UPS needs for small scale server room

[Anonymous user]

Hi there, I need a new UPS for a small scale server room, I was hoping some of you might be able to help narrow down my needs. Basically put I have the following I would like to run off the UPS: NAS(150W), Firewall(100W), DSL Model (18W), Switch (160-384W), I will also be adding a server shortly(500-750W) so about 1152 - 1402 Watts total, it has to be rack moutable, and all my devices use Nema 5-15P, I do not plan any more upgrades in the near future. Hopefully I did the formulas right!

Anyways I have it narrowed down to the following:

SMX1500RM2U, this will meet the lower end wattage requirements, but not the higher ones, so my server choice would be limited, but this one is also listed as compatible to my QNAP TS-439U-SP NAS, but I assume this only makes a difference if I was using the NAS for UPS management? Also most cost effective choice.

SUM1500RMXL2U, this will meet both needs for wattage, and also has a RJ45 jack for network management which seems to be a plus, also seems to have more "bells and whistles" but slightly more money that the SUA2200RM2U which has more power

SUA2200RM2U, this will meet all my needs, but seems to be an older model? Are the Nema 5-20P out plugs compatible with the 5-15P input? it seems they are 5-15/5-20

Anyways based on what I am looking to do, do any of these stand out to you as the choice for my setup?

thanks for your response, helps clear up a few things! So from looking at this I believe the SUA2200RM2U is the unit for me, even if its a bit older, from my calculations I should be able to have everything in the wiring closet run off the one UPS which is nice, and also leaves me some room for future considerations. In the end this is more important to me than network connectivity, which from my understanding I can also add a card into this unit if I wanted to go that way down the road.

Will this connect to my NAS through USB I wonder? or will it have to be configured off a termporary workstation, or a really long USB cord I plug into the closet until I get the server?

Thanks again!

Yes, you can definitely add a network card down the line if you wanted to.

I think your NAS might have native support for use with a UPS, though I'd double check on yours to be sure. If so, it could probably communicate over USB like you said.
