Backplate

pc

A backplate is a structural component mounted on the rear of a graphics card for physical support and heat dissipation.

expanded

In a personal computer, a backplate is utilized to enhance the mechanical support of a graphics card and can aid in thermal management by dissipating heat away from the circuit board. This piece is typically made from aluminum or stainless steel, providing both rigidity to prevent PCB flexing under the weight of the cooling components and acting as an additional surface area for cooling.

examples

The EKWB EK-Quantum Vector² Backplate utilizes a CNC-machined aluminum design to offer structural support and improve thermal performance.

Found in high-performance gaming setups, the EK-Quantum Vector² Backplate is commonly used with EKWB's GPU water blocks to ensure even weight distribution and improve heat dissipation from the GPU.

The ASUS ROG Strix LC's backplate provides necessary rigidity for the NVIDIA GeForce 4090 card, while also acting as a passive heatsink, enhancing heat dissipation by approximately 3% compared to models without a backplate.

Utilized in gaming desktops where maintaining lower GPU temperatures is crucial, the ROG Strix LC's backplate contributes to smoother performance under extended load.
