Seasonic S12 III SSR-550GB3

Keep up with the times

SeaSonic S12III-550 is an inexpensive power supply with quite modern specifications. Voltage stabilization on low-voltage lines — progressive separate DC-DC. SeaSonic was the first among PSU manufacturers to completely abandon obsolete group stabilization.

Strict control

In addition, all SeaSonic power supplies, without exception, pass external independent certification of energy efficiency 80 PLUS. So, the SeaSonic S12III-550 model has earned a "bronze medal", which implies an efficiency of 85 percent. Moreover, this is far from the lowest award — lower in the hierarchy is 80 PLUS White with an efficiency of 80%.

Beautiful wiring

The cables of the SeaSonic S12III-550 are non-removable, but flat and pliable, which contributes to neat cable management. In addition, the non-modular design makes this PSU very compact by ATX standards — only 14 cm in length. It will certainly fit into any, even old or low-cost PC case without any problems.

Extra power

The SeaSonic S12III-550 delivers 546 watts on the main +12V line, that is, the total power on all lines (+5V and 3.3V) is even higher than stated. To put it simply, a 550W SeaSonic meets the 600-650W PSU requirements of other brands. The savings, perhaps, only affected the fan — it is quiet, but on a conventional plain bearing. However, a five-year warranty allows you not to worry even about this.
