The A-PC7900XTXDEVIL-X is a full-coverage water block built specifically for the PowerColor Red Devil Radeon RX 7900 XTX 24GB. The cold plate is ultra-high-purity copper with nickel electroplating to resist oxidation, topped with a PMMA acrylic cover, and the backplate is anodized aluminum kept out of the coolant path. Microchannel routing cools the Navi 31 GPU die, GDDR6 memory, and VRM phases simultaneously through G1/4 inlet and outlet ports, and a high-flow design supports parallel or series multi-card loops. A pre-installed 5V 3-pin addressable RGB (RBW) strip syncs with mainstream A-RGB headers.
Q: Which card is this block compatible with?
A: PowerColor Red Devil RX 7900 XTX 24GB only. The Hellhound, Reference, and Liquid Devil variants use different PCB layouts.
Q: What materials are used?
A: Ultra-high-purity copper with nickel electroplating, PMMA acrylic top, and an anodized aluminum backplate not in the coolant path.
Q: What is the block length?
A: Approximately 157.46mm. Confirm chassis clearance before ordering.
Q: What lighting standard does it use?
A: 5V 3-pin addressable RGB (RBW). A 12V 4-pin RGB header will destroy the LED strip.
Q: What is in the box?
A: Full-cover GPU block, backplate, two G1/4 stop plugs, installation screwdriver, lighting sync cable, and a Bykski thermal pad set.
