It’s official! Sea Sonic, the company behind the Seasonic brand is now eligible to apply for an AARP membership due to hitting its 50th anniversary since being founded in 1975. Not only will they be able to get 10% off their hair cuts from here on out, they’re also bringing innovations in the technology behind power supplies.
Optisink 2.0
One of the key themes is finding ways to make power supplies smaller, more efficient and more reliable. At Computex 2024, we were introduced to Seasonic’s Optisink technology which moved the heatsink from the mofsets and other power components to live directly on the PCB allowing for significant space and weight savings while still maintaining efficient cooling.
For this year, they are making the Optisink better by a factor of one, which yields Optisink 2.0. It improves upon the original by adding heatsinks to the top of the mosfets and having an injection spot for thermal grease to improve heat transfer away from the mosfets.
The Most Powerful PSU at Computex 2025
We saw a number of power supplies offered up at Seasonic competitors that provided an even 3,000 watts of power. Not to be out done, Seasonic was showing off a power supply that can sustain 3,200 watts of power in the form of its PRIME PX-3200 (Ed: That seems about twice as powerful as the PX-1600 that we did a review on a while back). It was sporting a full 6 12HVPWR plugs on its backside to power whatever frankensteined GPU rig your heart desires to build. Keep in mind that it requires a 40 amp 220V circuit to properly run.
Optiguard
Another technology that Seasonic is working on is called Optiguard. The goal here is to provide real time monitoring of the 12HVPWR connector and shut down the power supply if one or more of the cables gets loaded with power that is beyond its specifications. While the GPU on the other end is supposed to be doing the needful to prevent itself from going out in a glorious puff of the magic smoke, Optiguard will be there to do the actual needful before that happens.
In time, Seasonic plans on feeding this information back into your system and do the fancy overlay graph so you can see what is going on with your power supply at any given time.
Rotating Power Supplies
Seasonic has another concept that it is working on with its CORE line. As it has been working to shrink its power supplies, you can see they’ve cut a few inches off of this one. In its standard form, it will mount to your typical ATX case and work just as expected. The main difference here is that there’s also an add on box that squares up the unit and provides a channel to run the wiring through, allowing you to rotate your PSU by 90 or negative 90 degrees to work with cases that require power supplies that defy space-time continuum.
Seasonic and Noctua Collab
Last year we saw the introduction of the Seasonic Prime TX-1600 Noctua Edition, and for this year, Seasonic is expanding on that with the Seasonic Prime PX-1200 Noctua Edition. It sports a smaller form factor than the original, and given that it’s an 80 Plus Platinum grade supply with a lower wattage, the pricing might be a bit more appealing once it hits retail shelves.
Max Flow Fans
Seasonic is also introducing its MAX Flow fans that are aimed at the high end of performance with high static pressure (8.5 mmH20) and airflow (154.85 CFM) running around 3300 RPM. They are thicker than usual at 30mm and will come in black and white flavors. The fans have a built in switch that let you adjust performance between a Silent, Hybrid and Performance mode.
