I tried to use an atx psu on the indigo2... and it works. Until a certain point.
I connected only one wire per voltage rail so it can be undersized.

When i start the psu the led turn green, the jingle is played and then the led becomes orange. Then the screen Indigo 2 silicon graphics appear. Then the system make a noisy click, like a relay, and reboot. Sometimes i managed to get in the prom monitor. I got some errors:

Keyboard error, then i connected a keyboard.
Unable to boot. Touch any key... touched a key it rebooted

One time i had time to get to the prom and it seem to function normally.

Voltahe are a bit low. 5v is 4.7 - 4.8 volts i think the psu is cheap, i dont know if this is the the problem.

Toughts ?
