UPS Backup for R710's (750w and 550w)?

Question

Trying to determine what type of UPS to buy that will have enough wattage to handle my R710's.

Servers:

R710 750w x 2
R710 550w x 2

My plan is to buy two of these:
CyberPower CP1500AVRLCD Intelligent LCD UPS System, 1500VA/900W, 12 Outlets, AVR, Mini-Tower

For the 750w rig, connect one power supply to the first battery backup outlet and one to a non battery backup outlet on the first UPS
For the 550w rig, connect one power supply to the second battery backup outlet and one to a non battery backup outlet on the second UPS

Does that sound like an acceptable solution or is that not wise? I don't need both power supply's on backup but I would like to have one and just have them gracefully shutdown if we have an outage that lasts 1 or 2 minutes.

That will be plenty, Id think.

An R710 will sit at around with no load 200w, 0.6amp/ so that will be around 20mins+/- runtime, are you adding switches and other hardware to the UPS as well?

The software will allow you to choose from max run time and power off at 5min power left,,or max power-saving and put the server into a low power state as soon as an outage is detected after a set time.

the one i have is the CyberPower VALUE2200EILCD Value Series (1320W/2200VA)

that runs my pc for a good 45mins on battery at 190w

Thanks for the post. I plan to have a UPS for each R710 and nothing else. I already have a UPS for my router, switch, and synology drives.

Is there an easy way to see how much power the R710 is using, in terms of watts? Perhaps it's in the iDRAC and I have just noticed it before. I'll also google to see if I can find some open source software to give me some power stats.

I found some power consumption stats in the iDRAC. For the rig with the 750w PSU's I found the following...

Max consumption: 356w
Avg consumption: 225w
Min consumption: 220w

I should be in good shape with the setup I had in mind. Thanks again! I will mark this as answered.
