A new line of inexpensive power supplies, with which the famous Taiwanese manufacturer has opened its doors to the market of affordable power supplies. Seasonic believes that the B12 BC series power supply will become a reliable basis for a mid-level gaming, multimedia or desktop PC with a simple fixed cable system. Despite the positioning, the B12 BC power supplies are equipped with an input filter, an APFC module, DC-DC converters, Chinese high-temperature capacitors at all key nodes and an efficient LLC topology.


Thanks to this, the B12 BC models provide efficiency in the region of 89% (confirmed by the 80+ Bronze certificate) with very small voltage deviations, low ripple level and excellent power reserve. In tests, many models of this series produced almost 100% of the nominal value on the main power line, and also successfully withstood overload (up to 26%). Of course, there were some savings, but they should be compensated by an official 5-year warranty from the manufacturer.

At the time of writing this material, Seasonic has announced only one new product — Seasonic B12-BC with power variations of 450, 550, 650 and 750 watts. The former will successfully fit into a relatively simple system with an inexpensive graphics card, the latter will be able to power the configuration with a pair of powerful video cards without any problems and at the same time will not disturb the rest of the owner. After all, the proprietary Seasonic Smart & Silent Fan Control intelligent cooling system is also used here, which we have seen more than once in Seasonic Prime and Focus power supplies.
