Extension Cable for 16-Pin GPU Power

This 17.7-inch extension converts a 16-pin (12+4) male connector to three 8-pin (7+1) female connectors. It is designed for graphics cards that use the 16-pin PCIe 5.0 power interface, such as RTX 3090 Ti, 4080 and 4090 models. The cable uses 16AWG tinned copper wire inside a nylon braided jacket.

Cable Combs and Pre-Bent Design

Three included cable combs let you align the individual wires for a tidy, uniform appearance inside the case. The pre-bent shape and ultra-soft materials reduce strain during routing and help the extension sit flush against other components. This makes clean cable management easier without forcing sharp bends.

Check PSU Modular Cables and Clearance

Verify that your power supply provides the required 8-pin modular cables to feed the three female ends of this extension. Remember this is an extension only; it must not be plugged directly into the PSU. Ensure your case has enough room for the 17.7-inch length and the added connector bulk near the graphics card.

Questions about this item

Will the 16AWG tinned copper wires or nylon braid need replacement after long-term use?

The 16AWG tinned copper conductors and high-density nylon braid are built for durability and daily wear, so no scheduled replacement is required under normal conditions.

What is the first limit reached when the 12VHPWR male connector draws sustained power through three 8-pin females?

The cable is rated for PCIe 5.0 operation; the practical limit is the 16AWG wire gauge and connector current capacity, not the extension length.

Does the 17.7-inch sleeved extension add noticeable heat or noise inside the case?

The cable is passive with no active components, so it generates no noise and adds negligible heat beyond normal conductor resistance.
