This is a small PCB designed to allow for monitoring the power consumption of the +12V, +5V and +3.3V power rails from a standard ATX power supply. The design includes three INA195 chips which can be connected to external microcontroller ADC for data logging.

I can't take a look at the schematic, don't have Eagle. Do you really use those thin wires to carry current to the meters' current sensors, or are the current sensors themselves on the red PCB and the meters are modded to use the external sensors?
greetings and thanks for your question! I've added a PDF of the schematic for easy viewing. the current senors are on the PCB. The PCB is made with 2oz copper. The external displays in the picture are some off the shelf Voltage/Current Displays in which i removed the current sensing components and added connectors to interface to my design.
