Power Supply Unit
Modern GPUs like NVIDIA’s RTX 40 and RTX 50 series are constantly testing the limits of the power supply that powers them by periodically demanding short but very large bursts of power. These transient power spikes, also called power excursions, are one of the main reasons why choosing a power supply that is compliant with the ATX 3.1 standard has become increasingly important.

Choosing between an ATX and an SFX power supply is not just about looks. It will determine whether your build stays cool and quiet or becomes cramped, hot, and noisy. PSU size influences airflow, fan noise, cable routing, and in tight builds, can even affect power stability under real gaming loads.

While the quality of a power supply may not directly affect in-game frame rates, it plays a critical role in overall system stability and component longevity. For most users, selecting a PSU based on wattage, efficiency rating, and ATX standard compliance is sufficient. However, for high-end systems, it can also be useful to understand the difference between digital and analog power supplies.

A power supply will rarely be the flashiest component in your PC. It often sits out of sight in your PC, quietly powering every component. Without the right power supply, your PC can become unstable, shut down unexpectedly or even suffer hardware damage.
