Silverstone SST-ET550-B v1.2 ATX power supply 80 PLUS bronze - 550 watts [SST-ET550-B v1.2]

Therefore, if necessary, today's crucial +12 volt line can be loaded with almost the entire nominal power - ideal for fast graphics cards and modern processors in powerful PCs. The + 3.3 and + 5 volt rails together can deliver 110 watts - enough for a whole battery of HDDs. In addition, there is the whisper-quiet 120 mm fan with a gentle and precise rotation curve and the optimized airflow, which make the power supply one of the quietest of its kind.

> The Silverstone SST-ET550-B: Full power with high efficiency The 550-watt model has more than enough connections and power for gaming computers. The electronics deliver up to 504 watts and 42 amps on the +12 volt line, while the +3.3 and +5 volt rails provide 110 watts and 20 amps. The particularly high level of efficiency meets the requirements of 80 Plus Bronze 230V EU and thus exceeds 82/85 percent at 20/100 percent load (at 230 V input voltage). The highly efficient circuit design has independent DC-to-DC converters for the 3.3 and 5 volt outputs, which ensures extremely precise voltage regulation.
