SilverStone Technology has recently introduced its newest SFX power supply unit. Codenamed SST-ST30SF, it features 125x100x63.5 mm dimensions and weighs 800 g only.

The most uncommon feature ascribed to SST-ST30SF is that it can operate in passive mode if thermal conditions allow. The unit is equipped with a fan of 80 mm dimensional type; it starts rotating only when the surrounding temperature reaches 55 degrees. This promotes for a considerable power reduction and practically silent work when the fan gets disabled. An average noise level on active operation makes up 18 dB.
SilverStone furnishes the new entry with a single +12V rail, estimated for 22 A current. In its turn, +3.3V rail is estimated for 21 A current, while +5V rail – for 20 A current. It should be noted that this unit …
