Seasonic Launches New FOCUS GX (2024) PSU Series With OptiSink Design
Having received much positive feedback from partners and visitors during its first announcement at Computex 2024, Sea Sonic is proud to launch the new Seasonic FOCUS GX (2024) Series. In the footsteps of the popular FOCUS Series power supplies, this new iteration introduces innovative features that aspire to follow the legacy and position the FOCUS GX (2024) at the new Center of Attention.
Introducing a Technological Milestone: OptiSink
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.
Transitioning from Traditional to New Technology
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.
Key Thermal Design Innovation
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 aluminium heat sinks.

I can imagine its difficult to innovate in this space but man... who the hell cares about this?
Relying on thermal pads or globs of extremely viscous zinc oxide grease to transfer heat away from the plastic outer casing of a MOSFET always seemed like a dumb way to do things when the bulk of the heat from these things is transferred to the PCB anyway. Cool the PCB better and you won't need half a kilo of heatsink that's barely connected to the heat-generating components in the first place.
If you cared about buying good and reliable hardware, you didn't need OptiSink and you never will.
Its called marketing. And buying into that is really just being gullible. It takes just a bit of logic to figure that out. The PSUs already did fine and were awarded 10 year warranty without this change. Its not rocket science.
Now, if Seasonic was willing to extend that warranty to say 12 years because 'now they have OptiSink', then we're talking about something substantial. They're not. Ergo, its a bullshit story.
Its far more likely they just managed to find a way to use fewer materials to achieve similar results. So yeah, that's better. But it doesn't affect you in any way, despite the fact Seasonic tries to play make believe that it does. If it did, again, they'd have extended their warranty or something other to underline it.

first review is in
The new Seasonic Focus V4 line uses an interesting PCB design, allowing for lots of room between components, so airflow can be high without pushing the fan speed. Nevertheless, the PSU’s average noise output is not among the lowest in this Wattage category. The same goes for its average efficiency and overall performance. It seems that the new design didn’t help in improving the overall performance, with the previous GX-1000 model scoring a bit higher than the new model. The low starting voltage level of the 12V rail affecting its load regulation, the average power factor readings, the sky-high inrush currents, the increased vampire power at 230V, and the high voltage drops at 12V in the ATX v3.1 transient response tests are the main culprits behind the unit’s low overall performance. At least, ripple suppression is good.
