A typical graphics card has inbuilt protections to prevent electrical and thermal overload, but running it at the limit day in and day out takes a toll on its lifespan. The resulting heat dissipation also takes the GPU silicon substrate beyond 87☌ (or 189☏). However, pumping more than 200 watts during a typical gaming session taxes the graphics card’s power delivery subsystem.

Most of this electrical energy is then dissipated as heat. But running a ray-traced game at “Ultra” settings will cause it to guzzle power to the tune of hundreds of watts. Give your GPU a light task, and it will sip a small amount of power. Therefore, the performance of a GPU is limited by the maximum power and heat it can handle without damaging itself. Each operation consumes some amount of power, and most of it is dissipated as heat.

What Is GPU Undervolting?Īt the heart of your graphics card lies at least one GPU, which renders images by rapidly switching billions of transistors on and off.

Here’s how you can run your graphics card cooler and prolong its life through GPU undervolting.
