I *AM* going to install a Quantum LPS-52 SCSI drive
inside my Mac+.  The drive says 6 watts.  It is a low
profile, low power consumption drive.  My question is
do I really have to spend $50 for a seperate 20 watt
power supply for the drive?

Or if I upgrade my Mac+ power supply (install new various
components as per Larry Pina's "Macintosh Repair Secrets..."
suggestions), and adjust the voltages with the drive
installed, will *THIS* work?

Just what are the Mac+'s power supply ratings?  Someone
told me that if I install a drive like this, there is a
significant drain particularly on startup.  The drain,
so I was told, is enough to possibly cause the drive to
trash itself during startup.  I don't want this!  :^o

What do people think?
