Commander Pro Voltage monitoring?


Recommended Posts

The PSU drops down the voltage from mains which is usually 110/120v or 220/240v, depending on where you live.


From there it steps down the voltage to the common supplied on different rails. Different components on your system is supplied by different voltages:


12v: Cooling Fans, CPU, GPUs, HDD

5v: Digital LEDs, USB Devices, some HDD and SSDs

3.3v: MCU on CoPro/LNP, some SSDs


Generally there is a lot of other components on the motherboard that required different voltages. The best way to tell is to look at what is supplied to each component:





To me it doesn't look good off hand, it could be a faulty sensor, or a bug. Generally the best way to tell is with a digital multi meter. I haven't used link, but I do use the new iCUE. I am guessing the voltage is being read by the CoPro is it has all 3 voltages supplied to it by the SATA connector. You might be able to find voltage readings elsewhere, like in the BIOS or with a HW monitoring tool. What PSU do you have?

Do you have the Commander Pro powered with a Molex to SATA adapter? That's the only time that I've seen that behavior.


If you do, power it with a straight SATA connector from the PSU.


Good point, Molex only supplies 5v and 12v. Sata Power supplies 5v, 12v, and 3.3v.

sorry, didnt have thread subscriptions on and thought no one replied.


@ solarity: this has nothing to do with the PSU. its the commander pro. It should only be getting the 12v from the SATA connector.


@ devbiker: it is directly connected with the PSU cable


and it seems other people have this issue as well as seen in other threads
