TAIPEI, Taiwan, April 28, 2026 — ASUS today announced the TUF Gaming Platinum series of power supplies, available in 850-watt, 1000-watt and 1200-watt versions. These PSUs feature a next-generation GaN MOSFET, military-grade durability, flagship fan design, and PCB protection for efficient and consistent power delivery. Compared to traditional silicon-based MOSFETs, the GaN variety delivers advanced energy efficiency, faster switching speeds, lower heat generation, and higher voltage resistance, positioning it as a server-grade material for demanding applications such as AI development, high-end gaming, and video editing. This MOSFET’s compact size also enables a streamlined layout with larger heatsinks and enhanced airflow for additional heat dissipation.

GaN MOSFETs for maximum efficiency and cooler operation​

Gallium Nitride MOSFET technology has been instrumental in making premium ROG Strix Platinum PSUs and ROG Thor III PSUs efficient powerhouses, so ASUS is excited to bring this tech to a range of TUF Gaming Platinum PSUs.

GaN transistors switch faster and conduct electricity more efficiently than silicon MOSFETs, reducing energy lost as heat. This improved performance can translate into up to 30% higher power efficiency, meaning more wall power reaches internal components instead of being wasted in the form of heat.

But efficiency is not the only benefit. A GaN MOSFET’s small size allows for a more organized internal layout, improving airflow and reducing the need for additional cooling components. This translates to cooler operation under heavy loads, which not only extends the lifespan of the PSU itself but allows for supremely quiet operation, helping users stay focused on the sounds they want to hear.

Low noise for quiet excellence​

TUF Gaming Platinum PSUs make acoustic performance a priority by maintaining sound levels below 30dB. This means a system can run intensive games or heavy workloads without the distraction of a loud power supply fan. Quiet operation enhances immersion, especially in competitive gaming or content creation environments where concentration matters.

Plus, the dual-ball fan bearings in the TUF Gaming Platinum PSU series last up to twice as long as standard sleeve bearings, ensuring the fan maintains consistent performance over years of use. This longevity keeps noise levels stable over the life of the PSU, preventing a gradual increase in fan noise that can occur with some designs. Together, low acoustic output and long-lasting fans make the TUF Gaming Platinum PSUs a reliable and unobtrusive foundation.

Built to last with military-grade durability​

TUF Gaming is known for durability, and the Platinum PSUs carry that tradition forward. These units feature military-grade Japanese capacitors, which provide long-term reliability and superior stability under high temperatures. This means users can trust their PSU to power intense workloads, overclocked CPUs, or multi-GPU setups without degradation over time.

A protective PCB coating adds another layer of defense, shielding the PSU against moisture, dust, and extreme temperatures. This reduces risk of failure in less-than-ideal environments, whether that is a hot and humid gaming room or a dusty workspace.

As Platinum PSUs, these units are also more efficient than many competitor options. They keep energy waste down, potentially shaving the cost of an electric bill. Less energy waste also means less unnecessary heat buildup, giving a PSU an easier life. Combined with premium components, this efficiency ensures long-lasting power delivery.

Built to last, each PSU comes with an 8-year warranty, offering peace of mind for those who demand long-term reliability.

Modern features for modern builds​

The TUF Gaming Platinum PSU series supports modern standards and cutting-edge hardware. These PSUs are ATX 3.1-compatible and include a 16-pin PCIe® cable capable of delivering up to 600W to PCIe 5.1 graphics cards. The cable’s high-conductivity copper pins maintain efficient current delivery and reduced heat buildup during high-power GPU workloads. This ensures that even the latest cards receive stable, high-capacity power, enabling gamers to push frame rates higher and content creators to handle intensive rendering workloads.

Fully-modular etched cables also help maintain a clean and organized build, improving airflow and making installation easier. These cables use tin-plated oxygen-free copper that is highly flexible and resilient, making it easy to route them cleanly and safely around tight corners during installation. They are also engineered for low resistance and minimal heat generation, operating up to 50°C below safety limits while meeting rigorous UL safety certifications.
