I know they'll work fine. Were those overclocked Ants? Granted, if they're not getting hot at 360, I doubt they'll be screwed at 400 watts.

non-modular is fine, but messier. A few zipties can easily tuck away extra length. remmber to link the PS-ON (green) and GND (black) pins on the mobo connector to allow the PSU to run without a motherboard.

IMO: most <$100 power supplies can handle 100-150W on a dedicated PCIe cable. Higher-end stuff (ie: gold rated and/or >$100) tends to be capable of 150-250W.
generally: 18awg: good for about 100-150W ----- 16awg: good for 200-300W (this is for entire 6-pin connector, not just a single strand)
