APC by Schneider Electric SMX750I vs CyberPower PR750LCDRT1U: Specification Comparison
The APC Smart-UPS SMX750I and CyberPower PR750LCDRT1U are both 750VA line-interactive UPS systems in convertible rack/tower form factors, designed to protect sensitive equipment during power events. The SMX750I targets 230V international deployments, while the PR750LCDRT1U serves 120VAC North American installations. Despite this regional voltage difference, both units share the same device class, capacity tier, and pure sine wave output, making them a legitimate cross-shop for integrators sourcing across regions or evaluating competing UPS platforms for multi-site deployments.

How do power capacity, runtime, and waveform quality compare between these two 750VA UPS units?
Both units are rated at 750VA, and both deliver pure sine wave output — an important distinction for sensitive electronics and active PFC power supplies. The SMX750I specifies a 600W real-power rating, giving a power factor of 0.80. The PR750LCDRT1U does not publish a wattage rating in the provided specifications, so direct watt-for-watt comparison is not possible from available data.
The SMX750I provides explicit runtime figures: 12 minutes at full load (600W) and 34 minutes at half load (300W). The PR750LCDRT1U does not include runtime data in the provided specifications. Buyers sizing battery backup for a specific hold-over requirement should note that only the SMX750I's runtime is verifiable from supplied specs. The PR750LCDRT1U's battery is specified as 4 x 6V/7Ah sealed lead-acid; the SMX750I lists its battery as maintenance-free sealed lead-acid but does not itemize cell count or individual cell ratings in the provided data.
Which unit is more rack-efficient and easier to handle physically?
The CyberPower PR750LCDRT1U occupies 1U of rack space (17.25 x 1.75 x 15.8 in, W x H x D) and weighs 30.7 lb, making it a compact, low-profile choice for dense rack environments. The APC SMX750I is a 2U unit; only its height of 3.50 inches is specified in the provided data — full depth and width dimensions are absent — and it weighs 48.50 lb, roughly 58% heavier than the CyberPower unit.
For installations where rack unit economy is critical — high-density server rooms, co-location environments, or shallow-depth AV racks — the PR750LCDRT1U's 1U profile and lighter weight offer a meaningful physical advantage. The SMX750I's 2U footprint and 48.50 lb mass may be a constraint in weight-limited or space-constrained racks, though it also supports tower orientation. Both units are described as rack/tower convertible.
Are these units compatible with my regional power infrastructure, and what certifications and warranty protection do they carry?
This is the most critical differentiator: the APC SMX750I outputs 230V AC, conforming to European and international electrical standards, while the CyberPower PR750LCDRT1U outputs 120VAC ± 5% with an input range of 80–150VAC, designed exclusively for North American power infrastructure. These units cannot be substituted for each other in the same installation without a step-up or step-down transformer — they serve fundamentally different regional grids.
The PR750LCDRT1U carries UL1778 certification (the North American UPS safety standard) and is RoHS compliant, and comes with a 3-year limited warranty. The SMX750I's certifications and warranty terms are not listed in the provided specifications. Operating temperature for the PR750LCDRT1U is specified as 32–104°F (0–40°C); no operating temperature range is provided for the SMX750I in the available data. Buyers in regulated or insurance-sensitive environments should verify SMX750I certification marks independently.
Which should you choose: the SMX750I or the PR750LCDRT1U?
Our take: The SMX750I is the stronger choice when the deployment site runs on 230V infrastructure and longer, quantified runtime is a hard requirement. The SMX750I delivers a documented 12 minutes at full 600W load and 34 minutes at half load — runtime figures the PR750LCDRT1U does not publish — and its 600W real-power rating is explicit. The PR750LCDRT1U counters with a 1U rack profile versus the SMX750I's 2U, a weight advantage of 17.8 lb (30.7 vs 48.50 lb), a stated 3-year limited warranty, and UL1778 plus RoHS certifications that the SMX750I does not document in provided specs. For North American 120VAC rack environments where density and weight matter and runtime data will be sourced from CyberPower's published curves, the PR750LCDRT1U is the practical fit. For international 230V sites requiring verified hold-over time, the SMX750I is the documented choice.

Frequently Asked Questions
Which should you choose: the SMX750I or the PR750LCDRT1U?
The SMX750I is the stronger choice when the deployment site runs on 230V infrastructure and longer, quantified runtime is a hard requirement. The SMX750I delivers a documented 12 minutes at full 600W load and 34 minutes at half load — runtime figures the PR750LCDRT1U does not publish — and its 600W real-power rating is explicit. The PR750LCDRT1U counters with a 1U rack profile versus the SMX750I's 2U, a weight advantage of 17.8 lb (30.7 vs 48.50 lb), a stated 3-year limited warranty, and UL1778 plus RoHS certifications that the SMX750I does not document in provided specs. For North American 120VAC rack environments where density and weight matter and runtime data will be sourced from CyberPower's published curves, the PR750LCDRT1U is the practical fit. For international 230V sites requiring verified hold-over time, the SMX750I is the documented choice.
Can I use the APC SMX750I in a North American 120V facility?
No. The SMX750I is rated for 230V AC output and is designed for European and international power infrastructure. Connecting it directly to a North American 120VAC circuit without appropriate voltage conversion equipment would be unsafe and would void any applicable certifications.
Which UPS gives me more battery backup time?
Only the APC SMX750I provides runtime specifications in the available data: 12 minutes at full load (600W) and 34 minutes at half load. The CyberPower PR750LCDRT1U does not include runtime figures in the provided specifications — contact CyberPower or consult their published runtime curves for hold-over estimates at your actual load.
Does the CyberPower PR750LCDRT1U support pure sine wave output like the APC unit?
Yes. The CyberPower PR750LCDRT1U is branded under CyberPower's 'Smart App Sinewave' sub-brand, indicating pure sine wave output. The APC SMX750I also specifies sine wave output. Both units are suitable for equipment with active PFC power supplies that require or strongly prefer pure sine wave UPS protection.
