Seasonic 850W B12 BC Series atx virtalähde

The B12 BC Series is available in the standard ATX Form Factor and in wattages that are most common for a PC system. The Seasonic B12 BC achieves 80 PLUS® Bronze standard of providing at least 82 %, 85 % and 82 % power usage efficiency at 20 %, 50 % and 100 % operating loads, respectively. This efficiency, combined with Active Power Factor Correction, enables the B12 BC series power supplies to lessen energy waste, which translates into savings on the costs of energy costs for its users. In addition to being greatly efficient, the B12 BC units utilize the LLC resonant converter design, and the industry’s leading Smart and Silent Fan Control (S2FC).

80 PLUS BRONZE
The 80 PLUS Bronze certification indicates that a high percentage of the electricity is converted into useful power, therefore there is less heat lost and more money saved on the electricity bill.
The 80 PLUS Bronze certification guarantees greater than 82 %, 85 % and 82 % efficiency at 20 %, 50 % and 100 % operating loads, respectively. Sea Sonic’s B12 BC Series is an economical choice with great performance and high built-in value.
