Just got this new Corsair AX650 PSU. Looking at HW Monitor Version 1.19 and its showing about 7.08V on what looks to be like my 12V rail, not sure if this is accurate, supposed to be like this, or if this is even a measurement. Perhaps the voltage changes?
In another thread someone else was reporting:
"+12V is only about 7.9V, and +5V reads as 3.9V. Readings were taken using CPUID HWMonitor and Pirifom Speccy; both give the same values. In BIOS though, the voltage readings appear correct."
Testing further with a multi-meter the same person reported:
"Quick voltage check done while running 3DMark2006. I used an unconnected Molex connector and tested DC volts from ground to the yellow wire while the system was under load. 12V readings are steady between 12.2 and 12.15."
HWMonitor and similar programs rely on digital codes for things like voltage and temp readings.
And the database of codes doesn't always match up, especially on newer hardware.
So it's always good practice to double check what the systems own health monitoring system is reporting.
