APC by Schneider Electric SMX750I vs CyberPower AVRG750U: Specification Comparison
Both the APC SMX750I and CyberPower AVRG750U are 750VA line-interactive UPS units sharing the same nominal VA rating and sealed lead-acid battery chemistry, making them legitimate cross-shop candidates. However, they target meaningfully different deployment contexts: the SMX750I is a 230V rack/tower convertible unit aimed at IT infrastructure and data center edge applications, while the AVRG750U is a compact 120V desktop unit designed for workstations and small office equipment. This comparison evaluates power architecture, runtime and form factor, and environmental and standards compliance.

How do the two units differ in output voltage, waveform, and rated watt capacity?
The SMX750I outputs 230V AC with a true sine wave, delivering 600W at its 750VA rating — a 0.80 power factor. The specs confirm its line-interactive topology under the Smart-UPS SMX series, which is associated with active voltage regulation. No input voltage range is specified in the provided data.
The AVRG750U outputs 120V AC ±5% from a 120V AC nominal input and is rated at 450W against its 750VA — a 0.60 power factor. Its waveform type is not stated in the provided specs. The lower watt rating at equivalent VA means the AVRG750U supports less real power load for the same apparent power rating compared to the SMX750I.
For buyers powering 230V IT equipment (servers, network gear in international or dual-voltage rack environments), only the SMX750I is applicable. The AVRG750U is strictly a 120V North American–market device.
Which unit provides more runtime, and how does physical form factor affect deployment options?
The SMX750I specifies 12 minutes of runtime at full load (750VA/600W) and 34 minutes at half load (375VA/300W). These are the only runtime figures provided; no battery Ah rating is disclosed in the available specs.
The AVRG750U provides a 12V/7Ah sealed lead-acid battery. No runtime figures in minutes are included in the provided specs, so a direct runtime comparison cannot be made from available data alone.
For form factor: the SMX750I is a 2U rack-mountable unit (also tower-convertible), weighing 48.50 lb — consistent with a rack chassis carrying a larger internal battery. The AVRG750U is a compact desktop unit measuring 12.2 x 7 x 3.5 in and weighing 13.44 lb, with keyhole mounting slots for wall or surface mounting. The SMX750I is the clear choice for rack environments; the AVRG750U suits workstation-side or shelf deployments.
What certifications, warranty terms, and operating conditions does each unit carry?
The AVRG750U carries explicit standards certifications: UL1778, Energy Star Certified, and RoHS Compliant. Its warranty is a 3-Year Limited with a $150,000 Connected Equipment Guarantee. Operating temperature is specified as 32–104°F (0–40°C).
The SMX750I provides no certifications, warranty terms, or operating temperature range in the provided specifications. Buyers requiring documented compliance (UL listing, Energy Star, RoHS) for procurement or facilities approval cannot confirm those from the available SMX750I spec sheet alone.
The AVRG750U's $150,000 Connected Equipment Guarantee is a notable buyer-protection differentiator that is absent from the SMX750I's listed specs. IT procurement teams with compliance or insurance requirements should note this gap in available SMX750I documentation.
Which should you choose: the SMX750I or the AVRG750U?
Our take: The SMX750I is the stronger choice when the deployment requires 230V output, rack integration, and documented sine-wave output for sensitive IT loads. It delivers 600W real power (versus 450W for the AVRG750U), specifies 12-minute full-load and 34-minute half-load runtimes, and fits standard 2U rack bays at a tower-convertible form factor. The AVRG750U, at 13.44 lb versus 48.50 lb, is purpose-built for compact 120V North American desktop deployments and brings documented UL1778, Energy Star, and RoHS certifications plus a $150,000 Connected Equipment Guarantee — none of which appear in the SMX750I's provided spec data. Buyers deploying 120V workstation or small-office environments in North America will find the AVRG750U appropriately sized and compliance-documented; those building 230V rack infrastructure should specify the SMX750I, subject to verifying certifications directly with APC.

Frequently Asked Questions
Which should you choose: the SMX750I or the AVRG750U?
The SMX750I is the stronger choice when the deployment requires 230V output, rack integration, and documented sine-wave output for sensitive IT loads. It delivers 600W real power (versus 450W for the AVRG750U), specifies 12-minute full-load and 34-minute half-load runtimes, and fits standard 2U rack bays at a tower-convertible form factor. The AVRG750U, at 13.44 lb versus 48.50 lb, is purpose-built for compact 120V North American desktop deployments and brings documented UL1778, Energy Star, and RoHS certifications plus a $150,000 Connected Equipment Guarantee — none of which appear in the SMX750I's provided spec data. Buyers deploying 120V workstation or small-office environments in North America will find the AVRG750U appropriately sized and compliance-documented; those building 230V rack infrastructure should specify the SMX750I, subject to verifying certifications directly with APC.
Can I use the AVRG750U to power my rack-mounted server equipment?
No — the AVRG750U outputs 120V AC and uses keyhole-slot compact mounting, not standard rack rails. It is not designed for rack deployment. The SMX750I is the rack-mountable option here, fitting a 2U slot and outputting 230V AC.
Which UPS gives me more runtime for a half-load scenario?
Only the SMX750I provides runtime figures in the available specs: 34 minutes at half load and 12 minutes at full load. The AVRG750U's spec sheet lists a 12V/7Ah battery but does not state runtime in minutes, so a direct comparison cannot be made from the provided data.
Is the AVRG750U or SMX750I better covered under warranty and compliance standards?
Based on the provided specifications, the AVRG750U is better documented for compliance: it lists UL1778, Energy Star, and RoHS certifications and includes a 3-Year Limited warranty with a $150,000 Connected Equipment Guarantee. No warranty terms, certifications, or operating temperature range are listed in the SMX750I's provided specs.
