Choosing a UPS for critical power usually starts with two questions: how much equipment do you need to keep running, and where can that equipment physically live? These two no-battery options - the Tripp Lite SMART1500LCDT and the APC SRT3000RMXLA - sit at opposite ends of that decision. The Tripp Lite is the lower-priced unit, while the APC offers much higher capacity. Because neither unit includes batteries, the real choice is about capacity, form factor, and condition.
Quick verdict
If your setup is a desktop, a few network devices, or a small office stack, the Tripp Lite SMART1500LCDT is the more practical buy at USD 175.00. If your equipment needs 2700W of headroom, the APC SRT3000RMXLA at USD 203.62 is the capacity leader. The $28.62 gap separates a 900W unit from a 2700W unit, and that extra capacity comes with caveats.

- The APC wins for installations that need high wattage and can accept cosmetic wear and a couple of damaged components.
Product notes
Tripp Lite SMART1500LCDT 900W 1500VA Smart LCD UPS
The Tripp Lite is a black tower that can also be rack mounted. It includes surge protection and 10 outlets, so it can serve as the central protection point for a desktop workstation or a small network stack. Its lower price makes it the easier entry into no-battery UPS ownership. Its limitation is capacity: it suits lighter loads rather than dense racks. And because the unit is supplied without batteries, the backup function is not ready to use until you add them. If your critical power needs are modest, this is the simpler fit.
APC SRT3000RMXLA Smart-UPS SRT 3000VA Rackmount UPS
The APC is a 2U rackmount UPS with far more capacity than the Tripp Lite, making it the stronger choice for server racks and network gear that needs real headroom. It provides that capacity in a form factor built for a rack. The pre-owned condition includes visible cosmetic wear, damaged front bezel retaining clips, and a defective rear USB port. Those issues do not reduce the high wattage rating, but they do mean the unit is not cosmetically or functionally perfect. If your critical power setup is rack-based and your equipment demands that kind of power, this is the option that gives you the headroom.
Final choice by use case
- Choose the Tripp Lite SMART1500LCDT for desktop, small-office, or modest network loads when you want the lower-cost option.
- Choose the APC SRT3000RMXLA for equipment that needs high wattage and you can work with its caveats.
