Hello Roland,
I think your problem are the disks that never go in sleep mode
Your cpu requires about 35W (from hp specs) , the disks should require about 0.7A@12V x 4 disks = 33.6W (from internet). So you reach the total power consumption you stated
@phillxnet wrote a detailed post about sleep mode, I think it will solve your problem:
Bye the way, this is my first post in the forum, so hi all
