Re: [vox-tech] power supply

[Mark Kim <mkkim@ucdavis.eMAPSdu>]

Why am *I* supposed to know this? :P

Yes, yes, splitter's fine (the concept of it, that is).  The load on
Pete's system is quite a bit, however, so I suggest 300W or
higher (higher moreso than 300).  Consider skipping the CD-ROM if you have
CDRW -- CD-to-CD copy is not a good idea anyway.

I try to use the following rules when I install a splitter -- but I
don't know whether it works or not since I don't know what it looks
like inside the power supply:  When splitting, try to split between
devices that won't be (or at least not likely to be) used together, like a
CD-ROM drive and a floppy drive, or a Jaz drive and a floppy drive.  Try
to give the HDs their own power lines since they always spin whether you
access them or not (unless you set them to spin down after X minutes of
inaccess...)  Some CD drives will spin forever after you stop accessing it
-- keep that in mind.
