Tecmojo 1U Rack Mount 19 Outlet PDU
The Tecmojo PDU is a compact 1U rack-mount unit designed for space-saving 19-inch racks. It includes 16 rear-facing outlets plus three front-facing outlets, which helps maximize rear cable management while providing accessible front power access. A built-in 12-amp circuit breaker adds overload protection for connected equipment. Four USB ports support simultaneous charging or powering of peripheral devices, making it suitable for small servers, AV gear, and network closets.
Best for: small IT closets, home lab setups, and compact server rooms where space is at a premium and simple protection is required.
Caution: The USB ports are auxiliary; main power distribution relies on the 16 rear outlets and the 12A circuit breaker. Ensure your total load stays within the derived limits.
StarTech RKPW101920 10 Outlet Rack Mount PDU
This StarTech 1U PDU offers 10 outlets with a 16-amp rating in a horizontal 19″ rack format. It comes with an 8-foot NEMA 5-20P power cord and a front-facing power switch. The included cord is designed for 125V systems and is UL listed, which is beneficial for data centers and server rooms seeking compliant power distribution. Its 20-amp circuit breaker provides protection against overloads, and the VESA-style 1U horizontal mounting aligns with common rack standards.
Best for: mid-density rack deployments needing a straightforward, UL-listed horizontal PDU with clear outlet zoning.
Caution: The unit is most compatible with 125V environments; verify compatibility for your regional voltage before installation.
CyberPower PDU81007 Switched Metered-By-Outlet
The CyberPower PDU81007 is a metered-by-outlet, switched PDU designed for larger server rooms or data closets needing per-outlet visibility and control. It provides 16 front-mounted outlets with per-outlet metering, a digital display for amperage, voltage, and IP address, and both local and remote control of outlets. The derated 24A capability suits mid-to-high power deployments. Its switched design supports restarting devices and scheduling power operations to improve IT efficiency.
Best for: data centers or network rooms requiring proactive power management, remote control, and outlet-level visibility.
Caution: Per-outlet metering can reveal higher consumption; plan monitoring and alerting around peak usage to avoid unexpected overloads.
CyberPower PDU24004 Metered ATS PDU
The CyberPower PDU24004 combines metering with an automatic transfer switch (ATS) for redundancy. It offers 12 rear IEC-320 C13 outlets across 200-240V inputs, enabling dual power cords for alternate power sources. A color LCD panel shows key metrics, and the unit is compatible with sine wave power sources. This configuration is ideal for environments where reliable uptime and detailed power visibility are required, especially in IT closets with variable power sources.
Best for: setups that need redundant power feeds and per-outlet monitoring for critical equipment.
Caution: Ensure the two power cords can reach their respective power sources; misplacing cords can undermine redundancy benefits.
Pyle 19 Outlet 1U Rackmount PDU
The Pyle PDU865 is a 1U, 19-inch rack-mount power strip featuring 19 outlets (16 rear-facing + 3 front-facing) and four USB ports. A 15-amp circuit breaker helps prevent overloads. The unit is designed for flexible installation with detachable mounting flanges and supports rack, wall, or under-counter mounting, offering versatility for space-limited rooms and equipment-heavy racks.
Best for: mixed-device setups requiring multiple USB charging options and flexible mounting configurations.
Caution: The emphasis on USB charging means the primary power distribution should be measured to avoid exceeding the 15A limit when multiple USB devices draw power concurrently.
StarTech.com 1U 19 Inch 8 Port PDU
The StarTech 1U 8-port PDU offers 8 C13 outlets and a 16A/120V (or 20A/240V) configuration with a 10-foot C19 to NEMA 5-20P cord. It includes a built-in circuit breaker for surge protection and supports EIA-310D-compliant rack installations. This PDU is a solid option for users seeking a balance between outlet count, protection, and rack compatibility.
Best for: compact, high-density rack environments that require reliable protection and straightforward installation.
Caution: It provides fewer outlets than larger PDUs; plan for growing device needs or distribution of power to accommodate future equipment.
CyberPower PDU41004 Switched PDU
The CyberPower PDU41004 combines switching with metering in an 8-outlet, 1U form factor. It provides automatic event notifications and a power control display, enabling remote and local management of outlets. A 10-foot cord connects to a NEMA IEC-320 C14 input, supporting efficient distribution in data centers and network rooms that require proactive power management and alerting capabilities.
Best for: IT rooms needing proactive power control, alerts, and straightforward per-outlet management in a compact footprint.
Caution: This unit is optimized for active management; ensure your network and SNMP or alert systems are configured to utilize its notifications effectively.
Buying Guide: Key Considerations For IEC PDU Selection
- Outlet density and layout: Do you need more rear outlets, front outlets, or a mix? Consider space in your rack and the ease of cable routing.
- Voltage and amperage: Confirm your equipment’s voltage (120V vs 240V) and total current draw. Choose a PDU with a circuit breaker rating that matches your load.
- Metering and control: Do you need per-outlet metering, remote control, or switching? Metered-by-outlet PDUs help monitor consumption; switched PDUs enable power cycling of outlets.
- Redundancy: If uptime is critical, select PDUs with dual feeds or ATS features to minimize single points of failure.
- Form factor and compatibility: Ensure the PDU fits your rack (1U vs 2U) and is compatible with ANSI/EIA rack standards.
- Monitoring and integration: Check if the PDU supports integration with monitoring systems (SNMP, IP address data, alarms) and whether it provides a clear LCD or digital display.
- Safety and certifications: Look for UL-listed or equivalent certifications and surge protection features for equipment safety.
