Calculate Total Power (Watts)

[Anonymous user]

Hi all,

I will ask you for a little help.


We want to buy a UPS device. We have servers with redundant power supply and I do not know how to calculate Total Power (Watts). I do not know whether the server uses the power of two power inputs or just one input supply. For example if the server has 2 x 1200W standard hot-plug, optional redundant power supplies with dual power inputs, for UPS capacity (Total Power) whether to collect 2 x 1200 = 2400W or just 1200W?

Can you recommend any literature where these things are explained?

Thanks in advance

Hi kkxenon,

Can you provide the brand/make & model of those servers?Most often that not, the manufacturers have the average power draw of the server listed in their tech specs.

I hope this helps.
