CyberPower CP500PFCRM1U PFC Sinewave UPS Battery Backup and Surge Protector, 500VA/300W, 6 Outlets, AVR, 1U Rackmount, UL Certified
Quick take
The CyberPower CP500PFCRM1U is a compact 1U rackmount UPS designed to protect equipment that benefits from a sine-wave output and PFC compatibility. It includes AVR for minor voltage correction and a multifunction LCD for status and alerts, plus surge protection across its outlet set. The main buying caveat is capacity, it is rated for 300W maximum and its listed runtime is about 2 minutes, so it is best for short, controlled shutdowns or protecting smaller loads.
Pros and cons
Pros
- PFC sinewave battery backup, useful for power supplies that need sine output compatibility.
- 6 outlets with a clear split (4 battery backup and surge protected, 2 surge protected only).
- AVR helps correct minor power fluctuations without immediately using battery power.
- Multifunction LCD shows runtime in minutes, battery status, and power conditions.
Cons
- Limited backup time (listed runtime is 2 minutes), which may not be enough for long workflows.
- Remote management requires an optional management card (not included), so monitoring setup may cost extra.
- Capacity is modest (300W / 500VA), so higher-draw equipment may exceed its rating.
What buyers think
Buyer review evidence is limited, but the feedback clusters around two themes. Many buyers report the UPS is solid and performs as intended for ongoing protection, including setups where it has been running for months without noticeable issues. There are also mentions of straightforward installation and software/monitoring compatibility, specifically via Network UPS Tools integration.
Key features that matter for real-world setups
1U rackmount format for tight spaces
With a depth listed at 9.04 inches and a 1U form factor, this UPS is built for shorter racks where space is at a premium. The metal enclosure and 18 lb weight suggest it is meant for semi-permanent rack installation rather than portable use.
PFC sinewave output for compatible power supplies
This model is designed around sinewave output for battery backup, targeting equipment with active PFC power supplies. If your rack gear includes modern power supplies that are sensitive to waveform type, choosing a sinewave UPS like this one can help reduce compatibility headaches compared with units that only provide stepped approximations.
Outlet layout: battery backup where you need it
It provides 6 NEMA 5-15R outlets, split into 4 battery backup and surge protected outlets, plus 2 surge protected outlets. That split is handy if you want to keep critical devices alive during outages (networking gear, a NAS, security systems) while routing less-critical peripherals through surge-only protection.
AVR and EMI/RFI filtration for day-to-day stability
Automatic Voltage Regulation (AVR) corrects minor power fluctuations without switching to battery power, which can improve battery longevity in environments with frequent small voltage swings. The UPS also lists EMI/RFI filtration, which can be a useful quality-of-life feature for sensitive A/V or networking equipment.
LCD status and alerts
The multifunction LCD panel is meant to make it easy to confirm runtime in minutes, battery status, and power conditions. That helps with quick decisions during an outage, like knowing whether you have enough time for a controlled shutdown.
Performance and limits (capacity and runtime)
The CP500PFCRM1U is rated at 500VA / 300W (120V input/output). It lists a runtime of about 2 minutes, which strongly suggests it is intended for short protection windows, such as powering networking equipment long enough to notify systems and shut down safely.
Before buying, check the total expected load of your critical devices. If you have equipment that draws near or above 300W when running, you can run into reduced protection time or exceeding the UPS rating.
Remote monitoring and software integration
Remote management is supported, but it requires an optional Remote Network Management Card. That matters if you want network-based monitoring or alerts without being physically at the rack. Some buyers also reference working with Network UPS Tools, which can be relevant if you are planning to integrate UPS status into a home lab or monitoring stack.
Pros and cons summary
Who this UPS is best for
- Small rack setups that need a 1U UPS with PFC-compatible sinewave backup.
- Network and security equipment where battery runtime of a couple minutes is acceptable for orderly shutdowns.
- Buyers who want AVR and clear outlet separation (battery-backed vs surge-only).
Who should look elsewhere
- Anyone needing long runtime during outages, because the listed runtime is short.
- Shoppers powering higher-draw equipment that may exceed 300W capacity.
- Buyers who need turnkey remote monitoring out of the box (an optional management card is required).
Price and availability
Check current pricing and ordering options before purchasing, since UPS pricing can fluctuate based on supply and demand.
FAQ
Is the CyberPower CP500PFCRM1U a sine wave UPS?
Yes. It is designed to provide sinewave output for battery backup, which is typically important for compatibility with active PFC power supplies.
How many outlets does it have, and how are they split?
It has 6 NEMA 5-15R outlets: 4 battery backup and surge protected outlets, plus 2 outlets that are surge protected.
Does it include AVR (automatic voltage regulation)?
Yes. It includes Automatic Voltage Regulation (AVR) to correct minor voltage fluctuations without switching to battery power.
What runtime should I expect?
The listed runtime is about 2 minutes. Actual runtime can vary based on your connected load.
Can I monitor it remotely?
Remote management is available, but it requires an optional management card (such as a Remote Network Management Card).
What’s the power capacity, and will it handle my gear?
It is rated for 500VA / 300W maximum output capacity. You should total the wattage of your devices during normal operation and keep it within the UPS rating to avoid exceeding its limits.
Final verdict
The CyberPower CP500PFCRM1U is a strong fit for compact rack environments that prioritize sinewave, PFC-friendly battery backup, and surge protection, with AVR smoothing minor issues before the battery is used. It is best for smaller, critical loads where a short runtime is enough to complete a controlled shutdown. If you need longer backup time or higher watt capacity, you will likely want to step up to a larger UPS model.
