Seasonic has introduced its fourth iteration of Focus GX series power supplies with several new updates, including a new PCB layout and smaller MOSFETs. However, the main update Seasonic has incorporated is its all-new OptiSink technology, which has a revamped and improved cooling design.
Seasonic has coined the term OptiSink for its latest thermal solution for power supplies. OptiSink "increases internal space by approximately 48%, facilitating better air movement." According to the PSU maker, the extra space available allows OptiSink to exchange heat at a "significantly" faster rate, which boosts efficiency.
