Had a similar problem with a PE 610 -- had to buy a larger power supply.

I upgraded some firmware for the iDRAC and all of a sudden my
system didn't have enough power for it's config.  Was forced to upgrade 
supply from dual 540's to dual 870's...

System still only uses in the mid-low 200's, but about 30W more with
the less efficient, higher capacity power supply.
