APC by Schneider Electric SMT750R2X122 vs CyberPower AVRG750U: Specification Comparison
Both the APC SMT750R2X122 and CyberPower AVRG750U are 750VA/120V line-interactive UPS units aimed at protecting networked equipment, edge devices, and small server loads. The APC is a 2U rackmount unit with an L5-15P twist-lock input and six 5-15P receptacles, targeting rack-mounted infrastructure. The CyberPower is a compact desktop/tower unit with keyhole mounting slots, targeting workstations or distributed edge deployments. Same VA class, different physical formats — a legitimate cross-shop when buyers are evaluating total cost of protection at the 750VA tier across deployment styles.

Which UPS delivers more usable runtime and real watt capacity under load?
The APC SMT750R2X122 is rated at 750VA / 500W, yielding a 0.667 power factor. At full load (500W) it provides 5 minutes of runtime; at half load (250W) it extends to 16 minutes. Battery recharge time is specified at 3 hours. The APC uses a lead-acid battery chemistry but no specific Ah rating is provided in the supplied specs.
The CyberPower AVRG750U is rated at 750VA / 450W, yielding a 0.60 power factor. Runtime figures at any load level are not provided in the supplied specs. The battery is a sealed lead-acid 12V/7Ah cell. No recharge time figure is given in the supplied specs.
On raw watt capacity, the APC delivers 500W versus the CyberPower's 450W — a 50W or 11% advantage. The APC also provides explicit runtime benchmarks (5 min full, 16 min half load), whereas the CyberPower's runtime under load is unspecified in the provided data. Buyers requiring a minimum guaranteed runtime for graceful shutdown should note only the APC publishes this figure in the supplied specifications.
How do physical format, mounting, and input/output connectivity differ between the two units?
The APC SMT750R2X122 is a 2U rackmount chassis measuring 3.3" H × 17" W × 26.3" D. It requires rack space and a NEMA L5-15P twist-lock input circuit — a dedicated 15A locking receptacle not found on standard outlet strips. Output is six NEMA 5-15P receptacles. Circuit protection is via a built-in circuit breaker. Weight is not specified in the supplied data.
The CyberPower AVRG750U is a compact unit measuring 12.2" × 7" × 3.5" (310 × 178 × 89 mm) and weighing 13.44 lb (6.1 kg). It uses keyhole mounting slots, allowing wall or surface mounting without a rack. Input plug type and output receptacle count are not specified in the supplied data. Operating temperature is rated 32–104°F (0–40°C); no operating temperature range is provided for the APC in the supplied specs.
These units target different physical environments: the APC demands rack real estate and a twist-lock circuit, suiting telecom closets and server rooms. The CyberPower suits office desks, wall mounts, or shallow utility spaces. Installers must confirm the L5-15P input requirement for the APC before specifying it — a standard 5-15P wall outlet will not accept this plug without an adapter or dedicated circuit.
Which unit offers stronger compliance credentials and warranty coverage?
The APC SMT750R2X122 lists circuit breaker protection and the Smart-UPS series designation, but no UL listing, Energy Star status, RoHS compliance, warranty term, or connected equipment guarantee is stated in the supplied specifications.
The CyberPower AVRG750U carries UL1778 listing, Energy Star certification, and RoHS compliance as specified. Its warranty is 3 years limited, accompanied by a $150,000 Connected Equipment Guarantee — a specific financial backstop for downstream equipment damage. None of these credentials are documented in the APC's supplied spec sheet.
Based solely on the provided specifications, the CyberPower presents a more complete compliance and warranty picture: three named standards (UL1778, Energy Star, RoHS), a defined 3-year warranty, and a $150,000 connected equipment guarantee. The APC's compliance and warranty details are absent from the supplied data and cannot be inferred or assumed. Buyers requiring documented UL listing or a connected equipment guarantee should verify the APC's credentials through the manufacturer's official datasheet.
Which should you choose: the SMT750R2X122 or the AVRG750U?
Our take: The SMT750R2X122 is the stronger choice when the deployment is rack-mounted infrastructure requiring maximum watt capacity and published runtime figures. It delivers 500W versus the AVRG750U's 450W — a 50W advantage — and is the only unit of the two with documented runtime benchmarks: 5 minutes at full load and 16 minutes at half load, critical data for shutdown scripting. However, it requires a NEMA L5-15P dedicated circuit and 2U of rack space, limiting it to purpose-built rack environments. The AVRG750U fits desktop, wall-mount, or shallow-closet installations where rack space is unavailable, meets UL1778 and Energy Star standards as specified, and carries a documented 3-year warranty with a $150,000 connected equipment guarantee — none of which appear in the APC's supplied specs. Buyers in rack-dense security or IT closets should favor the APC; buyers deploying at the edge or in office environments without dedicated locking circuits should favor the CyberPower.

Frequently Asked Questions
Which should you choose: the SMT750R2X122 or the AVRG750U?
The SMT750R2X122 is the stronger choice when the deployment is rack-mounted infrastructure requiring maximum watt capacity and published runtime figures. It delivers 500W versus the AVRG750U's 450W — a 50W advantage — and is the only unit of the two with documented runtime benchmarks: 5 minutes at full load and 16 minutes at half load, critical data for shutdown scripting. However, it requires a NEMA L5-15P dedicated circuit and 2U of rack space, limiting it to purpose-built rack environments. The AVRG750U fits desktop, wall-mount, or shallow-closet installations where rack space is unavailable, meets UL1778 and Energy Star standards as specified, and carries a documented 3-year warranty with a $150,000 connected equipment guarantee — none of which appear in the APC's supplied specs. Buyers in rack-dense security or IT closets should favor the APC; buyers deploying at the edge or in office environments without dedicated locking circuits should favor the CyberPower.
Can I plug the APC SMT750R2X122 into a standard wall outlet?
No — based on the supplied specifications, the SMT750R2X122 requires a NEMA L5-15P twist-lock input. Standard wall outlets in North America are NEMA 5-15R and will not accept this plug. A dedicated locking-outlet circuit or appropriate adapter must be in place before installation. The CyberPower AVRG750U's input plug type is not specified in the provided data.
Does the CyberPower AVRG750U publish runtime figures like the APC does?
No runtime figures appear in the supplied CyberPower specifications. The APC SMT750R2X122 specifies 5 minutes at full load (500W) and 16 minutes at half load (250W). If a guaranteed minimum runtime for graceful server shutdown is a selection criterion, only the APC provides that data in the specifications supplied here — the CyberPower's runtime would need to be sourced from the manufacturer's full datasheet.
Which unit is better suited for a physical security headend rack with NVRs and PoE switches?
The APC SMT750R2X122 is the more natural fit for a headend rack: it occupies 2U of rack space, provides six output receptacles, delivers 500W of protected power, and offers a documented runtime curve. The CyberPower AVRG750U is a compact unit with keyhole mounting and 450W output — better suited to edge or desktop deployments rather than a populated rack. The prerequisite for the APC is a dedicated NEMA L5-15P input circuit at the rack PDU or wall feed.
