StarTech.com 10ft Computer Power Cord
This 10-foot cord uses NEMA 5-15P to IEC 60320 C13 connectors, a common setup for servers and workstations. It is UL listed and fully molded for durability in data centers or office server rooms. The 18AWG conductor supports typical server and peripheral power needs without excessive bulk.
Best for: IT rooms needing a reliable, longer cord for placement flexibility. Better for: setups where the power outlet is distant from equipment racks. Choose this if: standard C13 devices are in use and you need a longer, sturdy option. Caution: 10 ft may introduce slight voltage drop for high-power servers under peak load.
Eaton Tripp Lite P007-006 6ft Power Cord
Heavy-duty 6-foot cord with 14 AWG wiring delivers up to 15A, suitable for servers, desktops, and network equipment. The three-prong plug-to-C13 configuration matches standard power outlets and many rack-mounted devices. Fully molded connectors reduce wear in hot data-center cabinets.
Best for: environments where higher amperage and robust construction are essential. Better for: servers and workstations requiring consistent power delivery. Choose this if: you want a durable cable with generous length. Caution: bulkier than thinner cords, may require cable management in tight racks.
Cable Matters 18 AWG 6ft (2-Pack) Power Cord
This 2-pack provides a reliable C13 to C14-compatible connection suitable for PDUs, servers, and network gear. Rated for 10A and 125V, the 18AWG wires strike a balance between flexibility and safety, offering cleaner cable management in dense racks.
Best for: data-center racks needing multiple spare cords with consistent sizing. Better for: server rooms with tight cable runs and standardized equipment. Choose this if: you need matching lengths for multiple devices. Caution: 18AWG may be near its limit on high-power servers under heavy load; consider heavier-gauge cords for critical power paths.
REBUILD SKILLS 10Ft Universal Power Cord
This bulk-friendly 10A-rated cord uses IEC C13 to NEMA 5-15P with 18AWG wire. It supports desktops, monitors, and many IT devices in bulk purchasing scenarios. The 18AWG conductor is common in office-grade devices and moderate power loads.
Best for: IT departments seeking standardized cables across many devices. Better for: mixed equipment environments with common C13-powered gear. Choose this if: you require a cost-effective multi-pack. Caution: not ideal for high-wattage servers; ensure device power needs align with 10A rating.
Cable Leader 6ft 14AWG Power Cord
This 6-foot, 14AWG power cord provides robust current capacity for standard servers and peripherals, featuring a NEMA 5-15P to IEC C13 connector set. CSA Approved and designed for reliable performance in North American power environments.
Best for: environments prioritizing heavier gauge for safety and stability. Better for: server rooms with mixed equipment under steady loads. Choose this if: you need durable construction and CSA certification. Caution: 14AWG may be less flexible in very tight rack installations compared to thinner cords.
Buying Guide: Key Purchase Considerations For Server-Grade Cables
- Connector compatibility: Most servers use IEC C13 or IEC C19 inlets. Verify whether your equipment uses C13, C14, C19, or a C20 inlet, and match to the corresponding plug type (NEMA 5-15P in the U.S.).
- Current rating: Servers can draw substantial current; select cords rated for at least 10A, with 14AWG or thicker for high-load devices. For power-hungry equipment, consider 12AWG or 14AWG with higher amperage ratings.
- Length and management: Longer cords offer flexibility but increase clutter. Choose lengths that minimize excess slack in rack installations and align with UPS or PDU placement.
- Durability: Look for fully molded connectors and thick jackets for data-center environments. Cables with strain relief tend to last longer under frequent plugging and unplugging.
- Bulk purchasing: Data centers and IT departments often standardize on a single cable type. Bulk packs reduce per-unit cost and simplify inventory management.
- Safety certifications: UL, CSA, and similar approvals indicate compliance with electrical safety standards important in enterprise environments.
- Future-proofing: If your rack devices may upgrade to higher-power loads, consider cords with higher current ratings and sturdier construction to avoid replacing them soon.
Frequently Asked Questions
- What is the most common server cable type? — The most common are IEC C13 to NEMA 5-15P cables, used for many servers, PDUs, and monitors in the U.S.
- Do I need heavier gauge cords for servers? — Yes, if your servers draw high current or are in dense racks; 14AWG or thicker is generally safer for sustained loads.
- Can I mix different brands for my server rack? — Yes, as long as connector types and ratings match your equipment, mixed brands can work, but uniformity simplifies management.
- What about cables for IEC C19 inlets? — IEC C19 cables are designed for higher-power equipment. Ensure the device inlet and outlet match (C19 to appropriate plug).
- Are bulk power cords risk-free for data centers? — Use UL-listed or CSA-approved cables, and follow your facility’s electrical standards to minimize downtime.
- How long should a server power cord be? — Choose a length that fits your rack layout and UPS/PDU placement while minimizing excess slack.
