PCIe Power Cables: Reliable and Flexible Power Solutions for Graphics Cards

A PCIe power cable is an essential component in any system running a discrete GPU. Whether you’re powering a single graphics card or a multi-GPU mining rig, the quality, compatibility, and configuration of your PCIe power cables play a critical role in system stability and performance. From high-efficiency server builds to modular PSU setups, choosing the right GPU power cable ensures safe and uninterrupted power delivery to your graphics card.

🔌 What Is a PCIe Power Cable?

A PCI Express (PCIe) power cable connects your power supply unit (PSU) to the graphics card (GPU). While standard PCIe slots on a motherboard can supply up to 75W, most mid-to-high-end GPUs require additional power via 6-pin, 8-pin (6+2), or multiple PCIe connectors. This is where dedicated PCIe power cables come in.

These cables are designed to deliver clean, high-current power (often 18A or more) through low-resistance, high-quality copper wire—typically 18AWG tinned copper conductors for optimal performance and durability.

⚙️ Key Cable Configurations

Our PCIe power cable lineup supports a variety of setups, including:

✔ 6-Pin to Dual 6+2 Pin GPU Cables

Perfect for Ethereum mining rigs or server PSU conversion boards, these cables split one 6-pin output into two 6+2-pin connectors, allowing you to power two GPUs from a single source.

✔ 8-Pin to Dual 8-Pin (6+2) Splitters

Ideal for expanding GPU connections in multi-GPU setups or SLI/CrossFire configurations. These compact 8-pin to 2x 6+2 pin power splitter cables support up to 2x 150W output.

✔ 6-Pin to 8-Pin GPU Adapter Cables

Used when upgrading from an older 6-pin PSU to a newer 8-pin GPU. The 6-pin to 8-pin PCIe cable ensures backward compatibility for modern graphics cards.

✔ Modular PSU GPU Cables (e.g., Corsair RM X Series)

Custom-designed for specific modular power supplies, these high-quality cables offer native PSU compatibility with clean, professional cable management. Examples include 8P to dual 6+2P with 750mm length (600+150mm) and 6P to 4x Molex for legacy hardware support.

🧵 Premium Materials and Construction
