Obviously I would never run both at the same time I know that won't work, but if say the Naomi power cable was unplugged could I make the pc still turn on ?

edit: looking about also would it not be possible to use a sata power port to power up the naomi, it has the 3.3v 12v and 5v lines. Then I could have both powered up at once ??

It's not just the voltage you need to worry about, but also how much current each line will deliver.

IIRC the Naomi PSU has quite a large 3.3v supply (15A or so) and I doubt very much a SATA connector will have the oomph to power the Naomi mobo.

I tried to make a supergun run from a HDD power cable, and ended up fooking the PSU.

Great tutorial just thought I would say that from my experience it is easier and quicker to remove the atx connector using a heat gun. :smt020
