I just purchased a Zalman PSU and it has very stable voltages, I'm not sure how well it handles high loads since I don't have a lot in my system right now. But the Zalman PSU's are sure quite. The only noise from my case right now is my CPU fan, and that will change soon.
<b>Just because I like AMD or Intel more at a time because of one product compared to another, does not make me a fan boy, it makes me a person who is able to make a decision for myself.</b>
