The ElmorLabs PMD lets you measure the voltage, current and power flowing through your CPU and GPU power cables. An OLED screen attached to the board shows you the current power consumption including detailed values for each connector. The PCIE1, EPS1, EPS2 connectors can each handle up to 30 A of continuous current and PCIE2 (dual connectors) up to 50 A for a measurement capability of total of 1680W at 12V. Peak readings up to 60 A are possible on each channel. By connecting it to EVC2 (purchased separately) using the included cable you can view and log measurements on your PC at up to 10 ksps.
