Commands

Values enclosed in <...> means they are optional

Read Bytes of each command starts with [<REPORT_ID>, FIRST_WRITE_BYTE, SECOND_WRITE_BYTE] but are skipped to improve readability. REPORT_ID is always 0x00 and is optional depending on the hid library

Write Bytes of each command have to begin with the REPORT_ID (0x00) but it’s skipped to improve readability. Might be optional depending on the hid library

Serial Number [0x31, 0x3f] Null terminated ascii string with PSU serial number

Value calculation pseudocode:

value = VALUE_H << 8 | VALUE_L;
exponent = (value & 0x7800) >> 11;
sign = (value & 0x8000) >> 15;
fraction = (value & 0x7ff);

if (sign == 1)
    exponent -= 16

result = Math.Pow(2.0, exponent) * fraction

WATTS = VVOut12 * VIOut12 + VVOut5 * VIOut5 + VVOut33 * VIOut33

EFFICIENCY = efficiency_lut[(int)(WATTS / 10.0)]

efficiency_lut is different for each psu model, exact lut values are currently unknown
