APC vs Vertiv UPS Comparison
Output Capacity
The APC BR1350MS offers significantly higher power capacity for your setup. It delivers 1350VA apparent power and 810W of real output wattage. This allows you to connect more devices or run higher-power equipment during an outage. In contrast, the Vertiv Liebert PowerUPS PUL-400LVT provides only 400VA apparent power. The data does not list a specific wattage output for the Vertiv unit. If you need to keep a full desktop computer, monitor, and peripherals running, the APC handles that load much better. The Vertiv is better suited for low-power networking gear or small electronics that require minimal backup power.
Waveform Quality
Clean power output is critical for sensitive electronics like computers and servers. The APC BR1350MS features a pure sine wave output. This waveform mimics utility electricity, ensuring your sensitive components run cooler and last longer. It also includes Auto Voltage Regulation to boost low or trim high voltage. The provided data for the Vertiv Liebert PowerUPS PUL-400LVT does not specify its output waveform. Without this specification, you cannot confirm if it delivers pure sine wave or modified sine wave power. For protecting expensive hardware from damage, the APC’s confirmed pure sine wave output is the safer choice for compatibility with complex power supplies.
Battery Chemistry
Battery type affects long-term maintenance and lifespan. The Vertiv Liebert PowerUPS PUL-400LVT uses Lithium-Ion battery chemistry. The data states this technology delivers up to three times the life expectancy of lead-acid batteries. This reduces the need for frequent replacements and maintenance over time. The APC BR1350MS uses a standard battery that is user-replaceable, with the model number APCRBC161 listed. While the APC battery is replaceable, the data does not specify if it is lead-acid or another chemistry, nor does it claim a longer lifespan than standard options. If you want a battery that lasts significantly longer, the Vertiv Lithium-Ion option has a clear advantage.
Physical Dimensions
Space constraints often dictate which UPS fits your workspace. The APC BR1350MS is a larger unit, measuring 14.5 inches in length, 10.2 inches in height, and 3.9 inches in width. It also weighs 25.7 pounds, indicating a substantial build for its higher capacity. The Vertiv Liebert PowerUPS PUL-400LVT is much more compact. It measures 8.27 inches in length, 5.51 inches in height, and 4.17 inches in width. It weighs only 3.9 pounds. If you have limited desk space or need to mount the unit in a tight area, the Vertiv’s small form factor is far more practical than the bulky APC tower.
Connectivity and Ports
How you connect devices matters for convenience. The APC BR1350MS provides ten total outlets, including six battery-backed outlets and four surge-only outlets. It also includes built-in coaxial and Ethernet surge protection. Additionally, it features built-in USB-C and USB-A ports for charging phones and tablets directly. The data for the Vertiv Liebert PowerUPS PUL-400LVT does not list the number of outlets, surge protection types, or charging ports. While the Vertiv may have these features, the APC explicitly offers extensive connectivity and charging options in its specification sheet, making it more versatile for a home office setup.
