All the power supplies you listed are complete garbage. None of them even have a basic 80+ rating for efficiency and probably have no power protections either. They also probably only have a 1yr warranty. A good 80+ psu will have at least a 3yr warranty.
Yes a good 350 like antec is better than a cheap 500.
I recommend a Antec 350/380 or Corsair 430, or something at least 80+ rated.
i dont play games and my video card is fanless, my pc is rigged to a plasma in the bedroom we use for watching movies etc.. and ideally leave on overnight to download but if its noisy then not ideal hense looking for as quiet as possible
