Backplate Phanteks PH-GB6900ASSRX

The Phanteks PH-GB6900ASSRX Backplate is a single-piece aluminum backplate designed to fit compatible graphics cards. With a slim 1 mm profile and compact dimensions of 277 mm width and 127.2 mm depth, this backplate provides a rigid, flat surface that improves the visual finish of a build while contributing to passive thermal performance and structural support.

Advantages

The backplate's aluminum construction offers durability and lightweight rigidity, while the black and silver finish gives a clean, professional look that integrates with many system color schemes. Its full-coverage design helps distribute mechanical stress across the PCB, reducing potential bending, and the slim profile minimises added thickness inside the case. The backplate also assists in passive heat dissipation from the rear of the graphics card.

Suitable for

• Upgrading the rear appearance of a compatible graphics card
• Reducing PCB flex and improving card stability in the motherboard slot
• Improving passive thermal dissipation from the card back surface
• Custom PC builds where a black and silver aesthetic is desired

Key specifications

• Material: Aluminum
• Finish: Black and silver
• Profile thickness: 1 mm
• Dimensions (W × D): 277 mm × 127.2 mm
• Design: Single-piece full-cover backplate

How to use

Install the backplate on a compatible graphics card by aligning it with the card's mounting points and securing it using the original fastening hardware or the screws provided with the backplate, if included. Ensure the card is powered off and removed from the system before beginning installation. Verify that the backplate does not obstruct any connectors, cooling components, or case clearance before finalizing fitment.

Recommendations

For best results, confirm compatibility with your specific graphics card model and check clearance inside your case. If reusing original card fasteners, keep torque moderate to avoid damaging PCB components. Combine the backplate with adequate case airflow for optimal thermal behaviour.
