of the 410 watt redundant power supplies out right now as it's not
need yet and saves the curent draw from 12 amps down to 8, making the
18 AWG cable safe since I heated ina groove with a soldering iron and
then trimmed the melted flash off t he sides of the groove.
Actually, since these are switching supplies that are wired in parallel,
pulling one power supply won't change the max current draw. Adding or
removing drives and boards would change the max current draw. With two
power supplies handling the load instead of three, the two just end up
taking more of the distributed load. The 12A current draw I imagine is the
max inrush rating, not what the unit would normally draw. HP would have
come up with this rating by completely loading the system with the max
boards, drives and memory that could be added, checking the inrush current
draw, then adding some safety margin to that. You really should check the
systems present current draw with an amp meter, however.
