The Seasonic SS-350TGM is probably the best quality low noise TFX power supply currently available in the market. A number of innovations mean this PSU can operate silently with the fan stationary when the attached system load is less than 50%, under most conditions. Furthermore the modular cabling approach means system integrators can develop a range of custom cable solutions with just a single PSU, flexibility that reduces and simplifies stock holding.
