Using both power supply's

Hi

 Simple question, does using both power supply's cause double the power load, so if i am using 355 watts does that mean both PSU's are using 355 watts so i am using over 700 watts? or does it only use 1-5 watts as standby? i have two breakers where the system is but ultimatly on the same Main line.

 

Thanks

Re: Using both power supply's

Since one power supply is usually for redundancy, you don't consume more power with more power supplies. Depends on the system itself, but normally 1 PSU provides power to the system, the second is more or less in standby.

Hope this helps!

Re: Using both power supply's

Power Supplies are rated to deliver a safe maximum amount of energy, rated in Watts. There's a lot of intelligence built into HP's power supplies, read up on the below link!

They usually load balance across the number of power supplies. Not all PSU's are created equal!
