600W Seasonic PRIME 600 Titanium Fanless

RRP: $190 / street price: $250

Most ‘fanless’ power supplies are in fact not truly fanless; they merely have a zero-RPM option available, usually via a physical switch on the back of the unit that manually deactivates the fan. Seasonic’s PRIME 600 Titanium Fanless lives up to its name, though, with no fan and a perforated casing that allows built-up heat to more easily dissipate. seasonic.com
