I really like the idea of the split power cable but which mobo controls the power switch?

If you turn one mobo on, does the other one turns on as well?

Yeah, those are cool.

I think it would work out that way which wouldn't be too good. Isn't one of the 20 pins used to switch on/off the power supply? If it is, you could probably just cut the wire so that the motherboard can't control the PSU, but it seems odd that they wouldn't do whatever needs to be done for you.

Yes onewillturn both off
If I remember right it is the 4th pin on the other side of the clasp A RED wire check it first before cutting it
I think you can get this info or check it from you MB speck book

When you turn the power supply on, both come up.
When you turn it off, they both are off.
This is for rack/shelf computing, no cases, BIOS set to start when power returns. ;)
Now if you had say 5 PS and 10 mobos and those were plugged into one power strip, a single switch could control it, and it might look something like this :D

TeeJay made all of the splitters by hand for me (before they had such things on the market) :thumbs:
PCZ and Bok helped me build the *nix Server. These were diskless nodes :)

Actually, it's the single green wire that controls power. You can run an ATX power supply without a motherboard by shorting the green wire to ground (the black wire next to it.)

Here's one of a number of sites that explains the colors, wire gauges, and connectors:

I'd also like to point out that the cable that is shown for sale there is only 6" long - which is going to cause you some difficulties with two boards that are side by side - in most instances, that's going to be about 3" too short. I even had some troubles when trying to use splitters that were 9" long. These would work with additional extensions, or if you were mounting the boards vertically, face to face.

At $21.50 each with shipping, I would consider these as kind of expensive.

Yeah and for $21 you could do it yourself and probably have some fancy control to do the split so that 1 psu supplies to boards with independent on/off (hmm wonder where I've heard that before) oh yeah I thought of it ages ago lol..
