red-ray Posted September 29, 2014 Share Posted September 29, 2014 Ever since I got my AX1500i I noted that Corsair Link reported all the PCIe currents as zero almost all the time. I assumed this is down to my GPUs not using any power from the PCIe supply, however recently I figured out how to read the values programmatically, so wrote some code to read them every 2 seconds and record the Average (of none zero), Maximum, Minimum and the number of times a none zero value was read (Samples). I then ran the code for about 9 hours and got: Item Name Current Average Minimum Maximum Samples AX1500i Supply V 242.500 241.443 231.500 245.000 33,066 AX1500i +3.3 V 3.313 3.313 3.297 3.328 ...

AX1500i PCIe A A 0.000 - 4.500 4.500 1 I was surprised no currents less that 4.500 Amps were recorded and I wondering why. I assume this is down to what the PWMs report and would like to which PWMs the AX1500i uses. I checked in http://www.corsair.com/~/media/Corsair/download-files/manuals/psu/AX1500i_Manual.pdf and that does not help. Can anyone tell me the PWM part number please as I expect taking the PSU apart would invalidate my warranty. Link to comment Share on other sites More sharing options...
SpDFrek Posted October 3, 2014 Share Posted October 3, 2014 The cutoff for the software to display information on any current is 3 amps, below that it just displays zero. Link to comment Share on other sites More sharing options...

Thank you for the reply, but my code will display currents below 3 amps were the hardware to report < 3 amps. It seems the hardware never reports currents < 4.5 amps though.
