PSUs with a wattage of 1000W or more are primarily targeted at users with extreme computing requirements, such as hardcore enthusiasts, professional content creators and individuals involved in specialised applications such as scientific computing and deep learning. These users often build high-end systems with multiple top-of-the-range graphics cards. The intense processing power demanded by such setups requires a 1000W or higher PSU to ensure stable power delivery and prevent system instability or crashes during intensive workloads or gaming sessions.

In addition, professionals working in fields such as video production, 3D rendering and animation often require the processing power offered by multi-GPU setups and high-end CPUs. A 1000W or higher power supply can provide the necessary headroom to support these demanding configurations, resulting in faster render times, smoother workflows and increased productivity.
