In this review PCSTATS is testing out an entirely fanless, silent 460W power supply from Seasonic's modular "X" series. There aren't very many fanless power supplies on the market so this is a bit of a treat. If you're planning on building 100% silent computer system the Seasonic X-460 Fanless is certainly tempting; it features a 460 Watt power level, modular cable system, matt black fingerprint resistant steel case, good EMI shielding and is able to sustain a peak load of 38A on the +12V rail.
