APC by Schneider Electric SMT750R2X122 vs CyberPower PR750LCDRT1U: Specification Comparison
Both the APC SMT750R2X122 and CyberPower PR750LCDRT1U are 750VA rack-mount UPS systems designed for IT closets, edge deployments, and small server rooms running 120V infrastructure. They occupy the same VA class and target the same buyer profile — installers and IT managers needing runtime backup for network gear, cameras, or edge compute. The comparison turns on form factor (2U vs 1U), output waveform, input protection range, runtime, warranty, and the practical tradeoffs that follow from each manufacturer's design choices at this capacity tier.

Which UPS delivers more usable runtime and battery capacity at 750VA?
The APC SMT750R2X122 is rated at 750VA / 500W and specifies 5 minutes of runtime at full load and 16 minutes at half load (250W). Battery chemistry is lead acid; recharge time is listed as 3 hours. No battery cell count or individual cell voltage is provided in the APC spec sheet supplied.
The CyberPower PR750LCDRT1U shares the 750VA rating but its watt rating is not stated in the provided specifications. Its battery is specified as 4 × 6V/7Ah sealed lead-acid cells, giving a total string of 24V at 7Ah (168Wh nominal). Runtime figures at full or half load are absent from the provided CyberPower specs.
Buyers comparing runtime must note that APC provides explicit minute-based runtime figures (5 min full / 16 min half) while CyberPower's provided specs omit runtime entirely. APC's battery chemistry is noted generically as 'lead acid' with no cell-level detail; CyberPower specifies 4 × 6V/7Ah cells but does not translate that to a runtime number here. Neither set of specs states power factor, which affects the VA-to-watt conversion and true usable capacity.
How do physical footprint, mounting options, and outlet configuration differ between the two units?
The APC SMT750R2X122 occupies 2U of rack space (3.3" H × 17" W × 26.3" D) and is specified as rack-mount only. It provides 6 NEMA 5-15P receptacles on the output side and accepts input via a NEMA L5-15P plug — a twist-lock connector that requires a matching receptacle or adapter at the power distribution point. Circuit protection is via circuit breaker. Weight is not provided in the supplied specs.
The CyberPower PR750LCDRT1U is a 1U unit (1.75" H × 17.25" W × 15.8" D), saving one rack unit versus the APC. It supports both rack and tower mounting. Output receptacle count and type are described in the model name as '7 OUT 5-15R' (seven NEMA 5-15R outlets), and input is via a standard 15A connection. Weight is 30.7 lb. Circuit protection type is not specified in the provided data.
The CyberPower unit is physically shallower by 10.5 inches (15.8" vs 26.3") and saves 1U, which can matter in shallow-depth or fully-populated racks. The APC's twist-lock L5-15P input plug requires a compatible source circuit; the CyberPower's standard 5-15 input is more universally compatible with existing 15A circuits without adapters. CyberPower provides one additional outlet (7 vs 6).
Which unit offers better output power quality, input tolerance, and environmental or compliance assurances?
The CyberPower PR750LCDRT1U is specified as a Pure Sinewave output UPS (per the product name and 'Smart App Sinewave' sub-brand designation) with output voltage of 120 VAC ± 5%. Its input accepts 80–150 VAC nominal, a 70V tolerance window. Operating temperature is stated as 32–104°F (0–40°C). The unit carries UL1778 listing and RoHS compliance. Warranty is 3 years limited.
The APC SMT750R2X122 specifications provided do not state output waveform type (sine, simulated sine, or stepped approximation). Output voltage is listed as 120V with no stated tolerance. Input voltage is listed as 120V with no stated range tolerance. No operating temperature, compliance certifications, or warranty term appear in the provided APC spec data.
For loads sensitive to waveform quality — active PFC power supplies in servers, variable-speed drives, or medical-grade equipment — output waveform is a critical buying criterion. CyberPower explicitly specifies pure sinewave output; APC's provided specs are silent on this point. Similarly, CyberPower's stated input range (80–150V) gives buyers a concrete tolerance figure for line sag/surge conditions; APC's provided specs do not include this figure. Neither spec sheet specifies transfer time to battery.
Which should you choose: the SMT750R2X122 or the PR750LCDRT1U?
Our take: The CyberPower PR750LCDRT1U is the stronger choice when rack space, waveform quality, input voltage tolerance, and warranty assurance are the primary decision criteria. It saves 1U of rack space (1U vs 2U), is 10.5 inches shallower (15.8" vs 26.3" depth), explicitly delivers pure sinewave output at 120 VAC ±5%, accepts a wide 80–150 VAC input range, carries UL1778 and RoHS certifications, provides one additional outlet (7 vs 6), and includes a documented 3-year limited warranty — none of which appear in the APC provided specs. The APC SMT750R2X122 is the stronger choice when explicit runtime figures are required for site documentation: it states 5 minutes at full load and 16 minutes at half load, data CyberPower's provided specs do not include. The APC's NEMA L5-15P twist-lock input suits facilities already wired for L5-15 circuits but adds an adapter requirement elsewhere. Buyers prioritizing server or active-PFC load compatibility should favor the CyberPower's confirmed pure sinewave output.

Frequently Asked Questions
Which should you choose: the SMT750R2X122 or the PR750LCDRT1U?
The CyberPower PR750LCDRT1U is the stronger choice when rack space, waveform quality, input voltage tolerance, and warranty assurance are the primary decision criteria. It saves 1U of rack space (1U vs 2U), is 10.5 inches shallower (15.8" vs 26.3" depth), explicitly delivers pure sinewave output at 120 VAC ±5%, accepts a wide 80–150 VAC input range, carries UL1778 and RoHS certifications, provides one additional outlet (7 vs 6), and includes a documented 3-year limited warranty — none of which appear in the APC provided specs. The APC SMT750R2X122 is the stronger choice when explicit runtime figures are required for site documentation: it states 5 minutes at full load and 16 minutes at half load, data CyberPower's provided specs do not include. The APC's NEMA L5-15P twist-lock input suits facilities already wired for L5-15 circuits but adds an adapter requirement elsewhere. Buyers prioritizing server or active-PFC load compatibility should favor the CyberPower's confirmed pure sinewave output.
Does the CyberPower PR750LCDRT1U output pure sinewave power, and does the APC SMT750R2X122?
The CyberPower PR750LCDRT1U is explicitly specified as a pure sinewave output UPS (sub-brand 'Smart App Sinewave'). The provided APC SMT750R2X122 specifications do not state the output waveform type, so no comparison can be made from the supplied data on that point.
Which unit fits in a shallower rack cabinet — the SMT750R2X122 or the PR750LCDRT1U?
The CyberPower PR750LCDRT1U is significantly shallower at 15.8 inches deep versus the APC SMT750R2X122 at 26.3 inches deep — a difference of 10.5 inches. The CyberPower also occupies only 1U of rack height compared to the APC's 2U, making it a better fit for space-constrained or shallow-depth enclosures.
What is the backup runtime for each unit, and which provides more documented runtime data?
The APC SMT750R2X122 provides explicit runtime figures: 5 minutes at full load (500W) and 16 minutes at half load (250W), with a 3-hour recharge time. The CyberPower PR750LCDRT1U's provided specifications do not include runtime figures at any load level, though the battery is specified as 4 × 6V/7Ah sealed lead-acid cells. For site documentation requiring stated runtimes, the APC spec sheet supplies that data; CyberPower's does not.
