GPU backplate plate kit Alphacool LYNK+ 5090 — silver finish, backplate mounting accessory

The Alphacool LYNK+ 5090 Plate Kit in silver finish is a GPU backplate accessory designed to attach to compatible graphics cards. It serves as a protective and stabilising element for GPU PC builds, offering an additional rigid surface behind the graphics card that helps prevent PCB flex, supports bracket stability and contributes to an organised appearance for custom water-cooling or modding projects.

Advantages

The silver-finished metal plate improves structural support and reduces PCB bending when cards are mounted in large cases or under heavy coolers. As a passive component it helps distribute contact pressure evenly and provides a clean, uniform surface that complements custom loop fittings and visible card areas. Installation avoids modification of the GPU PCB when a compatible mounting layout is present, and the plate is lightweight while providing durable mechanical protection during assembly and transport.

Suitable for

• Custom water-cooling builds where a clean backplate surface is desired
• GPU modding and visual upgrades in windowed PC cases
• Systems requiring additional rear-side protection for the graphics card PCB
• Setups that need to minimise PCB flex and improve bracket stability

Key specifications

• Material: metal plate with silver surface finish
• Function: rear GPU mounting plate for protection and stabilisation
• Compatibility: designed for use with compatible graphics cards and mounting layouts
• Weight: lightweight design for minimal additional load on the card
• Finish: silver-coloured surface intended for visual integration in custom builds

How to use

Confirm compatibility between the plate kit and your graphics card model or mounting holes before starting. Power down the system and disconnect power cables, remove the graphics card following standard safety procedures, then align the plate with the card’s rear mounting points. Secure the plate using the supplied screws or fasteners according to the kit instructions, ensuring even torque on all fasteners to avoid stress on the PCB. Reinstall the graphics card in the PCIe slot and reconnect power. For water-cooling installations, verify clearance with blocks, fittings and tubing before finalising assembly.

Usage recommendations

Use the backplate in conjunction with manufacturer-recommended mounting hardware and avoid overtightening screws. Check clearance near water-cooling components and ensure the plate does not interfere with contact points on custom blocks. Periodically inspect the fasteners for secure fit after initial use or transport.
