Our Internal ATX Cables category covers ATX power extension and adaptor cables used to connect ATX power supplies to 20-pin and 24-pin motherboard connectors inside the PC chassis, giving flexibility when working with legacy or mixed ATX platforms in standard PC builds.
The range includes 20-pin male-to-female ATX power extension leads for situations where the existing power supply cable will not comfortably reach the motherboard connector, allowing you to extend the connection without modifying the PSU and maintain a tidy internal cable layout.
You can also choose ATX power adaptor cables such as 24-pin female to 20-pin male and 20-pin female to 24-pin male, enabling you to match 20-pin or 24-pin ATX power supplies with compatible motherboards during repairs or upgrades, particularly when repurposing existing enclosures or components.
Selected models, including a 24-pin male-to-female ATX extension cable with a 24 cm lead length, use 18 AWG conductors and a black finish to support neat, consistent cable routing within the system and to simplify planning of motherboard power paths.
These internal ATX cables are suited to system builders, repair technicians and IT teams who need reliable, off-the-shelf options for extending or adapting ATX power connections when working on desktop hardware in workshop, lab or small-office environments.
