"The NightJar Fanless PSU series is available in two flavors, 300W and 450W. I’ll be reviewing the Nightjar 450W Zero dBA Fanless Power Supply (SST-ST45NF) which peaks at 500W and this is more than enough power for a HTPC or a silent gaming build. This PSU uses solid state Capacitors which results in cleaner more reliable power than cheap capacitors found in many other PSUs on the market. The housing is made from thick aluminum and it acts as a heastink since this PSU does have a fan to keep it cool. It also has plenty of ventilation holes, but it's crucial to have excellent case ventilation to insure this PSU gets adequate cooling. Watch the video to find out more." ~3dGameMan.com
