What's the maximum number of IDE (UltraDMA 100/133) drives that I can
safely power from a ATX power supply (assuming that you have enough
IDE/UDMA connectors of course)?

I have an old PIII system (Abit BH6) in an ATX case that currently has
3 UltraDMA 100/133 hard drives connected to a Promise UltraDMA 133
controller card. And I am wondering if it's OK to add a 4th such HD in
there without running into any power supply issues.

I am not sure what the wattage is of the power supply in the case but
it is an ATX case. This system does not have an optical drive and the 3
HDs connected to the Promise controller card are only ones in there
presently.

Thanks.
