GoodConnections 5.25 inch 4-Pin Molex Power Extension Cable, Internal, 20cm (5021-4VL)

Internal PC builds often face cramped layouts where the power supply's Molex connectors fall just short of reaching an older hard drive, optical drive, or case fan. This 20 cm extension cable bridges that gap without forcing you to reroute cables or buy a new PSU. It simply plugs between the existing 4-pin Molex plug and the device, giving you the extra length needed for a clean, stress-free connection.

Who is it for

This cable is ideal for PC builders, upgraders, and repair technicians working with legacy components that still rely on 4-pin Molex power. It's perfect for systems with bottom-mounted power supplies, full-tower cases, or custom cable management where stock cables are too short.
