Bad PSU?

I bought a Corsair TX 750 5 months ago, lately I have been getting freezing in games. I had both my CPU and GPU overclocked, so I decided to reset my GPU overclock.
I got a freeze on the desktop.
I am thinking it is maybe my PSU...

Speedfan says I am getting 10.56V on the +12V rail.

Is that bad for idle? :o

  1. did the system freezed after you overclocked?

    I play an mmo, lord of the rings online... fine.

    Any other game, like Skyrim or Saints Row the third, it freezes after a while.

    So I reset the overclock on the card, and a few hours later my system froze on desktop...

    That is bad no matter what you're doing...if Speedfan is properly receiving the voltage readings from the mobo. The ATX specification allows +-5% voltages on any of the rails. The acceptable voltage range on the 12V rail is 11.4-12.6V; your reading of 10.56 is 15 out of spec and would certainly cause instability issues. That may not be your issue...Speedfan does not support every mobo in existence and you could be getting incorrect voltage readings from Speedfan.

    try resetting both the cpu and the gpu to the stock clock speeds and see if the problem gets solved,also check if all the power connectors to the gpu are properly inserted.
  5. Doesnt sound like a PSU problem. Its either CPU or GPU. Try putting everything back to stock speeds.
  6. Alright, I will reset everything.

    Is there another program I can monitor the voltage with?
  7. Voltage still stayed the same...
  8. Got this today: Display driver stopped responding and has recovered
  9. Have you checked the PC Health Status Voltages in the EFI BIOS?

    Health status? no, I will do that now.
  11. Display drivers crashing is related to the graphic card drivers. You might want to put everything back into stock speeds then clean out the drivers and install them again.

    Sidenote - speedfan doesn't always put out the correct readings...
  12. Well, I haven't had any crashes since running the card at stock...

    Just driver crashes.

    So maybe you are correct.

    I will try it, I will also buy a voltmeter to check out the 12v rail on my PSU
  13. i highly doubt it's the PSU since it's a well known and well loved / reputable PSU.

    Display driver crashes are nearly 99% of the time due to the nvidia drivers being corrupted or bad.

    Also don't buy a voltmeter until you rule out the possibility of just driver problems as it'll be a big waste of money if you get it then find it its just a software issue.
  14. Okay.

    But it's ATI, not Nvidia.
  15. Oh.. my point still stands HAHAHA
    my bad.

    Yah... ati doesn't have the best records when it comes to video card drivers.... lol
  16. So everyone keeps telling me. -_- lmao
  17. Software is notoriously bad at getting totally accurate voltage readings, check your voltages in BIOS or with a digital multimeter if you want accurate numbers, but I can tell you that speed fan is wrong since your system would not be able to keep running once the 12 V rail dropped below 11 the under voltage protection would kick in and turn it off.

    A recent version of HW monitor finally fixed the voltage readings on my board, but several versions used to read my 12 V rail as somewhere between 4 and 8 Volts which was obviously wrong.

    The crashes are most likely software related.
