UPS recommendations

[cammelspit]

Howdy, I am looking at doing some upgrades for my server. I have two more 10TB drives coming in, a LSI controller card, a few other odds and ends. My UPS is too darn small... It lasts no longer than 3-4 minutes when the power goes out and recently it started losing capacity and needs to be replaced with something that can handle what I have. The UPS will have my server, one switch, and one modem on it. I am looking at this one.

You can see my specs in my sig. I would appreciate any other recommendations you guys can give me. I don't care for the 'cloud' BS this thing has but I am willing to just never use it. I am also curious if anyone has had any success using the plugins and such to get stats for this thing in unraid, is there a preferred brand for this stuff?

 

Thanks in advance!
