Is there a way to measure the electric current or power of the whole computer or its components using software? Voltage can be measured, and I am wondering why not with the current/power.

  • @AlexChamberlain Standard IBM or Intel compatible computer. – sawa Jun 12 '12 at 7:06

    The only way to do this is with additional hardware. If you're lucky, you might be able to find a power supply with a current feedback. – Alex Chamberlain Jun 12 '12 at 7:40

Voltage can only be measured because most modern machines have hardware built-in that can do so; the software simply talks to the hardware over e.g. I2C and reads the values from it. No equivalent hardware for measuring current is in modern computers.
