Determining power requirements for server & etc...

[Deleted member 12106]

We are in the process of adding an additional server at work. I had placed the order today for everything, then, realized...

Do I have enough power? I do not know what breaker the gear is on now, or, how big the breaker is...

But, off the top of my head we will have:
2x dell sc440 servers
-core duo cpu's
-4gb ram
1 runs a sas controller/drive
1x dell PowerEdge t100
-core 2 duo
-4gb ram
2x internal hard drives
3 switches, router, modem, 3 1500va battery backups, kvm...

This gear is in an office with 2 other people, that have each their own computers, plus there are 4 printers also going.

Now, I am figuring a solid 10-15amps just for the server stuff. The breaker box is not far away, I am thinking just have a 20a outlet dropped directly behind the servers.

Is a 20a going to be enough? Anything else I should consider?

IBM actually has a power calculator, as does APC.

See if either of those helps, both get pretty darn specific.
