Why PSU Specs Matter for Deep Learning

A quality PSU is the foundation of system stability. AI workloads create sustained high power draw during training, unlike gaming's variable loads. Insufficient wattage causes crashes mid-training, wasting hours. High efficiency (80+ Platinum/Titanium) reduces heat and electricity costs for 24/7 operation. Single-rail designs provide clean, stable power to GPUs.

For deep learning, the most critical PSU specs—listed from most to least important—are:

  • Wattage: Must exceed total system power draw under full GPU load.
  • Efficiency Rating: 80+ Platinum/Titanium reduces heat and electricity costs.
  • Rail Design: Single +12V rail provides stable power for high-wattage GPUs.
  • Modular Cables: Clean cable management improves airflow and cooling.
  • Other specs like warranty and fan noise affect usability but are secondary.

The detailed specifications guide below explains each factor in depth to help you choose the right PSU for your specific AI workload requirements.
