[j-nsp] EX4550 true power consumption

[Michael Loftis]

I don't know anyone that assumes that the peak capability of a PSU
(especially in network gear) is it's actual consumtion, but thats just
me.  I do agree I wish they'd publish at least approximate figures.
It can be a deciding factor in a lot of environments today.  Keep in
mined 650W is high-line mode (~220/240VAC) - in 120V it's only going
to be around 325W.
