Overview

The Monoprice 139781 is a 6-foot, 18AWG IEC 60320 C13-to-NEMA 5-15P power cord rated for 10A at 125V — translating to 1,250 watts of continuous load capacity. That rating matters: 18AWG is the correct gauge for this connector class, keeping conductor resistance low enough that voltage at the device end stays within tolerance over the full 6-foot run. The grounded three-prong NEMA 5-15P plug ensures proper earth continuity for any equipment that requires it, and the female C13 connector mates with the ubiquitous male C14 inlet found on the overwhelming majority of desktop power supplies, monitors, external storage units, network switches, and A/V equipment.

This 6-pack is built for practical deployment scenarios: outfitting a multi-monitor desk setup, populating a home lab rack, replacing aging OEM cords in an office, or simply having spares on hand for a studio or production environment with multiple powered peripherals. The cords ship ready to use with no configuration required. They are not a performance component — there is no measurable benefit to premium cable material at this load and length — so the engineering decision here is simply whether the gauge, rating, and connector are correct for the job. At 10A/125V on a 6-foot 18AWG run, they are.

Key Features

Works with most PCs, monitors, scanners, and printers.

Connect your computer, monitor, power adapter, or other device with a male IEC 60320 C14 panel connector to a standard US AC wall outlet.

The power cord features a standard, grounded NEMA 5-15P plug on one end and an IEC 60320 C13 connector on the other end.

Simply mate the female C13 connector with the male C14 connector on your device or power adapter, then plug the NEMA connector into a nearby AC power outlet, UPS, or other AC power source

These cables are designed to carry up to a 10 amp, 125 volt load.

Pros & Cons

👍 Pros

  • Rated to 10A/125V (1,250W continuous), which comfortably covers desktops, monitors, and most peripherals without operating at the edge of the cord's thermal limits.
  • 18AWG conductor maintains low resistive losses over the full 6-foot length, preventing the voltage sag you'd see in undersized cable.
  • C13-to-NEMA 5-15P is the dominant standard for IT and AV equipment, meaning these cords are immediately compatible across virtually any device in a modern workstation or home lab.
  • 6-pack consolidates procurement — one order replaces cords for an entire desk setup or small rack without leftover inventory.
  • Grounded three-prong design provides safety continuity for any equipment that requires or benefits from an earth ground connection.

👎 Cons

  • 18AWG caps usable load at 10A — high-draw laser printers, server PSUs, or workstation power supplies pulling above that threshold need 16AWG or heavier cable.
  • C13 connector only — these cannot mate with C19 sockets found on high-current server and rack PDU equipment, which is a hard incompatibility for dense rack deployments.
  • Available in black only, which limits color-coding in environments where cable identification by color is part of the cable management scheme.
  • No right-angle plug variant — in tight wall-outlet or power-strip installations, the straight NEMA plug can be awkward to seat without blocking adjacent outlets.

Frequently Asked Questions

Yes, provided the UPS or PDU has IEC 60320 C14 input sockets — which is the standard on virtually every UPS, APC unit, and rack PDU sold for IT use. The NEMA 5-15P end plugs into any standard US three-prong outlet or outlet strip rated for the load.
The C13 connector is the universal standard for desktop computers, monitors, network switches, external storage units, laser printers, and most A/V receivers. If your device has a three-pin "kettle plug" style socket, it's a C14 — and these cords mate directly to it.
18AWG is rated for continuous 10A at 125V — that's 1,250 watts of capacity, which covers the vast majority of desktop systems, monitors, and peripherals. If you're running a high-draw workstation PSU pulling sustained loads above 10A, step up to 16AWG or 14AWG instead. For everything else, 18AWG is appropriate.
No. The NEMA 5-15P plug is a North American standard only. International use requires a country-specific plug standard. Do not use these with voltage converters unless you have confirmed the downstream device and cord rating are compatible.
The 6-pack is specifically practical for multi-monitor setups, small server closets, home lab racks, or office deployments where you're powering several devices at once. Buying individually at this spec costs significantly more per cord for identical performance.
