The eXtreme Power Supply Calculator v2.5 features a long anticipated Amperage calculation per +12V, +5V and +3.3V rails as well as an improved calculation engine, the latest CPUs, video cards, and other components from Intel, AMD, NVIDIA and more.
“I've seen a few to date, but this one is simply impressive in the breadth and level
of details covered,” commented Robert Tanner (Kougar), Bjorn3D Staff member. “Besides overclocking,
you can factor in Peak Utilization, Capacitor Aging (Explained at the end of the page),
and Surge Compensation which deals with the power surge required when you first power on
the system from a cold start. From my experience trying to calculate what my main rig draws,
the number given was very accurate.”
