PC Power Supply & FPS Calculation Guide

How does Wattbench calculate recommended PSU wattage?

We aggregate the peak boost power draw (PL2/MTP for Intel, PPT for AMD) of your processor, graphics card transients, motherboard rails, RAM kits, and cooling pumps, incorporating a safe headroom buffer with ATX 3.1 transient excursion standards.

Why do GPU transient spikes matter?

Modern high-end graphics cards can draw double their rated power for micro-seconds during intensive gaming scenes. Our ATX 3.1 guard ensures your power supply unit can handle these rapid spikes without tripping system protections.

How accurate are the real-time gaming FPS projections?

Our matrix scales performance based on relative architectural tier matching between your selected CPU and GPU, benchmarking typical frame rates at 1440p High/Ultra settings across titles like Cyberpunk 2077, Warzone, and Valorant.

How often is hardware data updated?

Our component database is audited and updated bi-monthly to include newly released desktop components, mobile chipsets, and modern power supply revisions.
