It is a bit hard to specify power ratings in computer power supplies, as
there's several of them.  A 300 Watt supply might well be able to supply
enough current on the 12 Volt rail, but not on the 5 Volt rail, for
example.  You need to check all the supplies, but then they don't always
list things that way, nor do the products your powering usually list
their requirements.

Your drive might specify how many Amps it needs for both the 12 and 5
Volt supplies.  Your supply needs to be able to provide for them, at the
very least, plus whatever else is in the box.  That's the harder part,
many things don't mention their needs.

I have a PC using just a 90 Watt power supply.  It has on board video
and sound, 500 MHz Celeron processor, floppy and hard drives, and a DVD
burner.  It all works fine.  Yep, ninety watts.  It flies in the face of
various power supply calculators.
