Add for all of the systems the max power draw / system. (worst case). [ max memory, max rated CPU, max internal adapters of the heaviest load ]
Try to determine what is actually used when all are under load.
Then there is cooling: most of this power is converted into heat. You may need about the same amount in cool capacity ==> cooling equipment needs to be capabable of removing that.
There is a tendency to add more systems in the future (it's called growth) sometimes systems get more efficient... so don't calculate to narrow.

What is the maximum amount of POWER you can draw from your sockets?
Is this Domestic or Commercial ?
e.g. in the UK it's 13A per wall socket - that's 3,000 watts - so that's the maximum, without adding up any devices!
and then you've got earth leakage on every single device, which cannot be above 60mA or it will trip the RCD.

Find an electrician.
You are getting a lot of scattered data . . . typically, output wattage is also how you determine cooling needs and Input Current measured in Amps is how you determine power needs. For example, a Cisco 93108 with a 650-watt AC power supply will throw 650 watts and @ 1000 watts/hr you'd need about 3500 BTU/hr cooling. And that same box uses almost 4 Amps at 180-250 V AC at startup . . .so if you had 8 of those Cisco boxes you'd want 35 Amps to the rack . . . which is more than you'd need to run them, but not more than you'd need to start them up all at once.
How big is your room? Do you already have AC? How many devices are you plugging in? And so on . . .
Have fun!

Thanks
you can start making a list, adding the power numbers then
