EK-Quantum Vector Xtreme RTX 3080/3090 Backplate - Black is a CNC machined retention backplate made from black anodized aluminum, that fits all EK-Quantum Vector Xtreme RTX 3080/3090 water blocks.
The backplate covers the whole length of the graphics card's PCB, serves as an aesthetic add-on, and also provides passive cooling for the backside of the voltage regulation module (VRM), the GPU core, and rear-mounted VRAM on the 3090 cards.
