Eaton Tripp Lite 2ft Power Cord — 15 Amp, 14 AWG
The P007-002 cord is a heavy-duty 3-prong power cable rated for 15 amps with 14 AWG conductors. This enables a safe connection for devices that require higher current draw and aligns with standard household outlets for versatile deployment. The 2-foot length helps reduce clutter in tight server racks and equipment closets. Compatible with a wide range of devices, including PCs, monitors, printers, and other peripherals, this cord is suitable for small-scale server rooms or switch closets where space is at a premium.
Cable Matters 6ft C14 to C13 Power Cord
This durable jumper cable connects servers, PDUs, and UPS systems with IEC 60320 C14 and C13 connectors. The 6-foot length provides flexible routing in crowded racks while maintaining a stable, reliable power link. Rated for 10A at 125V, it supports common server equipment and workstations, and its sturdy construction helps protect sensitive hardware from accidental unplugging or strain. A practical choice for mid-sized data centers or server rooms with PDUs in adjacent racks.
StarTech 10ft Power Cord — NEMA 5-15P to C13
StarTech’s 10-foot power cord provides a reliable, UL-listed C13 connection from a standard NEMA 5-15P outlet. The 18 AWG cable is fully molded with strain relief to improve durability in high-traffic server rooms. Rated for 125V and 10A, this cord suits workstations, servers, printers, and other IT equipment where extra reach is needed. The robust build and tested safety credentials help ensure consistent power delivery in data center environments.
Eaton Tripp Lite 3ft Power Cord — 15 Amp, 14 AWG
The P007-003 is a compact, heavy-duty 3-prong power cord with 14 AWG conductors. Designed to deliver 15 amps, it provides a safety margin for high-powered devices, matching standard household amperage needs. The 3-foot length makes it suitable for mid-rack deployments or tight spaces between devices and outlets. It is compatible with servers, monitors, printers, and other equipment from major brands.
Cablelera IEC320 C20 to C19 Power Cord — 15 ft
Designed for enterprise-grade IT equipment, this Cablelera cord uses IEC C20 and C19 connectors for high-power servers and PDUs. Its 12 AWG conductors and 20A/250V rating support demanding loads typical in data centers. Note that it does not connect to wall outlets, so it’s intended for equipment racks and power distribution setups where IEC connections are standard. The longer 15-foot length helps reach distant outlets or PDUs across rows of equipment.
Buying Guide: Key Purchase Considerations For Server Power Cables
- Connector compatibility: Ensure the plug and receptacle match your equipment (NEMA 5-15P to IEC C13, IEC C14 to C13, or IEC C20 to C19) and the device’s power requirements.
- Conductor gauge and current rating: For servers, 14 AWG conductors supporting up to 15A are common, offering safety margins for high-load devices.
- Cable length: Choose a length that minimizes clutter but allows flexible placement across racks and PDUs without excessive slack that could snag or overheat.
- Durability and build: Look for molded strain relief, UL listings, and robust jackets to withstand frequent plugging/unplugging and data-center environments.
- Intended environment: IEC C20/C19 cords suit enterprise power supplies and PDUs, while NEMA-to-IEC cords are common in small-scale server rooms and office settings.
- Compatibility with PDUs and UPS: C14-to-C13 cords are ideal for connecting servers to PDUs, which is a frequent need in rack deployments.
- Safety certifications: UL-listed or equivalent certifications help ensure safe operation in critical equipment environments.
- Color and labeling: In a data center, uniform color-coding can simplify cable management and fault identification.
- ETL/UL compliance and temperature ratings: Consider cords rated for typical data-center temperatures, especially in non-climate-controlled rooms.
When assembling a server rack, it is helpful to map out each device’s outlet needs, consider future expansion, and align power cords with PDUs to minimize power distribution complexity. Selecting multiple lengths and plenty of spare cords can improve resilience and maintenance efficiency in busy data centers.
