Put a paper clip (or any join) between the green wire and any of the
black wires on an ATX power supply main lead to power it up without a
motherboard - google "power up atx supply without motherboard" if you
don't trust me<br>

<pre wrap=""> I have over a half-dozen different SATA hard drives, each with
different data (configs, voiceprompts, voicemail, CDRs, AGIs) for each
one's different user groups and applications. Each one's load on the
Asterisk server is small enough that one server can host them all,
accessed easily over USB.
But right now, each one is in its own external USB enclosure on a
powered USB hub. I want to combine them all into a single large
enclosure. I tried to use a single PC chassis, leaving the USB hub
inside with the drives screwed into it, and powered from the PC power
supply as internal drives on the proper drive power output plugs. But
without a PC motherboard plugged into the power supply, too, the power
supply won't start up to power the drives.
I don't want to add a motherboard: that costs money, and sucks power,
and is totally unnecessary. I just want to make this gutted PC chassis
power my drives only, and have them connect to the complete PC sitting
next to it via the single USB cable coming out of the drive chassis. How
do I do that?
Is it possible to use the extra, unused floppy power plugs to power
more hard drives, with an adapter? Is it possible to split the existing
hard drive power plugs to each power multiple drives? How many drives
can I split each power plug into? The power supply is a cheap 300W unit,
and the drives draw max under 9W each:

25-30 of these drives, or at least 10?

<pre wrap="">Is the reason for separate drives security or something else? How
much data will the max size drive hold?
Maybe a few of these could solve your problem?

Looking for a JBOD SATA enclosure with six slots but they are way expensive.

The drives are 750GB drives, each one a different related set of apps
from a different Asterisk machine. I've consolidated them all into a
single Asterisk server. And I already have the existing PC chassis and
power supply, as well as the $10 each SATA/USB adapters. If I can just
figure out how to power them from the PC power supply without plugging
in a useless motherboard, I'll have it done without spending any money
(other than whatever cheap part tells the power supply to run without a
mobo).
