How many listings actually tell you the waveform

Of the 44 in-stock units we track, 28 state an output waveform - 64%. Of those, 28 say pure sine and 0 say simulated. The remaining 16 say nothing at all.

The asymmetry is the finding. Pure sine is a selling point and gets printed; a stepped approximation is not and does not. So a silent listing is more likely to be the cheaper waveform than the better one, and we still do not claim to know which - we count it as unknown and tell you to check the datasheet.

Why almost everything lands here

1000 to 1500VA is where the market is thickest and it is not an accident. It is the smallest size that comfortably carries the realistic homelab load - a NAS, the switch, a small server or a mini PC, and the router - with enough left over that drive spin-up at power-on does not trip it.

Across the units we hold in this band the maker-stated real power runs 100-1500 W. That spread is worth staring at, because every one of these units is sold under a four-digit VA number that suggests they are interchangeable. They are not: two units with identical VA ratings routinely state materially different watts, and watts is the number your equipment actually consumes.

It is also the band where the two form factors genuinely overlap. A tower unit here will carry the same load as a rackmount one at a lower price, and the rackmount premium is buying you the mounting, not the capacity. If the equipment sits on a shelf, take the tower and the discount.

The load figures are yours to supply. Every device publishes its own power consumption in its own specifications; we do not publish a table of what a four-bay NAS draws, because we have not sourced one per machine and a plausible-looking number is not a source.

This is the band where signalling starts to matter

At this size you are usually protecting more than one machine, and the question of how the machines that do not hold the USB cable find out about the outage becomes real.

The vendors all solve it the same way under different names. One machine takes the USB cable and relays the state over the network - Synology calls it Network UPS Server, QNAP calls it network UPS master and slave, TrueNAS calls it master and slave. All three sit on Network UPS Tools underneath, which is why mixed environments generally work even though nobody guarantees a specific pairing.

The alternative is SNMP, where the UPS carries a management card and every machine queries it directly. That is more common a band up, but it exists here and it removes the failure mode where the machine holding the cable is also the machine that went down. QNAP's documentation lists USB, SNMP and network slave as three first-class options, so none of this requires unsupported configuration.

Whichever route you take, the comms column in the table above is doing more work than the runtime claims. A large battery with no data connection is a delay, not a protection.

Getting the sizing right, with a worked example that is not ours

Synology publish the method and we use theirs rather than inventing one: total the real wattage of everything you intend to plug in, then divide by the UPS's output power factor, and the result is the output power the unit needs to be rated for.

Their worked example takes a 650 W load against a 70% output power factor and lands on 928.5 W. That number is instructive precisely because it is awkward: a unit sold as 1000VA but rated at 600 W does not carry that load, despite sitting in this band and carrying the reassuring four-digit label.

Their accompanying caveat is the one to remember when comparing two units in the table above: different manufacturers use different VA ratings based on the performance of their unit, so the watt figure has to come from the manufacturer's own manual rather than being inferred from VA. Where a listing states one, it is in the table; where it does not, the cell says so.

VA is not watts, and this is the sizing error people actually make

Sellers lead with VA because it is the bigger number. VA is apparent power; watts is real power, and watts is what decides whether your load fits. The ratio between them is the unit’s power factor and it is not a constant - Synology’s own guidance is that “Different manufacturers have different volt-ampere (VA) ratings based on the performance of their UPS. To determine the total power (W) that the UPS can support, we recommend consulting the manufacturer’s product manual.”

Their published method, which is the one these pages use rather than one of our own:

Output power required = total wattage of your devices / output power factor of the UPS

Synology’s worked example takes a 650 W load and a UPS with a 70% output power factor and arrives at 928.5 W - so a “1000VA” unit rated at 600 W would not have carried it, despite the reassuring four-digit number on the box. Add your own devices’ figures from their spec sheets; we publish no wattage on your behalf.

Where to go next

The UPS hub carries the waveform rule, the sizing method and the battery economics · 600-900VA · 1500VA and up · For a NAS · For a rack · tower vs rackmount (7 tower and 24 rackmount units sit in this band).

This page exists because the catalogue holds at least 4 units in the band. Bands below that floor are not published rather than published thin.

Frequently asked questions

Is 1500VA enough for a NAS and a small server?

