The ASUS ROG Zephyrus G16’s power limit is fixed at 175W by the manufacturer to maintain the device’s portability. This limitation plays a critical role in preserving the laptop’s thermal performance and the longevity of its internal components.

However, a user attempted to exceed these limits using an experimental utility called NvpwrControl. This process pushed the device’s hardware capacity, allowing the total power consumption to reach 215W.

Technical Consequences of Exceeding Power Limits

This process, carried out by Redditor Firm-Age4730, resulted in the RTX 5090 graphics card reaching 185W and the Intel Core Ultra 386H processor reaching 31W of power consumption. Tests conducted in resource-intensive games like Cyberpunk 2077 showed that the system put both components under equal load simultaneously.

Under heavier workloads, the GPU was observed to operate at 160W, while the power allocated to the processor dropped to approximately 13W. This resulted in a significant performance imbalance across the system, preventing the processor from accessing the power it needed.

While removing the power limit theoretically promises higher performance, in practice it led to significant overheating issues. The RTX 5090 graphics card reached a temperature of 84 degrees, only approaching the end of thermal throttling by 3 degrees.

Similarly, the Intel Core Ultra 386H processor reached 95 degrees, only dropping 5 degrees below its maximum operating temperature. Although ASUS is known for using high-quality components in its premium segment devices, the voltage regulator modules, or VRMs, are not designed for such high power draws.

Thermal Limits and Fan Noise

This experimental power increase pushed the device’s cooling system beyond its limits, creating an unsustainable operating environment. Unless the ambient temperature is significantly low, maintaining the Zephyrus G16’s 215W power limit during extended sessions seems physically impossible.

Another striking element in the images is the speed of the cooling fans. The CPU fan spins at 6,700 RPM, and the graphics card fan at 6,800 RPM, reaching a noise level reminiscent of a jet engine.

These high fan speeds significantly negatively impact the user experience, making it impossible to sit at the device without headphones. The heated components and unbearable fan noise clearly demonstrate that these types of slim-designed laptops inevitably have power limitations.

In conclusion, these types of modifications risk the lifespan of the device’s hardware and completely eliminate comfort in daily use. Do you think these kinds of experimental power increases in laptops are worth trying despite the risks involved?
