Power consumption of pyramid

Hi im planning a live eurorack right now and i want to power the pyramid via a FH-1.

my eurorack psu is capable of 1200ma and i allready use 507ma on the +12V and 456ma on -12V.
how much ma does pyramid draw from my psu.
im thinking of changing my psu to a stronger one with 5v /-12v/+12v and 2000ma.

has anyone experiences, with powering thepyramid by FH-1 without the 5v?

I had trouble with my Shuttle Control + Pyramid when I was using it as a PSU. Ostensibly a Pyramid should only need 500ma, but it definitely draws significantly more than that on boot.
