Voltages jumping around (12V, 5V, 3.3V) (Corsair HX850i)


Recommended Posts

Hello eveyrone,


about a month ago I built myself a new desktop PC.


Gigabyte GA-X99M Gaming 5

Intel i7 5930K

Corsair Vengeance LPX (4x4gb)

Gigabyte GTX 980 Ti

Corsair HX850i (Internal USB-port is connected)


However, since a few days i noticed my 12V, 5V, and 3.3V values jumping around randomly. (Sometimes it shows the correct values, last screenshot)

Usually all sensors show 12V, but as you can see in the screenshots it can go pretty much anywhere.

I've tried installing HZMonitor, but the values I get from here are even more concerning.

Since these values are static, and not correct at all.


Even though none of these voltages seem correct, my system is running just fine.

But I can't figure out if i'm dealing with faulty sensors, a faulty PSU, or perhaps something else that went wrong.

So I hoped the experts on these forums can help me. (I've added the sensordebug info)

I suppose the issue may be because your PSU provides erratic readings for voltages. It doesn't cause an actual problem though. If suddenly the +3.3V rail would provide 12 Volts or the +12V rail would provide 5 Volts, your system would immediately lock up :)

And those erratic readings may just be caused by a collision between AIDA64 and another software polling your PSU. Do you have any other software installed that may poll the PSU?

Thank you for the quick reply,


I've already found it hard to believe that these were actual values since I wasn't experiencing stability issues.

I've got Corsair Link installed (for the cooling and PSU), so this might be interfering with both Aida64 and HWmonitor.


And because it's only these 3 values which seem incorrect, I think i'll just trust my PSU is working like it should
