Product 1: NEMA 5-15P to IEC 320 C19 Power Cord Extension
Brand: Cablelera Store
Length: 6 ft
Format: 14AWG, 15A, 125V
This cord is built specifically for devices with an IEC 320 C19 inlet. It provides a reliable 125V, 15A connection ideal for servers, UPS units, and PDUs that require a C19 interface at standard data-center voltage. It is not compatible with C13 inlets and should not be used with devices needing 20A or higher current. The 14AWG conductor design offers sturdy performance for typical data-center loads while maintaining safe, compliant electrical characteristics.
Key features include a dedicated C19 inlet compatibility, a clearly stated electrical rating, and a focus on safe operation within the equipment’s specified limits. This makes it a straightforward option for upgrading or extending C19-equipped equipment where a longer or more flexible run is needed.
Product 2: Heavy Duty Power Cord – NEMA 5-20P to C19
Brand: Monoprice Store
Length: 6 ft
Format: 12AWG, 20A, 2500W, 125V
Designed for high-power server applications, this heavy-duty extension cord uses 12 AWG conductors to support higher current demands. It connects NEMA 5-20P outlets to IEC 60320 C19 inlets, making it suitable for servers, routers, network switches, and blade-server enclosures connected to a UPS or PDU. It’s compatible with higher-current equipment at 125V and benefits from Monoprice’s lifetime warranty, which offers added assurance for critical deployments. The thicker gauge enhances durability and reduces voltage drop on longer runs.
Considerations include ensuring that the connected devices do not exceed the cord’s 20A rating and that the receiving equipment is compatible with C19 inlets. This option is well-suited for data-center rack circuits and higher-powered network hardware requiring more robust cabling.
Product 3: NEMA 5-15P to C19 Power Cord (3.2 ft / 1 m)
Brand: —
Length: 1 m
Key description indicates a practical adapter-style cord connecting devices with C20 and NEMA 5-15R power connectors. It is RoHS compliant, UL listed, and uses 100% copper conductor with a VW-1 fire rating. This 3-conductor power cable provides a standard 125V supply and is suitable for shorter runs where a compact, flexible solution is needed for PDUs, UPSs, or gear with C19 inlets.
When selecting this cord, verify that the devices involved require a C19 inlet and that the overall assembly remains within standard electrical safety guidelines. It offers a versatile option for compact rack setups or limited-space configurations.
Product 4: StarTech.com 10ft Heavy Duty Power Cord
Brand: StarTech.com Store
Length: 10 ft
Format: 14AWG, 15A, 125V
This heavy-duty cord is designed for workstations, home offices, and data-center equipment requiring a reliable C19 connection. It features fully molded strain-relief connectors for durability and UL listing (UL62 & UL817), with a VW-1 fire rating for added safety. The 10-foot length offers flexibility for equipment mounted in racks or under desks while delivering a solid 125V, 15A capacity for PDUs and network gear.
Important considerations include ensuring the connected devices’ inlets are compatible with C19 and that the chosen length aligns with your rack or workspace layout. The StarTech cord provides a robust option with strong safety certifications and a durable construction.
Product 5: Heavy Duty Power Cord – NEMA 6-20P to C19
Brand: Monoprice Store
Length: 6 ft
Format: 12AWG, 20A, 250V
Designed for high-performance equipment requiring higher current than standard C19 cords, this cord pairs a NEMA 6-20P with a C19 inlet. It is suitable for power-hungry servers, network devices, and data-center hardware that operate at higher voltage (250V) and amperage. The 12AWG conductors support reliable power delivery with reduced voltage drop over the 6-foot run. This option complements data-center setups where 20A circuits feed PDUs or servers that demand greater current than typical 15A C19 cords provide.
When evaluating this cable, confirm that your power infrastructure and equipment support 250V operation and that inlets on the devices match the C19 receptacle. The Monoprice solution adds capacity for demanding gear while maintaining standard C19 compatibility.
Buying Guide: C19 Connector Power Cords — Key Purchase Considerations
- Inlet compatibility: Verify that your equipment uses an IEC 60320 C19 inlet and that the cord’s plug and receptacle match the device and outlet requirements (NEMA 5-15P, 5-20P, or 6-20P).
- Current rating: Choose a cord with an amperage that meets or exceeds the connected equipment’s draw. Common options include 15A and 20A cords; never exceed the device’s rating.
- Conductor gauge: Thicker gauges (e.g., 12 AWG) support higher current and reduce voltage drop, useful for PDUs or racks with multiple devices. For typical 15A loads, 14 AWG is often sufficient.
- Length and routing: Select a length that minimizes excess slack while avoiding tension on connectors. Longer cords can add impedance and risk tripping, but are necessary for certain rack layouts.
- Durability and safety: Look for UL listings, VW-1 or equivalent fire ratings, and molded connectors with strain relief. These features improve longevity in data centers and busy office environments.
- Electrical environment: In data centers, consider whether 125V or 250V operation is standard in your rack or room. Ensure the cord’s rating aligns with the facility’s electrical infrastructure and the equipment’s requirements.
- Brand and warranty: Reputable brands often offer longer warranties and clearer safety documentation, which can reduce risk in mission-critical deployments.
- Compatibility caveats: Some cords are designed strictly for C19 inlets and should not be used with C13 or higher-current devices. Always confirm compatibility before installation.
- Maintenance and replacement: For aging racks, keep spare cords with similar gauges and lengths to preserve performance consistency and simplify replacements when needed.
