My prior firewire enclosure worked fine with only bus power right up until I
zapped my machine. After that, the problems began.

I've been using a usb powered hub and get the same result. My firewire card
is also molex powered as well but I remember just buying that card about a
month before the zap, worked fine bus powered with my other enclosure before
zap and didn't afterwards. I used the prior laptop drive mini enclosure for
about 6 months before the zap so I know that this machine can power them
fine bus powered. The 'Q' is, why not now after it was zapped?
My PS doesn't get hot to the touch for what that's worth.

I'm having a little trouble remembering but now I vaguely remember that when
I swapped between machines, I 'may' have not switched over entirely. Thing
is I may have only switched over the PS to my present machine, that or I
tried a few different scenarios but my point is, now I don't remember if I
am using 'all' of the whole new box. Could have swapped back my PS too?
Yeah, worthless info. :)
I would definitely prefer to bring my s900 back up to par instead of moving
over everything to the beige anyhow as my primary. Especially since I have
two s900's here to work with. It's very possible that my mobo got zapped
and is telling the PS to not send as much power to the various components so
I may just put everything into the other tower and see what happens. I do
believe a few things did get zapped back then, after all, it did assassinate
the drive.
I'd say 100% that my firewire card was also somewhat damaged if were not for
the fact that this brand new usb card also doesn't quite get enough power to
the drive. So it's probably a reduced amount of power getting to the
components, the question is Why? (OF course that doesn't mean my FW card
isn't damaged some too) So today I'll first try disconnecting a few things,
see how that goes, and if no change I'll swap machines over entirely.
Also looks like all the Smalldog $7 Power Supplies are gone so if that's the
culprit I'll have to find one elsewhere as well but we'll rule it out first.
Thanks Will,

Yes, the $7.00 Power supplies are long gone. They only had them in stock about 7 years ;-). Sorry no ones getting my spare ;-) We're lucky our very own Jeff W came up with a way to use standard PC supplies. You could check your power supply with a voltage meter while it's running to see what the output is. Just test one of the spare hard drive power cables. The two black should both be ground and the red and yellow...I think one is 12 volt and the other 5 volt. Jeff or some one will know for sure.I'd watch to see if you get a big drop in voltage when you switch on the USB or firewire drives or if the voltage varies in general more then say 1 volt + or - . If it does then your power supply is failing.
