Overview

The Monoprice 135058 Heavy Duty Power Cord is designed for environments where reliable, high-capacity power delivery is non-negotiable. Built with 12 AWG conductors, this 6-foot cable is rated for 20 amps at 125 volts, providing up to 2,500 watts of power throughput. The NEMA 5-20P to IEC 60320 C19 connector configuration is the industry standard for servers, UPS systems, power distribution units, and blade server enclosures that draw more current than a standard 15A cord can safely handle.

Where this cable distinguishes itself from lighter-duty alternatives is in its conductor gauge. The 12 AWG wiring minimizes resistance and voltage drop under heavy loads, which is critical for maintaining stable power to sensitive server hardware. Monoprice backs the cord with their Lifetime Warranty, and their in-house technical support team is available for compatibility questions. For data center managers and IT professionals replacing OEM cords or upgrading infrastructure, this is a straightforward, well-priced solution that meets the electrical demands of modern high-draw equipment.

Key Features

This Monoprice heavy-duty extension cord features 12 AWG conductors suitable for high power connections, making it a reliable solution for large server applications that require a higher-rated, heavier-gauge Cable.

This cord can be used to connect a server, router, network switch, or blade server enclosure to an Uninterruptible power supply system or power distribution unit, or to replace or upgrade the standard power cord provided by the device's Manufacturer.
