cars10 Posted August 7, 2018 Share Posted August 7, 2018 I kinda just noticed there is a voltage area in my Link software under the CoPro, and the 3.3v readout is very werid, see here: https://imgur.com/a/E8F2Q1K What voltages are these from/for? Why is my 3.3v off, and is that bad? Thanks for any help! Link to comment Share on other sites More sharing options...
solarity Posted August 9, 2018 Share Posted August 9, 2018 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: https://www.moddiy.com/product_images/uploaded_images/corsair-ax1200i-psu-modular-cables-pinout.jpeg 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? Link to comment Share on other sites More sharing options...
DevBiker Posted August 9, 2018 Share Posted August 9, 2018 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. Link to comment Share on other sites More sharing options...

cars10 Posted January 9, 2019 Author Share Posted January 9, 2019 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 Link to comment Share on other sites More sharing options...
