Community Reviews

This APC Smart-UPS is a short-depth lithium ion rackmount UPS aimed at clean power, voltage regulation, and graceful shutdown for servers or NAS gear. The strongest praise centers on true UPS behavior, USB communication with Synology, email alerts, and proper shutdown signaling, with the lithium battery seen as a modern step up from older SLA units. Runtime is still only a few minutes, so it is mainly for bridging outages rather than long backup. Shipping availability is the big caveat, since the listing repeatedly shows ineligible or unconfirmed delivery to many states.

  • Rackmount server owners needing clean shutdowns, because it provides voltage regulation, USB communication, and remote management for Synology and networking gear.

  • IT setups that need true UPS behavior, because portable power stations lack voltage regulation and graceful shutdown support.

  • Users wanting a lithium UPS with longer service life than SLA batteries, because LiFePO4 is described as lasting far longer than lead-acid packs.

  • Short-depth rack builders, because the chassis is aimed at AVR racks and fits where deeper units are awkward.

  • Shoppers in states with strict shipping restrictions, because the listing can reject addresses in multiple states.

  • Budget buyers comparing watt-hours, because the runtime is short and the cost per stored energy is far higher than a portable power station.

  • Home backup buyers needing long outage runtime, because it only provides minutes before draining.

  • People expecting a portable power station replacement, because it is a true UPS with regulation and shutdown features rather than extended-energy storage.

This, Eaton 5px, or Anker C2000?
That all depends on your needs. See my post above regarding the differences in technologies. Your choices are only down to two since this unit appears to be vaporware as no one has been able to purchase the unit for shipping.

Do not confuse EcoFlow/Bluetti/Anker/or any other portable power station with a true UPS like APC/Vertiv/CyberPower. They all provide power during a power outage, but the similarities end there.None of the portable power stations provide any type of voltage regulation. So no voltage spike/sag protection.Only one Ecoflow unit and GoldenMate offers any type of 2 way communication to support graceful shutdowns and monitoring. The EcoFlow has very limited UPS support. They have not added any new support in over a year. The GoldenMate sends false power outage alerts every few minutes. Their solution is to just disable monitoring and 2 way communication.If all you want is to power devices in the event of a power outage, a portable power station is definitely the better option. If you want/need either of the two things I mentioned, stick to a real UPS.Another option which I use, is a hybrid system. I run both. My devices connect to the UPS to provide clean power and graceful shutdown.The UPS is then connected to a portable power station for extended runtimes. The caveat is that UPSes (I've tested APC/CyberPower and Vertiv) will have a ground fault alarm when used with Anker (C100, C1000, C1000 Gen2, C2000, Powerhouse 767) and EcoFlow (Delta 3 Plus) due to how they implement their internal grounding system. This issue is not present in any of my Bluetti units (AC180, Elite 100v2, Elite 200v2, Elite 300v2, AC300, AC500).
I have a goldenmate with communication and it has never once sent a false power outage that I am aware of. It shows up on my Unraid dashboard as connected.

Maybe just an issue with Synology. Both of my GoldenMates had the same issue with both of my Synology units.I searched online and others have reported the same issue. My email was getting flooded with power outage alerts every few minutes. GoldenMate also acknowledged that they were aware and the only fix was to disable monitoring. That still doesn't fix the other major issue that there is no voltage regulation on the GoldenMate units.

Yea this is pretty much vaporware. There have been numerous report of the same issue and not one person has confirmed being able to order one. I get the same shipping error message for multiple areas of Texas, Nevada, New Jersey, Arizona, Georgia, NoCal and SoCal.

Grossly overpriced for what it is. Consider Goldenmate for cheaper options.

You get what you pay for. GoldenMate is not really a true UPS. Other than it does provide power when you have a power outage, it does not provide any of the other benefits of a real UPS. I bought two and returned them both.

Better to just buy a portable power station from Anker, Bluetti, EcoFlow, etc if you are considering the GoldenMate. They are cheaper/kWh, support higher powered devices and offer better features and support.

What specifically does it not do?

I've been using one for about three months for a Synology NAS, NVR, and other networking gear. It works well and talks to the Synology over USB, including generating emails when it comes off of line power and providing a proper shutdown signal.

Which Synology do you have? I have a DS2415+ and DS1817+. The GoldenMate send false positives every few minutes to both my Synology units. I'm not the only person having this issue either. At the time, GoldenMate support acknowledged the issue and told me the only "fix" was to disable monitoring in my Synology.

The GoldenMate also do not provide any type of voltage regulation. My area suffers from frequent voltage spikes >135V and sags <105V numerous times weekly. My APC, CyberPower and Vertiv units will keep the output stable whereas the GoldenMates will not.

Maybe they've released an updated unit that works with older Synology units. Mine (GoldenMates) were purchased about 11 months ago.

Just look at the spec sheets, it's obvious GoldenMate isn't even in the same class.

I don't see any efficiency spec on their most expensive unit. No surge specs either. Warranty is less than half of the APC unit. No network management either (APC software exposes a massive amount of info). We know APC makes good UPS units, hard to say about a company that doesn't even publish a physical adrress.

Taking a step back, there's a lot to UPS systems that matter not on the marketing material like self testing, battery balancing, and if the company will still be supporting to the product in 5 years.

This unit at $648 (free shipping) is cheaper than refurbished lead acid APC units of similar size.

(ignoring that it doesn't actually ship anywhere)

I have the DS224+, and the Goldenmate works with its built-in UPS management features that you can get to in the Synology Control Panel. Generates emails, provides time estimates of battery life remaining, etc.

I haven't had any false alarms. Any time it's kicked on, my CyberPower UPS nearby also kicks on.

When the SLA battery in my CyberPower dies, I'll probably swap it out for the GoldenMate as well.

I don't have anything against APC, they're just expensive for using what is now quite outdated technology in the SLA batteries. There's no reason for them not to move over to Lifepo4, and there shouldn't be a significant cost increase in doing so. SLAs only last a couple years, while Lifepo4 will have around 75-80% life left at 10 years. They have double the depth of discharge and the BMS manages balancing cells. They've taken over the marine, RV, and solar industries, and there's no reason why UPSs should be so far behind.

I guess they work with the newer Synology units. Mine are quite old and will be retired soon. The DS2415+ is now a cold, offsite backup. The DS1817+ will soon follow. I'm pretty much done with Synology and any other proprietary products. I just wish the hardware wasn't locked down preventing me from installing TrueNAS on them.

I couldn't agree more. The companies producing true UPS systems are absolutely raping us with the cost of their LiFePO4 systems. That's why I run a hybrid setup using the UPS for the three important features of the voltage regulation, communications and remote management. Then they get plugged into a portable power station for extended runtimes.

Until the price of LiFEPO4 UPS systems come down, I'll be replacing the SLA batteries in my UPS and running this setup. I may still run the dual setup for the extended runtimes though.