Usually, but check it rather than assuming. Units in this band state 100-1500 W of real power. Total your devices' own wattage figures from their spec sheets, divide by the UPS's output power factor, and compare that against the watt rating in the table - not against the VA number on the box.

Tower or rackmount in this band?

Both exist here - 24 of the 44 units we track in this band are rackmount. If the equipment sits on a shelf, the tower is the same capacity for less money and the rackmount premium buys you mounting you do not need. If it goes in a rack, check the depth rather than the U count before ordering.

Why does this page show the waveform on every row?

Because it is the specification that decides whether the unit works with your hardware. An active power factor correction power supply - most servers, desktops and NAS units - can shut down unexpectedly when fed a stepped approximation of a sine wave, which CyberPower's own documentation names as the failure sine wave output exists to prevent. A listing that does not state its waveform is marked not stated rather than assumed safe.

Sources

Specification claims on this page were checked against the pages below on 4 August 2026. Where a widely-repeated figure did not survive that check, we report what the source says now and say so in the text rather than repeating the familiar number.

  1. CyberPower Systems - Active PFC Compatibility (glossary) (cyberpowersystems.com, 2026-08-20)
    Used for: the maker's own definition, quoted verbatim on our pages: Active PFC compatibility is "a feature of UPS systems that delivers sine wave output to prevent unexpected shutdowns or component stress for connected devices with Active PFC power supplies." This is the source for the spec-gate framing - the failure mode named by the maker is an unexpected shutdown, which is precisely the event a UPS was bought to prevent.
  2. Synology Inc. - How do I choose a suitable UPS? (Knowledge Center) (kb.synology.com, 2026-08-20)
    Used for: the sizing method used on these pages, quoted rather than paraphrased: "Output power = Total wattage of your devices / Output power factor of a UPS", with Synology's own worked example dividing a 650 W load by a 70% power factor to reach 928.5 W. Also the VA-versus-watts caveat in the vendor's own words: "Different manufacturers have different volt-ampere (VA) ratings based on the performance of their UPS. To determine the total power (W) that the UPS can support, we recommend consulting the manufacturer's product manual." Article last updated 1 April 2024.
  3. Synology Inc. - Products Compatibility List - UPS, filtered to tested by Synology (synology.com, 2026-08-20)
    Used for: the full tested list, captured in a rendered browser session: 79 entries, 73 UPS units and 6 management cards or protocol adapters. Also the vendor's own two operational notes, which we quote rather than restate: that any listed model can extend UPS service to a second Synology product over the network, and that "The UPS power-off function varies by brand and model. Please simulate a power outage to ensure the function performs as expected." The list is CATEGORY-level: it does not filter per machine.
  4. QNAP Systems - Configuring the UPS settings, QTS 5.2.x (docs.qnap.com, 2026-08-20)
    Used for: that QTS supports three connection modes - USB cable, SNMP over the network, and network UPS slave against another machine acting as the server - and the two configurable responses to a power failure: powering off after a set period, or entering auto-protection mode, which stops services and unmounts volumes.
  5. Network UPS Tools project - Network UPS Tools (NUT) - project overview and hardware compatibility list (networkupstools.org, 2026-08-20)
    Used for: the project's own description of its scope - "to provide support for Power Devices, such as Uninterruptible Power Supplies, Power Distribution Units, Automatic Transfer Switches, Power Supply Units and Solar Controllers" - its GPL licence, and the size of its hardware compatibility list at the date read: at least 199 manufacturers and 1,436 device models. We link this list; we do not reproduce it. It is maintained upstream, it changes, and a stale copy of somebody else's compatibility list is worse than a link to the live one.
  6. Schneider Electric (APC) - What is the expected life of my APC UPS VRLA battery? (se.com, 2026-08-20)
    Used for: the three-to-five-year expected service life of the sealed lead-acid battery in a typical APC UPS, and that operating temperature is the dominant factor in shortening it. The replacement-cartridge prices quoted on our pages are described as reported figures, not as our measurement - we do not track UPS battery prices.
  7. DatacenterDisk - Live catalogue - UPS listings (datacenterdisk.com, 2026-08-20)
    Used for: every price, VA rating, watt rating, outlet count and waveform statement on these pages, read from the seller's own title and feature bullets at seed time and refreshed by the price cron. The waveform coverage rate is recomputed on each render rather than frozen here.
