Power cable IEC-60320 from C13-layered to C14 from 3m

The IEC 60320 standard defines an international set of non-locking appliance couplers for connecting power supply cords to electrical equipment up to 250 V.

The specification ensures electrical and mechanical interchangeability across a wide range of devices. Connectors are designated by even and odd numbers, where odd numbers (C7, C13, C19) refer to the female connector and even numbers (C8, C14, C20) to the male appliance inlet.

Widespread adoption of this standard has enabled global hardware manufacturing efficiency, allowing a single power supply unit to work worldwide by simply swapping the localized cord. In modern data center architectures, the shift toward C19/C20 standards is vital to handle the increased power density of high-performance servers.
