Power calculator

Power calculator,PSU calculator,PC power supply calculator online free
Voltage V:  V（volt）
Current I:  A（Ampere）
Power P:  W（Watt） 　

Formula:

Voltage V = R × I   (Formula 1)

Voltage V = P ÷ I   (Formula 2)

Power P = V × I   (Formula 3)

Current I = P ÷ V   (Formula 4)

Power P = V2 ÷ R (Formula 5)

power calculator tool precisely calculates the wattage needed based on your selected components, ensuring optimal performance and compatibility
