Seasonic Power Supply SSR-550FM 550 Watts 80PLUS Intel ATX 12V 140mm Gold

FOCUS Gold
The FOCUS Gold power supplies are the ideal choice for people who do not want to break the bank, and yet seek the solid power supplies with great reliability and efficiency. The semi-modular cabling design provides the most basic connections while allowing flexibility on the peripherals. The high quality 120 mm Fluid Dynamic Bearing (FDB) fans are very quiet and proven to be very stable over the long run. The 120 mm FDB fan inside is regulated by the Seasonic S2FC fan control, which optimizes the fan speed according to the needs of the system.

80 PLUSGold
Seasonic was the forerunner of creating the very first 80 PLUS Gold certified power supply on the market and since that time it has built a very popular Gold series lineup that covers a full power range of power supplies with impeccable performance and efficiency.
The highly efficient 80 PLUS Gold certification guarantees greater than 87 %, 90 % and 87 % efficiency at 20 %, 50 % and 100 % operating loads, respectively. The clear advantage of buying a power supply with 80 PLUS Gold rating is the fact that the less energy gets wasted during power conversion, the lower the operating costs will be for the user.

Semi-Modular Cables
Some cables are permanently attached to the power supply (most of the time the 24-pin and the 8-pin ATX power cables) and the rest of the cables can be used to connect the rest of the available components.

S²FC – Smart and Silent Fan Control
The intelligent thermal circuit feature is designed to find the optimal balance between the necessity to cool the components and the need to run the power supply in the most silent manner possible.
