That's a good point. I originally assumed you were using a known good reliable meter to get the measurements and the system was failing. If the system is running fine then I would not rely on any onboard software or hardware.I would never rely on motherboard sensors for voltage readings via software. Use a real voltmeter and measure the voltages at the video card add-on power plugs (PCIe) and the extra +12V plugs for the CPU (EPS/ATX/?? plugs).
