As title 
This is for a basic system (dual-core, 1 GPU, 1 HDD, 1 Optical, no add-ins) that I'm being noise-conscious with so needs to be as quiet as possible. Would also prefer one that supports both 20-pin and 24-pin ATX connections, but nothing too OTT and expensive. Are Be Quiet! worth considering for a brand? since their PSUs look pretty competitively priced.
