ASUS Graphics Processing Units (GPUs) Utilize Gyroscopes to Detect and Alert Users About Potential Sagging Components.
The growth in size of video cards (GPUs) over the years, akin to CPU coolers, has become noticeable, with the ASUS ROG Astral RTX 5090 card being a prime example. The PCIe slots these cards plug into were not initially designed to accommodate such substantial weight. The increased heft, of course, is subject to gravity's pull.
To tackle this issue, the ASUS ROG Astral RTX 5090 has integrated a Bosch Sensortec BMI323 inertial measurement unit (IMU), offering an accelerometer and angular rate (gyroscope) measurements, as detailed in articles published by Videocardz [1]. This moves beyond simple anti-sag brackets, providing structural support to the top of the GPU where it isn't usually secured.
However, the weight of the air-cooled model, clocking in at over 6 pounds (3 kilograms), appeared to exceed the bracket's capabilities. The resulting software alerts users when the GPU reaches a specified sag angle, allowing them to either shut down the system for readjustment or anticipate imminent dislodgement.
Vertically mounting the GPU at a 90° angle is another solution, reducing stress on the PCIe slots and potentially lowering GPU temperatures by 3–5°C [2]. Products like the Cooler Master MasterAccessory Vertical GPU Holder Kit V3 and GAMEMAX GPU-192 BK offer robust support for heavy GPUs [1][2]. However, this method necessitates high-quality PCIe riser cables to maintain signal integrity, with cheap or low-quality cables potentially leading to system instability and visual artifacts [4].
GPU sag brackets provide additional support without requiring vertical installation. They are simple to install and do not necessitate reconfiguring the case. However, they may not address airflow issues as effectively as vertical mounting [3].
High-quality PCIe riser cables are vital for vertical mounting setups, ensuring system stability [1]. For future-proof solutions, consider PCIe 5.0 models [4]. Yet, even the best cables can induce issues over time, such as system instability [4].
Although ASUS briefly introduced a feature to detect GPU sagging, it has since been removed, suggesting users may need to rely on manual adjustments to prevent sagging [3].

The ASUS ROG Astral RTX 5090 incorporates a Bosch Sensortec BMI323 inertial measurement unit (IMU) for structural support, using accelerometer and angular rate measurements to tackle the issue of GPU sagging. On the other hand, high-quality PCIe riser cables are essential for vertical mounting setups, as they help maintain system stability and prevent visual artifacts.
