Bestec ATX-300-12E, this power supply is so loud!!!! What would be a suitable MUCH quieter power supply??
Mother board: Asus M5A99FX PRO R2.0
CPU: AMD FX-6300 6core
Graphics: NVIDIA GeForce GT640
Running 2 hard drives.
Only have CPU fan and the graphics card fan.

Also, got this used, seems like a solid set up for video editing and such, it's no top of the line stuff I'm sure but it's does run Vegas 14 smoothly, esk.
