I agree it’s most likely not a problem with your PSU. I’m running a 5900X, 3080 FE and two NVMe drives on a Corsair Platinum SF600 PSU without any issues and no undervolts.
Let me guess, you’re using an Asus X570 or B550 mobo? I have the Asus Strix X570-I and the chipset is running 6000 rpm / 65 degrees idle, 8000-9000 rpm / 90 degrees under load. Tried replacing the thermal pad but that didn’t make a difference.
To be fair, Alex and team did refund me the shipping difference after I had sold my case to another forum member, so I have no doubt they will sort others out as well if applicable.
Yeah but they are if you’ve created them using the wrong tools, or even saved them in e.g. Notepad using the wrong encoding type (anything but Unicode).
