Hey There,
Thank you o much for the great work you do! I need advice regarding a UPS for our Sinology 1821+ with 6 drives currently installed. This unit will power only the NAS and a 10GB switch. Our editing station which use MacBooks or on separate UPS units.
Realistically looking to keep the Nasty running for 30 minutes - before shutting down.
Currently looking at the APC Performance BR1000Ms Sine Wave 1000VA -1500VA units or the MUCH more expensive SMC1500 units.
Three questions:
1) What Wattage of UPS do I need to use to power the NAS and switch for about minutes when the drives are in use?
2) I also have a fiber modem and Wifi Roueter in a separate location (120Watts max per together as or their power supply units) what UPS size would I need to keep things running for about 30 minutes there?
3) Is the cloud based Smart Connect worth the addition cost in the SMC1500 for my Synology Setup or will DSM view basic UPS status too? Thanks!

1) What Wattage of UPS do I need to use to power the NAS and switch for about 30 minutes when the drives are in use?
To determine the wattage, estimate the power consumption:
Synology DS1821+ (with 6 drives, in use): Approximately 59.8W
10Gb Switch: A reasonable estimate for a typical small to mid-sized switch could be around 50W.
Total Estimated Load: ~60W (NAS) + ~50W (Switch) = 110W.
It is recommended to add a buffer for potential peak loads or future expansion. A 20-25% buffer would bring the requirement to roughly 138-140W.
Therefore, for your NAS and switch, a UPS with at least 150-200W capacity would be ample. Both the APC BR1000MS (600W max) and BR1500MS (900W max) would easily cover this wattage requirement and provide well over 30 minutes of runtime for this load. The SMC1500 (900W max) would also be more than sufficient.
2) I also have a fiber modem and WiFi Router in a separate location (120 Watts max per together as or their power supply units) what UPS size would I need to keep things running for about 30 minutes there?
Estimate this load as well:
Fiber Modem: Typically 5-10W.
Wi-Fi Router: Typically 5-20W.
Total Estimated Load: ~10W (modem) + ~20W (router) = 30W.
For such a low power draw, a larger UPS is not needed. A smaller, dedicated UPS or even a mini-UPS designed specifically for modems and routers would work perfectly and could provide many hours of backup time. There are options available that cost significantly less than the larger UPS units you're considering for your NAS.
3) Is the cloud-based Smart Connect worth the additional cost in the SMC1500 for my Synology Setup or will DSM view basic UPS status too?
This is a great question, and the answer depends on your specific needs for monitoring and management:
Synology DSM and Basic UPS Status: Your Synology DSM (DiskStation Manager) can view basic UPS status when connected via USB. You can enable UPS support, set the time before the NAS enters Safe Mode, and configure shutdown actions within DSM. Most compatible UPS units will provide this level of integration. Always check the Synology UPS Compatibility List to ensure the specific model you choose is supported.
APC Smart Connect: This cloud-based feature offers more advanced monitoring and management capabilities. It provides real-time battery status updates, proactive notifications, and potentially more detailed performance analytics.
For your NAS and 10Gb switch: The APC BR1500MS (or even the BR1000MS) would be more than sufficient to provide over 30 minutes of backup time for your estimated ~110W load.
For your modem and router: A much smaller, dedicated UPS designed for network equipment would be ideal and very cost-effective.
Smart Connect: Evaluate if the advanced monitoring and remote management justify the higher price point for your specific business needs. The BR series will still allow your Synology NAS to perform safe shutdowns.
