I'm running the standard 135 Watt PSU on my 3000 and have 4 Zorro
cards, 2 HDDs, 1 cd rom, HD FDD, CS060 plugged in with no ill effect
on the power. I have had 2 more HDDs and another cd and a cd-r
plugged into this system as well in the past, probably pushing the PSU
to the point I would not have added anything else :-) You should not
have a problem with your PSU.
