Power supply units from Seasonic feature the OptiSink design, promising enhanced cooling efficiency with a claimed thermal conductivity boost of up to 8 times.
Seasonic, a leading manufacturer in power supply units (PSU), has introduced a groundbreaking technology, OptiSink, in its Focus GX series. This new innovation significantly improves thermal performance and efficiency compared to older implementations, offering quieter operation, extended component lifespan, and superior cooling solutions.
Key improvements in the OptiSink design include enhanced thermal dissipation, silent or fanless modes, compact form factor with effective cooling, and boosted efficiency with modern conversions.
Enhanced Thermal Dissipation
OptiSink's design ensures optimal heat removal at all times, allowing for more efficient cooling of the power supply components. This helps maintain lower temperatures under load without increasing noise levels, as demonstrated in various tests[1][2][3].
Silent and Fanless Operation
By improving heat management, OptiSink allows for silent or fanless modes where the cooling fan spins minimally or not at all in low-to-medium load conditions. This reduces noise while maintaining safe operating temperatures and extends the fan's life due to fewer rotations[2].
Compact Form Factor with Effective Cooling
The OptiSink technology is integrated into a compact 140mm deep design paired with a 135mm fan, which provides effective airflow and heat removal without requiring larger or more power-hungry cooling solutions[4][5].
Boosted Efficiency with Modern Conversions
Coupled with DC-to-DC converters and active Power Factor Correction (PFC), OptiSink improves not only thermal management but also power efficiency, allowing these units to achieve 80 PLUS Gold certification with up to around 90% efficiency[2][3].
Reduced Component Size and Revolutionised Installation
Seasonic's new design significantly reduces the size of many power supply components, including the heatsinks. The heatsinks in the new design can dissipate heat in any direction, offering improved cooling efficiency. Additionally, OptiSink changes how power supply components are installed, utilizing modern surface mounting technology with direct soldering of components[6].
Innovative Leap Forward
Seasonic's v4 (2024) Focus GX lineup is one of the first (if not the first) power supply lineups to use OptiSink technology, marking a significant leap forward in power supply efficiency and thermal performance. This innovation reflects a balanced design approach focusing on performance, silence, and durability[1][2][3].
The image above demonstrates the changes in the layout of Seasonic's GX Focus 2024 power supplies compared to the previous generation. OptiSink's implementation is purportedly being used in one of the first (if not the first) power supply lineups, setting a new standard for power supply technology.
