Possible Power Supply Failure, Need Help!

[Btobalskii]

After testing multiple components of my computer and replacing some my computer still was not working. It seemed as if it wasn't getting enough power to stay constant. I finally thought to test the power supply and found how to test it with my multimeter. Below are the results of the test. Please look at pin 14 and let me know what you think. According to the min/max range it's okay but it's very borderline.
Pin/supposed voltage/my voltage
1/3.3v/3.35v
2/3.3v/3.35v
3/ground/0
4/5v/5.09v
5/ground/0
6/5v/5.09v
7/ground/0
8/pwr_on/5.09v
9/5vsb/5.14v
10/12v1/11.97v
11/12v1/11.98v
12/3.3v/3.35v
13/3.3v/3.35v
14/-12v/-10.88v
15/ground/0
16/ps_on#/0
17/ground/0
18/ground/0
19/ground/0
20/nc/not present
21/5v/5.09
22/5v/5.09

It does seem off. As far as I know, it should be between 11.5-12.5v
