Last year, I purchased a 500W Rocketfish power supply from Bestbuy when I upgraded my graphics card. They had a very bad selection and I didn't want to purchase online. Ever since, I have had problems with my audio when I start to play games. After about 30 minutes into my game or 30 minutes into watching videos online after booting up, the audio starts to become filled with static and it gets worse over time. My internet even disconnected when I have a wired connection. However, when I restart my computer, the problem goes away entirely.
I have the same problem only with a Corsair AX850. I am definately not hitting even close to the max power consumption on it, but if my sound card is in any other PCI slot besides the top 1X slot it causes the audio to crackle, hiss, and whine. I moved the sound card down closer to the power supply and as i got closer, the crackling became louder. Is there any solution to this problem. The power supply i bought brand new so I don't see how it could be broken.
