Product details

Overview

Meet the JOYJOM 16Pin PCIe 5.0 to 3x8Pin power adapter, designed for modern RTX 40xx graphics cards. The sleeved black cable offers a clean look in high-end builds, while the 90-degree angle helps manage space in compact cases. This cable aims to provide a flexible, reliable power path for demanding GPUs without forcing a complete rewrite of your power setup.

Design and compatibility

The 16-pin (12+4) connector pairs with three 8-pin PCIe ports on your power supply. Two orientation options exist (Type A and Type B); select the one that aligns with your motherboard and GPU layout. The right-angle variant keeps cable runs tidy and reduces strain on both the input port and the cable, potentially extending the life of your setup.

Power delivery and build quality

Crafted with 16AWG copper conductors, the cable supports up to 600W of peak power, meeting the needs of high-end GPUs. Terminals are alloy copper and tinned for durability and stable current delivery. The sleeved black jacket adds a premium look while helping manage clutter and EMI in busy builds.

Usage tips and compatibility notes

Before installing, ensure you have three free 8-pin PCIe connectors on your PSU. This extension won’t function with fewer than three connectors connected. Always verify the GPU interface and the correct orientation (Type A vs Type B) using the product images and your GPU model.
