More about whys power supply make sound gaming
  1. It's called coil whine and it happens when more power is running through the system, normal and annoying, usually happens as parts age
  2. or from overclocking
  3. ok so would buying an 80+ rated Power Supply help at all ? I was about to get the XFX 650 watt 80+

    yes, another thing that helps is giving yourself a little more power overhead. the less stressed a power supply is, the less chance of coil whine. but a new psu would definately help
    sources of coil whine
    1.gpu, either under load or after lots of overclocking and age
    2. motherboard (luck of draw but very common) - next step if replacing psu does not work, as it would mean you were wrong about the initial source of the coil whine
    3. power supply under load, or showing signs of aging.
  5. My system is overclocked I have a phenom II X6 clocked from 2.70 to 3.40 but the coil wine didn't start until installing my GTX 660 so I feel like it'stime to just buy an 80+ rated PSU then
  6. oh it's the Power Supply alright because I pulled it out of the case put my ear up to it and that is where the sound is coming from also in the recording the mic was right up to the PSU while it was pulled away from the case
