The below screenshot shows the differences in voltage readings using CPUID Hardware Monitor v1.15 and HWiNFO32 v3.50-715. I have also tried Everest Ultimate Edition v5.50.2100 and it reflects readings that are similar to CPUID Hardware Monitor. I have also tried HWM BlackBox 2.0 and it reflects readings similar to HWiNFO32. I tested my power supply using a voltage meter and it showed the 12v output to be 12.22v. It is puzzling to see different programs showing different values for the voltages. Not sure which program has accurate readings.
