B12 BM Series
The B12 BM Series is available in the standard ATX Form Factor and in wattages that are most common for a PC system. The Seasonic B12 BM 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 BM 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 BM units utilize the LLC resonant converter design, and the industry’s leading Smart and Silent Fan Control (S2FC).
