Standard 5ft Power Cord for Electronics
Best for: small to mid-size server rooms, workstations, or monitors needing a simple, reliable power link. This 5-foot, 3-prong cord uses a universal 125V, 10A rating and a fully molded design for durability. It’s a straightforward replacement for worn or lost cords in a mixed gear environment.
Why chosen: Its length suits desks or low-profile racks, and the fully molded construction supports frequent unplugging and plugging without wear. The 3-pin design provides a solid ground connection for common electronics.
Caution: Not ideal for high-density racks where longer runs reduce clutter or where higher amperage is required; ensure your devices stay within 10A and 125V ratings.
Cable Matters 2-Pack 18 AWG 10A C14 to C13
Best for: servers, PDUs, and UPS setups in data centers where a stable C14 to C13 link is needed and cable clutter minimized. This 6-foot jumper is ideal for tight rack environments and daisy-chaining with other equipment.
Why chosen: The IEC 60320 C14 to C13 connection delivers a dependable power path for critical devices, with a 10A / 125V rating suitable for most server peripherals. A two-pack helps maintain uniform cabling across multiple rack positions.
Caution: Check PDUs and UPS compatibility; mismatched inlet/outlet types can require adapters in some installations.
[UL Listed] Cable Matters 16 AWG 3 Prong 10ft
Best for: desktops, larger monitors, printers, and other gear that sit further from outlets. The 16 AWG wire size supports typical power needs with improved reliability over thinner cords.
Why chosen: This 10-foot option balances reach and flexibility for office or small data rooms. It’s a practical upgrade when a standard shorter cord isn’t sufficient.
Caution: Some high-powered servers or equipment drawing above 10A might benefit from heavier gauge (14 AWG) cords for extra headroom.
UL Approved 10ft Universal Power Cord — 18AWG
Best for: IT departments and data centers seeking bulk, standardized cabling across multiple devices. The bulk 5-pack option provides uniformity in large deployments.
Why chosen: It supports common hardware with C13 to C19 compatibility in many enterprise setups, featuring UL approval and a grounded 3-prong design for safety in demanding environments.
Caution: This cord is designed for C13 devices; verify inlet type before use in servers or PDUs with different connectors.
StarTech.com 10ft Power Cord, C13 to NEMA 5-15P
Best for: workstations or servers that require longer reach between equipment and power outlets. This 10-foot, 18 AWG cord is UL listed and designed for reliability in busy offices and server rooms.
Why chosen: Its fully molded connectors and copper conductor ensure a stable power path with good resistance to wear in daily use. The 10-foot length helps reduce clutter in larger desks or racks.
Caution: If you need higher current than 10A, consider a heavier gauge option to maintain a comfortable safety margin.
Cablelera NEMA 5-15P to IEC 320 C19 Power Cord
Best for: devices with IEC 320 C19 inlets, such as certain servers and PDUs that need a C19 connection. The 6-foot length fits most data rooms with mid-height racks.
Why chosen: It clearly targets C19-inlet equipment and pays attention to the rated 15A/125V, ensuring compatibility in common enterprise settings.
Caution: Not compatible with C13 inlets; do not use with 20A devices or higher current requirements.
Eaton Tripp Lite 6ft 15A Power Cord
Best for: PCs, monitors, laptops, printers, and other office-grade devices that require a robust 15A supply. The 6-foot length reduces clutter while offering ample reach.
Why chosen: The 14 AWG construction provides a safe power path for devices with higher power draws, aligning with typical IT and office equipment needs.
Caution: For longer rack runs, a 10A cord may suffice, but heavier loads may benefit from a thicker gauge than typical 18 AWG cords.
Buying Guide
What connector should I choose? Most servers and PDUs use IEC 60320 C13 or C14 connections with a NEMA 5-15P plug for standard US outlets. Confirm inlet/outlet types on your equipment before purchasing.
How important is gauge and amperage? Higher gauge (lower AWG number) supports more current with less heat. For typical servers, 14 AWG or 16 AWG cords handle 10–15A, while some devices may require 14 AWG for a safety margin.
What about length and organization? Longer cords reduce clutter in dense racks but can create excess slack. Choose lengths that minimize tangling and use matching lengths for cleaner installations.
What about bulk purchases? IT departments may benefit from multi-packs to standardize across devices, simplifying stocking and reducing downtime caused by cable mismatches.
Are there safety certifications to look for? UL listing and CSA approvals indicate compliance with safety standards. Grounded three-prong designs are common for equipment protection in office and data-center environments.
FAQ
- Can I use a standard computer power cord with a server? Yes, if the server uses a compatible IEC C13 inlet and the cord matches the device’s amp rating. Verify both inlet type and current draw.
- What length should I choose for a server rack? Prefer lengths that minimize excess slack while reaching PDUs or UPS without strain. 6–10 ft is common for many racks.
- Is 18 AWG enough for servers? For typical equipment drawing near 10A, 18 AWG may be marginal. Higher-gauge cords (16–14 AWG) provide more safety margin for continuous use.
- Do I need UL or CSA listed power cords? In business or data-center environments, yes. These certifications indicate compliance with safety standards.
- Can I mix brands for my data center? Yes, as long as the connectors, gauges, and ratings are compatible with each device and follow your organization’s cabling standards.
- What should I do if a cord doesn’t fit? Do not force connectors. Check inlet shapes and ensure there is no damage to the receptacle or plug; replace with a compatible cord.
