I have just finished a Gigabit to ATX mod, might posed pics if I fined a camera.
Wile I was looking around for info on a ATX power supple mod I found that people where
using 24v external supple for the 28v that the Gigabit mobo needs to boot.
So I thought, what is the lower limit for this supple and still get a boot. I then hooked up my
bench top supple to the 28v line of the mobo. I stated at 24v and got a boot, then took the voltage
down in 5v steeps, in-till I get to 5v and still got a boot.
I then used the 5vSB line (purple) on the ATX supply that is not used by the mobo, for the 28v supple on
the Gigabit mobo.
My mac has been running with this setup for the last two days, I will post if I run into any problems.
The system is a Duel 450 MHz Gigabit with 1.5G of ram.
I hope this info is useful to somebody.
