Is 9.6V normal for an ATX supply? My computer sometimes shuts off while I am using it. I used a fan speed program that monitors the voltages. The only voltage that is significantly different than the supply specs is the 12V output.

I suspect the 9.6v reading you are getting is the +12v rail reading?
If so that is your issue because it should not be below 11.74 volts to be stable. Anything less can be a potential issue. Since yours is showing 9.6 I would be suspicious of a failing PSU.
What program are you using to check this with?
Just to verify can you do the following and post the requested screenshots please.

Download Speedfan (The download link is to the right), and install it. Once it's installed, run the program and post here the information it shows.
The information I want you to post is the stuff that is circled in the example picture I have attached.
To make sure we are getting all the correct information it would help us if you were to attach a screenshot like the one below of your Speedfan results.

To do a screenshot please have click on your Print Screen on your keyboard.
  • It is normally the key above your number pad between the F12 key and the Scroll Lock key
  • Now go to Start and then to All Programs
  • Scroll to Accessories and then click on Paint
  • In the Empty White Area click and hold the CTRL key and then click the V
  • Go to the File option at the top and click on Save as
  • Save as file type JPEG and save it to your Desktop
  • Attach it to your next reply

Please download and run Hardware Monitor
Installation (setup version only)
HWMonitor is a hardware monitoring program that reads PC systems main health sensors : voltages, temperatures, fans speed.
The program handles the most common sensor chips, like ITE® IT87 series, most Winbond® ICs, and others. In addition, it can read modern CPUs on-die core thermal sensors, as well has hard drives temperature via S.M.A.R.T, and video card GPU temperature. Please get a screenshot of the sensors window and post it in your next reply.

Thanks, I will get back with the results shortly. This is a computer that has been down for a couple of years and I just installed a new mother board. Trying to get it back up and fully functional.

Yep I would say the issue is with the +12 volt rail and not being within the accepted range for powering the system.
Do you know the make and model of the PSU?

Just took the PSU apart. Looks like it is almost toast. I can see it has been pretty hot and a couple of bad solder joints.

Thanks for helping putting the finger on it.

Yeah I would suggest a new one and you might look at a name brand that is 80 plus certified.
