I might have to pick one of these up. A good PSU is essential for a good system; people tend to buy cheap and then are surprised when they’re loud, inefficient, and breaky. Well, here’s a little comparison of two of the newest silent PSUs on the block and it looks like (spoiler warning) the Silverstone Nightjar 450 is the pick of the litter. At 450 watts, it’s not going to run any Quadfire setups, but it is actually totally silent even under heavy load. The Fortron Zen 400 is more efficient at low load, but apparently makes a whining noise when stressed. They’re both a little pricier than, well, loud PSUs, but I know I was happy when I updgraded from the ol’ bargain-bin unit.
