The FOCUS GX (2024) Series, an update to Seasonic’s FOCUS series of power supplies that ushers in compliance with the ATX 3.1 and PCIe 5.1 standards alongside several new features, including OptiSink for what the company says is increased internal space of up to 48%, enabling better air movement, is now available in China but coming to North America and Europe in October 2024 and mid-November 2024, respectively, Seasonic has announced. The new PSUs, which are available in power capacities of up to 1,000 watts, also advertise a key thermal design innovation, whereby the MOS (metal-oxide semiconductor) is directly soldered onto the copper surface of the PCB (Printed Circuit Board) rather than mounted using screws and thermal pads.

Seasonic on its new power supply:
The FOCUS GX (2024) was redesigned with a brand new PCB layout and is produced during a new manufacturing process involving automated surface mount technology. Improved design also includes the use of smaller MOSFETs and heat sink components, which increases the internal space within the PSU to promote better airflow. All these enhancements not only improve the overall quality of the FOCUS GX (2024) Series, but also make it more efficient and more reliability in the long run.
Compared to traditional thermal solutions, this upgraded layout, termed OptiSink, increases internal space by approximately 48 %, facilitating better air movement. At full load, the power supply fan can exchange heat at a significantly faster rate due to the larger space available, resulting in improved overall efficiency, and promoting an environmentally friendly operation.
During manufacturing, the MOS (Metal-Oxide Semiconductor) is directly soldered onto the copper surface of the PCB (Printed Circuit Board), in order to harness the superior thermal conductivity of copper. This approach contrasts sharply with the older method of using screws and thermal pads to mount the MOS onto aluminum heat sinks.
