Overview

A nickel-plated full-cover water block with a black acetal top designed for AMD reference RX 6800 and 6900 XT graphics cards. Features addressable RGB lighting via a standard 5V 3-pin header.

Design and Materials

The block uses a nickel-plated copper base for heat transfer. A black acetal cover encloses the flow channels. This combination resists corrosion and provides a clean, dark aesthetic.

Compatibility

Lighting

Integrated addressable RGB LEDs connect via a 3-pin 5V digital header. Allows synchronization with motherboard RGB software. No separate controller is required.

Included Accessories

Package contains the water block, mounting hardware for the reference PCB, and thermal pads for memory and power phases. Fittings are sold separately.
