FormulaMod 16AWG 12VHPWR to 4x8Pin PCIe 5.0 Extension Cable 17.7in Blue

FormulaMod 12VHPWR Extension Cable

This FormulaMod 16AWG extension cable connects a 12VHPWR male connector to four 8-pin female connectors, adding 17.7 inches of reach for RTX 4090, 4080, 4070 and 3090 graphics cards. It is designed for builders who need to route power around large coolers or through tight routing channels. The cable is not a PSU replacement and must plug into an existing modular 8-pin cable set. Buyers without modular 8-pin cables on their power supply cannot use this product.

Check PSU Modular Ports and Cable Layout

Verify that your power supply provides enough modular 8-pin PCIe ports to feed the four female connectors on this extension. Confirm the GPU requires a 12VHPWR (12+4) input and that the existing PSU cables are long enough to reach the extension once it is routed. The extension adds fixed length, so measure the path from PSU to GPU to avoid tension or sharp bends. Systems with non-modular PSUs or insufficient 8-pin outputs are not compatible.

Thermals Noise and Power Handling

The 16AWG tinned copper conductors are rated for the high current draw of PCIe 5.0 12VHPWR connections, maintaining stable delivery under load. A durable nylon braided jacket resists abrasion and heat from nearby components, while three included cable combs keep the four leads aligned for consistent airflow. The pre-bent, ultra-soft construction reduces strain on the GPU connector, helping prevent hotspot formation during sustained gaming or compute workloads.
