Seasonic at Computex 2025: 50 years of excellence and groundbreaking power supply innovations

On the occasion of its 50th anniversary, Seasonic presented an impressive range of new products at Computex 2025, underlining both technological advances and a clear commitment to quality and safety. Seasonic’s appearance at this year’s Computex was therefore more than just the presentation of new products – it was a reminiscence of half a century of technical expertise and entrepreneurial continuity. While many manufacturers have come and gone, Seasonic has developed into one of the most consistent and innovative players in the computer power supply sector since its foundation in 1975.

Anniversary and company history

Since its foundation in 1975, Seasonic has established itself as a leading manufacturer of power supply units. The 50th anniversary was celebrated at Computex 2025 with a specially designed booth highlighting the company’s development and milestones in power supply technology.

The history of Seasonic begins in Taiwan, at a time when computer power supplies were barely relevant in the consumer market. Early on, the company not only concentrated on industrial applications, but also ventured into the PC market in the late 1980s – long before the power supply unit was even recognized as a quality component in its own right. The fact that Seasonic later produced OEM solutions for well-known brands such as Antec, Corsair and XFX was no coincidence, but an expression of consistent manufacturing quality and development discipline.

The establishment of the company’s own retail portfolio in the early 2000s was particularly influential. The S12 series was Seasonic’s breakthrough with end customers, not least thanks to the consistent implementation of Active PFC, quiet fans and the use of high-quality Japanese capacitors. At a time when “80 PLUS” was not yet a common seal of quality, Seasonic was already one of the first manufacturers to systematically strive for energy efficiency.

Over the following years, Seasonic built up a reputation as an uncompromising technology driver with product ranges such as the X series and the later PRIME family. Soldering quality, voltage regulation, ripple behavior – Seasonic designs were considered the reference in almost all disciplines. However, this technical dominance has always been accompanied by a certain restraint in its public image. No marketing platitudes, no lurid packaging, just factual information and reliable technology.

New product lines and innovations

PRIME PX-3200: Performance for the highest demands

With the new flagship model PRIME PX-3200, Seasonic presented a power supply unit that offers an output of up to 3200 watts. This model is aimed at professional users and enthusiasts who place the highest demands on their systems. It has four 12V 2×6 connections and is fully ATX 3.1 compatible. The 80 PLUS Platinum certification guarantees high energy efficiency.

PRIME PX-2200: For powerful workstations

The PRIME PX-2200 was developed for high-performance workstations and AI systems. With an output of 2200 watts and two native 12V 2×6 connections, it offers sufficient reserves for demanding applications. The features include high-quality Japanese capacitors, fully modular cable management and a quiet 135 mm fan with Fluid Dynamic Bearing.

PRIME TX-1600 Noctua Edition: Cooperation for quiet operation

The PRIME TX-1600 Noctua Edition was created in collaboration with Noctua. This power supply combines Seasonic’s proven technology with Noctua’s expertise in quiet cooling. The result is a powerful power supply that enables virtually silent operation even under high loads.

FOCUS GX ATX 3.1 series: For the mainstream market

The updated FOCUS GX ATX 3.1 series is aimed at the mainstream market and offers outputs from 750 to 1000 watts. The power supply units are fully modular, 80 PLUS Gold-certified and have native 12V 2×6 connections. They are particularly suitable for systems with the latest RTX 50 series graphics cards.

12V 2×6 connections with integrated protection

A key topic was the introduction of the new 12V-2×6 connectors, which are a further development of the previous 12VHPWR connectors. These new connectors have integrated protection mechanisms that are realized by sensors and microcontrollers. These continuously monitor temperature and current and can initiate appropriate protective measures in the event of deviations. The aim is to ensure the safety and longevity of the connected components.

Conclusion

But it wasn’t just the technology that made the visit to the stand so special. It was the sovereignty with which Seasonic explained its products: no inflated performance promises, but well-founded technical information, comprehensible design decisions and a lived claim to long-term stability. It is worth mentioning that the topic of sustainability was not only touched on in passing. Durability, repairability and modular cable systems are not just functional advantages, but part of a philosophy that has proven itself over five decades.

The visit to Seasonic was therefore not only a journey through current products, but also through 50 years of computer history from the perspective of a company that has always seen the power supply as a crucial component – and has focused on it with technical depth, but also with remarkable modesty.

At Computex 2025, Seasonic impressively demonstrated how tradition and innovation can go hand in hand. With a focus on safety, efficiency and ease of use, the company is setting new standards in power supply technology and showing that even after 50 years, it is still one of the leading players in the industry.
