[SOLVED] PSU voltage on ground pin NZXTC850

[Timetraveler12]

I recently bought an NZXT C850 to replace my NZXT Hale82 750(2012-2013). I haven't tested PSU's before but I checked the voltage output on the 24 pin for the C850 with a multimeter. All the voltages came in at tolerance except for the 18 ground pin (which showed 31 volts output). I went ahead and did the same on my old Hale82 and every voltage output came out fine, no voltages on any ground connections at all.

Is there a way to better identify whether the newer C850 can be used with the given output? Are there any other ways to test it before I install?

It might be a sense pin. All the ground pins on the mating motherboard connector are (most likely) interconnected. I would try to short it to the ground and see if the rest are normal... Prior to shorting it, the AC cord has to be out of the wall socket.
