When you're shopping for UPS critical power, the decision usually comes down to capacity versus footprint. Do you need a compact unit that mounts in a rack, or a larger freestanding unit that can keep computers and networking gear alive through a longer outage? These two Tripp Lite UPS systems take opposite approaches.
Quick verdict
If you need a new, ready-to-install UPS for a modest load, the SMART500RT1U is the simpler choice. If you need more headroom, want an LCD status display, and are willing to work around a unit that ships without batteries, the SMART1500LCDT handles bigger loads.

Product notes
Tripp Lite SMART1500LCDT
This 1500VA/900W tower UPS is the higher-capacity option here, and the 10 outlets give you plenty of room for computers and networking equipment. The Smart LCD display makes it easy to monitor load and battery status. Surge protection is built in. The catch: it ships without batteries, so you have to source replacement batteries before it can actually provide backup power. It's also a used unit, so inspect it carefully before putting it in front of critical equipment. If you need big capacity and don't mind the extra setup, this is a strong contender.
Tripp Lite SMART500RT1U
This 1U UPS is brand new and factory sealed, so it's the more turnkey option. The 500VA/300W rating is enough for networking gear or a small workstation. It has six outlets, including a surge-only outlet for peripherals you don't want on battery. The AVR feature keeps output at 120V during brownouts as low as 90V without draining the battery. The tradeoff is capacity: 300W won't support larger servers or high-power desktops, and with only 500VA of runtime behind it, you'll want to keep the load modest if you need extended holdover. For a compact office setup, this unit is ready to go.
Final choice by use case
Go with the SMART500RT1U if you need a ready-to-run UPS for a modest load. Choose the SMART1500LCDT if you need to support heavier loads and can manage a little setup.
