Amd fx6300 overclocked to 4.3GHz, computer turns off in prime95.

To start with I would like to say that I am a complete beginner to overclocking and have just finished my first PC build this week. I am overclocking an AMD fx 6300.
I thought to look up overclocking tutorials and found one here. I followed the instructions and the computer boots up fine but when I open Prime95 the computer shuts down within 5 seconds of starting the torture test. I have tried to do a bit of research and have had various conclusions such as overheating and a poor PSU. I am thinking that it is unlikely that it can be overheating because during these 5 seconds the temperature only reaches 60 celcius. My PSU is the most likely culprit in my eyes and I am now regretting cutting costs, it is this one. If anyone could help me try and figure out this problem then i would be very grateful.

  1. What model is your PSU? if the system is shutting down without even displaying a BSOD, it's most likely a power issue. High temps spiking could also shut down the system depending on the threshold set.
  2. Hi thank you for the response.The PSU is an alpine 700w. I am not even getting BSOD just instantly turns off. Could there be high temperatures within 5 seconds of even opening the program?

    I am not sure of how stable is that PSU, but with 700 watts you should be able to power the components in your build just fine, people used to overclock stuff before 80+ certification was out. Yes, if you are using stock cooler there is a high chance the chip reached the maximum safe temps in a spike, AMD runs hot, so for overclocking you need a good aftermarket cooler.
  4. Thank you for the help, I think I will buy a new cooler after your advice then I will try the overclock then.
