The fact that computers must operate in close proximity to people means that any sound they produce is bothersome and extraneous. As quiet computing has grown from a hobby of a few people to a major part of the industry, the number and quality of the available quiet/silent parts has increased greatly. This review will be taking a look at Antec's new Phantom 500 power supply unit. Its predecessor, the Phantom 350, has been a huge hit for Antec and has become the benchmark for fanless power supplies. The Phantom 500 has been bumped up from 350W to 500W and also has a number of other interesting changes, the most important of which is the addition of a fan. This means this power supply is no longer fanless but is Antec has still labeled it as silent.
