Key Features

6 Pin to 8 Pin PCIe Adapter: Connect a 6-pin male PCIe power plug from a compatible power supply to the 8-pin PCIe power input on a supported graphics card. Confirm the connector types before ordering
For Compatible Low-Power GPUs: Use the PCIe power adapter only when the power supply and its 6-pin PCIe connection provide sufficient power for the graphics card. Check the documented power requirements of the PSU and GPU before installation
8 Pin to 6 Pin PCIe Adapter: The GPU power adapter changes a 6-pin PCIe connection into an 8-pin connector but does not increase the PSU wattage, current capacity, or available power. It is not suitable for bypassing GPU power requirements
Secure PCIe Connections: The 8-pin male connector features a locking latch, while the 6-pin female connector uses a keyed housing to support proper alignment and help prevent accidental disconnection
Convenient 2-Pack: Use the two PCIe adapter cables with separate compatible systems or keep one as a spare. Compatible with select Gigabyte, Radeon, and Sapphire graphics cards with an 8-pin PCIe power input. Check the GPU power requirements before use. Not compatible with CPU/EPS 8-pin ports
