Default 1 Power Supply / 2 Motherboards

Anyone have any experience running two boards off one PSU? I had initially ruled this out, but after seeing this listing ( http://www.ebay.com/itm/251040286517 ) which it seems would keep me from the hassle of splicing wires, I'm now considering it again. Both boards have their own CPU, and are dedicated prime hunting machines. It occurred to me that a power off signal from one board may turn power off to both, but since both systems would normally just be chugging away 24/7, I don't see that as a problem.

Both systems together only draw about 160 watts (total) and it's a 430w rated PSU.

Anyone with experience in this area know if I'm just asking for trouble, or should it just be this simple?

It's doable but at 83% you're running that psu a little high.

The 160w is both setups together (about 70w on one, and 90 on the other).

These types of cables should be available at a Micro Center store, if one is convenient.

This issue is why the "George's dream machine build" thread uses a PicoPSU to power each board.
