Best UPS for Synology NAS
As a passionate enthusiast of digital archiving and home lab setups, I can tell you that a Synology NAS is an incredible piece of kit for safeguarding your precious data, streaming media, and running various services. But let’s be honest, even the most robust NAS is vulnerable to the fickle nature of your home or office power supply. That’s where an Uninterruptible Power Supply (UPS) steps in, not just as a backup battery, but as an essential guardian for your data integrity. Imagine losing hours of work or facing a corrupted RAID array because of a sudden flicker! A good UPS ensures your Synology NAS can gracefully shut down during an outage, preventing data loss, drive damage, and unnecessary downtime. It’s about peace of mind, knowing your digital life is protected.

These UPS have been specially selected for your Synology NAS and are optimally suited for UPS. Each description has been carefully created to provide you with informed and precise information.
CyberPower CP1500PFCLCD PFC Sinewave UPS System View on Amazon
If you’re serious about protecting your Synology NAS and other sensitive electronics, the CyberPower CP1500PFCLCD is, in my opinion, an absolute champion. This unit provides 1500VA/1000W of pure sine wave output, which is crucial for modern Active PFC (Power Factor Corrected) power supplies often found in NAS devices and computers. Simulated sine wave can sometimes cause stress or even damage to these sensitive components, so pure sine wave is a significant advantage. It boasts 12 outlets in total, with 6 offering battery backup and surge protection, and 6 additional surge-only outlets for less critical devices. The multi-function LCD panel provides real-time information on battery status, load, and runtime, which I find incredibly useful. Connectivity to your Synology NAS is via USB, allowing for automatic, graceful shutdowns through Synology’s DSM software. With its Automatic Voltage Regulation (AVR) feature, it also corrects minor power fluctuations without switching to battery, prolonging battery life. This unit offers excellent runtime for typical NAS and network gear, giving you ample time for safe shutdowns.
Pros

Buying Guide: What to Consider When Purchasing UPS for Synology NAS
Choosing the right UPS for your Synology NAS isn’t just about picking the biggest one you can find; it’s about smart planning to ensure your valuable data remains safe and accessible. Think of it as investing in an insurance policy for your digital life! The primary goal of a UPS with a Synology NAS is to provide enough bridge power for the NAS to perform a graceful shutdown in the event of a power outage, preventing data corruption and drive damage. You want a unit that seamlessly integrates with Synology’s DiskStation Manager (DSM) for automatic communication. Beyond that, consider the total power draw of your NAS and any other critical devices you want to keep running, even if just for a few minutes, like your router or modem.
When I advise friends on their NAS setups, I always emphasize that over-provisioning slightly is better than under-provisioning. Power events can be unpredictable, and a little extra headroom in your UPS can save you a lot of headaches. Always check the Synology compatibility list, but don’t be afraid to consider models that aren’t explicitly listed, as many compatible UPS units exist, provided they offer standard USB communication.
The Most Important Criteria at a Glance:
- VA/Wattage Rating: Calculate the total wattage of your Synology NAS plus any connected devices (router, modem, switch). Then, choose a UPS with a VA rating that is 50-70% higher than your total calculated wattage to allow for efficiency losses and future expansion.
- Pure Sine Wave Output: For modern, sensitive electronics like your Synology NAS, a pure sine wave output is highly recommended. It provides cleaner, more stable power than simulated sine wave, reducing stress on power supply units and ensuring optimal operation.
- USB Connectivity for DSM: This is non-negotiable! The UPS must have a USB data port that allows it to communicate with your Synology NAS, enabling DSM to monitor battery status and initiate an automatic, graceful shutdown during a power event.
- Runtime: While a few minutes are often enough for a graceful shutdown, aim for at least 5-10 minutes under full load. If you plan to keep network equipment online, consider a longer runtime.
- Automatic Voltage Regulation (AVR): Look for a UPS with AVR. This feature helps stabilize minor voltage fluctuations (sags and surges) in your utility power without switching to battery, thus preserving battery life and protecting your equipment from power inconsistencies.
FAQ: Frequently Asked Questions about UPS
Question 1: Why do I need a UPS for my Synology NAS?
A UPS is absolutely crucial for your Synology NAS because it acts as a critical buffer against power outages and fluctuations. Without one, a sudden loss of power can interrupt write operations to your drives, potentially leading to data corruption, file system errors, or even a full storage pool crash. The UPS provides a temporary power source, giving your NAS sufficient time to save all open files, unmount its volumes, and perform a safe, graceful shutdown. This prevents hardware damage and ensures that your data remains intact and accessible once power is restored. It’s truly an investment in the longevity and reliability of your NAS.
Question 2: What VA rating is suitable for my Synology NAS?
The suitable VA (Volt-Ampere) rating depends on the power consumption of your Synology NAS and any other devices you intend to plug into the UPS (like your modem, router, or network switch). A general rule of thumb is to choose a UPS with a VA rating 50-70% higher than the total wattage of all connected devices. For a typical 1-2 bay Synology NAS and a router, a 500-850VA UPS is often sufficient. For 4-8 bay models, or if you’re connecting more network gear, you’ll likely need something in the 1000-1500VA range. Larger 8-12 bay or rackmount NAS setups might even require 1500-3000VA. Always check your NAS’s power supply wattage and add a buffer!
Question 3: How do I connect a UPS to my Synology NAS and configure it?
Connecting a UPS to your Synology NAS is usually straightforward. Most compatible UPS units come with a USB cable that you connect from the UPS’s data port to any available USB port on your Synology NAS. Once physically connected, log into your Synology DiskStation Manager (DSM). Navigate to Control Panel > Hardware & Power > UPS tab. Here, you’ll enable UPS support. DSM should automatically detect the connected UPS. You can then configure settings such as the time before your NAS enters Safe Mode (e.g., 5 minutes after power loss) or whether it should wait until the UPS battery is low. Remember to also enable “Restart automatically after a power failure” in the General tab under Hardware & Power.
Question 4: Is a pure sine wave UPS really necessary for a Synology NAS?
While many modern power supplies in Synology NAS devices can technically operate on a simulated (stepped) sine wave UPS, a pure sine wave UPS is highly recommended, especially for critical data and sensitive electronics. Pure sine wave output mirrors the clean, smooth power waveform from your utility company, reducing electrical noise and heat buildup in your NAS’s power supply. This can extend the lifespan of your equipment and ensure optimal stability. Simulated sine wave UPS units are typically more affordable, but for peace of mind and the best possible protection for your investment, I always lean towards pure sine wave when budget allows.
Question 5: Can one UPS protect multiple Synology NAS devices?
Yes, absolutely! Synology DSM includes a fantastic feature called “Network UPS Server” that allows a single UPS connected to one Synology NAS (the “server” NAS) to relay power status information to other Synology NAS devices on your local network (the “client” NAS devices). To set this up, the primary NAS connects directly to the UPS via USB. Then, within the UPS settings on the primary NAS, you enable the Network UPS Server and input the IP addresses of your client NAS devices. The client NAS devices then configure their UPS settings to connect to the Synology UPS server, ensuring all connected NAS units perform graceful shutdowns in sync with the UPS.
