A high capacity PS is always good to have, esp. in a high uptime
box.  Having that extra wattage available can prevent power dips
from making things flake out.

Doubtful, BUT, Power Management has always been a sore spot for
me, I've had millions of Win PCs croak when they try to "wake"
from their low power mode.  I blame the variety of specs, and
variety of BIOS, motherboard, disk, etc. manufacturers.  In short,
I'd avoid "power down when idle" and similar, if this is a
production machine.
