Hi,
We have 6 Dell PowerEdge T430 servers with 2 750W PSU on each server (one connected to the wall socket and one to a UPS system)
What is the best way to calculate my UPS needs?
I’ve checked in a few vendors automated calculators and each one gave me a different result.
I do know the basics about Amps, Volts, and Watts but can not figure out how to do this calculation.
Thanks in advance. I appreciate your help : - )

APC has a good UPS selector. If you don’t want APC, you can at least figure out what model of theirs is most suitable and pick a competing brand with the same ratings.
I would recommend two separate UPS units - one for each power supply.

For some reason it won’t let me proceed when I dump your servers into the configurator. And, it seems to want to throw you immediately into the monster datacenter UPS units when I try other methods of using it. An off day at their site maybe?
What kind of budget do you have (ballpark figures), and what is the minimum runtime you are seeking?
I have a simple question which is: I have a UPS which is EATON 9130 and as i checked it can save 1800W of power…The devices that i have connected on it consume approximately 1100W and my question is how can i compute how long UPS it will run?
Most UPS vendors have programs either on their site or in the program of the UPS to determine and calculate the run time. I found this that may help:
The key is to use the watts you know to calculate the amps at the battery voltage . For example, say you want to run a 250 watt 110VAC light bulb from an inverter for 5 hours. Amp-hours (at 12 volts) = watt-hours / 12 volts = 1470 / 12 = 122.5 amp-hours.Nov 17, 2017
But check the vendors site first,
