HP Proliant DL380 G7 power calculation

Question

HP Proliant DL380 G7 in year of production has alternative PSU:

750W in "performance" configurations with 2 CPU

460W in "base" and "entry" with 1 CPU

"Power advisor" calculator is not accesible in 2017

My question is:

Can 460W PSU work with 2 middle range CPU (80W nominal power), limited number of 2,5' HDD, 24GB-64GB RAM and no extra controllers?

EDIT: machine for internal projects, sometimes will be down, 24/7 is not required

Answer 1

The ILO will tell you how much power is being used.

But if you need a reference, here's what current statistics look like on a system with the following specifications:

2 x Intel(R) Xeon(R) X5680  @ 3.33GHz
64GB RAM
4 x 10k SAS disks
4 x SATA SSD
