SAMA Works on New Line of Entry-Level Energy-Efficient PSUs

Another day, another PSU maker jumping on the "green" bandwagon. Chinese company SAMA released pictures of its new line of entry-level energy-efficient PSUs, which are likely available in entry-level capacities (400~600W). The PSU relies on passive and active PFC mechanisms, with a power factor correction of 0.99, to contribute to its efficiency. While it is not 80 Plus rated, its makers guarantee at least 82% efficiency. The PSU utilizes a dual-forward switching topology, with high-efficiency PowerMOS instead of conventional transistors with half-bridge structure. Further, its main PCB is made of 2 oz copper layers. The PSU has fixed, sleeved cabling. It is cooled by a 120 mm load-controlled fan. Availability, and model information was not released.
