Computer Monitor Power Cable Buying Guide: Detachable vs Built-in
Quick answer / TL;DR: Most modern monitors use a detachable power cable – C13, C5 or C7 – so a replacement is a low-cost, ten-minute job. Identify the inlet, match the family, pick 1.8 m or 2 m, and buy a cord with a regional safety mark. Only built-in leads need a vendor service.
Before buying a computer monitor power cable, one question decides everything: is the lead detachable? On most monitors it is, which makes the purchase a simple cable swap. On a minority – some all-in-ones and a few special panels – it is built in, and the fix is different.
This buying guide covers the detachable families, how to identify the inlet, length selection, and the built-in case, so the order lands right the first time.
First: Detachable or Built-in?
Check the back of the monitor. If a cord plugs into a standard inlet (C14, C6 or C8 shape), the lead is detachable and any matched cord replaces it. If the cable exits the chassis as one continuous piece with no standard inlet, it is built in – the repair path is a vendor service or a matched full-cable assembly, not an off-the-shelf cord.
The Detachable Families, in Buying Order
C13 for the large panels
Panels from 24 inches up, and professional displays, are usually C14-inlet, so the purchase is a C13 cord – the same part as the desktop. If you already keep C13 spares for the tower, you probably already own the monitor cord.
C5 (MIDI) for the compact units
The small rounded trapezoid inlet wants a C5 cord. Compact monitors and some all-in-ones use it; the cord is the same 10 A class in a smaller plug.
C7 (figure-8) for the home-office mainstream
The flat two-pin figure-8 inlet is the most common on home and office monitors. The C7 cord is two-wire with no earth, and it is the part that gets lost most often in desk moves.
| Inlet on the monitor | Cord to buy | Typical length | Price class |
|---|
| C14 (wide rectangle) | C13 | 1.8-2 m | Low |
| C6 (small trapezoid) | C5 (MIDI) | 1.8 m | Low |
| C8 (flat oval) | C7 (figure-8) | 1.5-2 m | Low |
| Built-in lead | Vendor assembly | n/a | Service cost |
Detachable cords in all three families are stocked in 1.8 m and 2 m with the regional wall plug; built-in replacements are handled as service items against the panel model.
Length and the Small Details
Monitors sit close to the outlet or on the desk top, so 1.8 m is the default and 2 m the safety margin. Confirm the cord carries a safety mark for the region and a 10 A rating. Skip the built-in surge module on a monitor cord – the monitor load is small, and the desk surge strip already covers the circuit. If the monitor is on a VESA wall mount, add 30 cm for the cable route around the arm.
Real-World Applications
Desk move: the old C7 went missing – a 2 m C7 from the drawer restores the monitor in minutes. Fleet refresh: the new 27-inch panels are C13, so the existing tower spares cover the screens with zero new stock. Wall-mounted display: a 2 m cord routed behind the mount, with the slack folded, not coiled tight.

Frequently Asked Questions
What should I look for when buying a monitor power cable?
Three things: the inlet family (C14 takes C13, C6 takes C5, C8 takes C7), a 10 A 250 V rating with a regional safety mark, and a length of 1.8-2 m for a normal desk. If the lead is built into the chassis, it is a vendor service item rather than a cable purchase.
Can I use my PC power cable for the monitor?
If the monitor has the same C14 inlet, yes – the desktop C13 cord works directly on it. If the monitor uses the smaller C7 figure-8 or C5 MIDI inlet, it needs that family instead; the plugs are not interchangeable.
How long should a monitor power cable be?
1.8 m is the default for a desk or shelf monitor, 2 m if the outlet is on a side wall or the monitor is wall-mounted behind an arm. Monitors draw little power, so length is about routing comfort, not gauge.
What if my monitor has no detachable power inlet?
Then the lead is built in. Do not cut or splice it. The correct path is a vendor service or a matched full-cable assembly for that panel model – the repair touches the chassis, not just the plug.
