Just over a month ago Lee took a look at Silverstone's Fanless Nightjar PSU, giving it a Gold Award.  It has now arrived in [H]ard|OCP's torture chamber so you can see how well it works with a different system.  At the lowest load level of 25% of max the efficiency was a mere 89.79% but at 50%, 75% and 100% loads it stayed well above 90% and the temperature difference was 9C between the lowest load and the highest, impressive for a fanless PSU.  In the end not only was this the best fanless 500W PSU [H] has tested, it was the overall best 500W PSU they've seen, justifying the high asking price.

"What is more quiet than a computer power supply with a fan? You guessed it, a PSU with no fan. This unit has small footprint builds in mind featuring excellent Platinum efficiency, flexible flat cables, and of course no sound profile to speak of. Does the 520 watt rated SilverStone Nightjar hold up when we put it in the incubator?"
