Our Take

Best for: Best for home office workers needing basic backup for a computer and router.

The Vertiv Liebert PST5-660MT120 is a straightforward standby UPS designed for home offices or small electronics. It offers 660VA/400W of backup power across 8 outlets, with 4 providing battery support and surge protection, and the other 4 handling surge-only. The LCD screen is a nice touch, letting you see load level and battery status at a glance. It also includes RJ45 and coax surge protection, which is useful for network gear. What stands out is the price for a brand like Vertiv, which is known for commercial-grade power equipment. The 400W limit means you won't run a gaming PC or large server, but it handles a desktop computer, monitor, and router fine. The included USB port for charging phones is handy, though it's standard 5V. The free shutdown software works with Windows and macOS, giving you time to save work. A limitation is the relatively low wattage compared to similarly priced units from APC or CyberPower. Also, the battery runtime is modest - expect about 5-10 minutes under half load. 40, this is a solid buy for basic protection, especially if you trust Vertiv's reliability over consumer brands.

Price Analysis

The current price of $83.40 is 27% off the $114.79 list price and well below the 30-day average of $114.79. It's also lower than the 90-day average of $107.24 and the 180-day average of $98.73. This is near the lowest price seen recently, making it a good time to buy.

Common Questions

How long will this UPS run my computer during a power outage?

At half load (200W), you can expect around 10-15 minutes of runtime, enough to save work and shut down. At full 400W load, runtime drops to about 5 minutes.

Does this UPS work with a gaming PC?

It can support a low-power gaming PC if the total draw stays under 400W, but most gaming systems with a dedicated GPU exceed that. It's better suited for office PCs or home theater gear.

Can I replace the battery in this UPS?

Yes, the battery is user-replaceable. Vertiv sells replacement battery packs, and the 3-year warranty covers the battery for the first year.
