The Cooler Master MasterAccessory ARGB GPU Support Bracket holds a graphics card level so it cannot bend or sag over time, protecting the card and the motherboard it sits in. Tempered glass and ARGB lighting mean it also reads as part of the build rather than a hidden brace. Multiple orientations suit most computer cases, and installation needs no tools.

Tempered glass and ARGB lighting mean it also reads as part of the build rather than a hidden brace. Multiple orientations suit most computer cases, and installation needs no tools.

The bracket is built from CNC-machined tempered glass, which gives it the rigidity to carry large, heavy graphics cards while taking stress off the PCI-e slot. Addressable RGB with edge-lighting technology runs through the glass for a vibrant glow you can tune to match the rest of the build, and the universal support arm's adjustable sliding mechanism suits a range of PC cases.

As graphics cards grow larger and heavier, the load they place on the PCI-e slot increases, and that stress is what eventually damages the slot or the card's PCB. The MasterAccessory bracket braces the card at its weight-critical points, so the mass is carried by the case floor rather than by the connector and the retention clip alone.

Installation is 100% tool-less, using simple adjustment mechanisms and a magnetic base that holds the bracket securely in position while you set the height. CNC-machined rails in the tempered glass surface carry the ARGB lighting through the support, and the lighting can be switched off entirely for a minimalist look if you would rather the bracket disappeared into the build.

Two support arms with different orientations are included, letting you brace the card at the tail-end or along the side nearest the side panel, whichever your case allows. The arm slides and locks to fit graphics card widths from 41mm to 171mm, and durability testing shows the support carries heavy-duty GPU weights without failure.
