550W 80 Plus Gold Power Supply

Exceptional Power for Mainstream Gaming Builds:

The ASUS ROG Strix 550W Gold Power Supply delivers the perfect balance of power, performance, and efficiency for modern gaming systems. Designed to bring high-end ROG engineering to mainstream rigs, this PSU combines innovative cooling technologies with superior build quality. It ensures stable, efficient power delivery while keeping noise levels impressively low — making it an ideal choice for gamers, creators, and performance enthusiasts seeking a reliable foundation for their systems.

Frozen Silence The Perfect Balance of Power and Quiet Operation:

The ROG Strix 550W Gold is part of the Frozen Silence design philosophy, blending premium components with advanced cooling to deliver exceptional performance and near-silent operation. Drawing inspiration from the powerful ROG Thor series, it uses massive ROG heatsinks and the Axial-tech fan design found in high-end NVIDIA RTX™ graphics cards. Combined with low RDS (on) MOSFETs and Japanese capacitors, this PSU provides rock-solid stability, efficiency, and quietness — even during the most demanding gaming sessions.

ROG Heatsinks for Enhanced Cooling and Durability:

The integrated ROG heatsinks inside the Strix 550W are twice the size of conventional designs, offering superior thermal management. This increased surface area helps dissipate heat more effectively, resulting in lower internal temperatures and longer component lifespan. Thanks to this advanced cooling, the PSU can maintain 0dB operation for extended periods, ensuring whisper-quiet performance even under load. The efficiency of these heatsinks makes them one of the defining features of the ROG Strix PSU series.

Axial Tech Fan Design Engineered for Efficiency:

Borrowed from the top-tier ROG graphics card lineup, the Axial-tech fan design features a smaller fan hub that allows for longer blades and a barrier ring that directs airflow downward with greater precision. The 135mm fan ensures optimal cooling with minimal noise by maintaining lower RPMs during operation. This design keeps the PSU running cool while minimizing power consumption, making it one of the most efficient fan systems in its class.

Dual Ball Bearings for Extended Reliability:

To ensure long-lasting performance, the ROG Strix 550W Gold utilizes dual ball fan bearings known for their impressive durability. These bearings last up to twice as long as standard sleeve bearings, with a lifespan of up to 80,000 hours. They provide consistent, smooth cooling while reducing mechanical wear over time. This results in quieter, more reliable operation and extended hardware longevity, even during prolonged gaming or creative workloads.

0dB Technology for True Silent Operation:

The 0dB Technology built into the ROG Strix 550W automatically stops the fan when total system power draw (TDP) falls below 40%. During light gaming or idle periods, the PSU operates silently, allowing you to enjoy your experience without background noise. Once the system load increases, the fan automatically resumes operation to maintain safe temperatures. This intelligent cooling management ensures the ideal balance between silence and performance.

80 PLUS Gold Certification Efficiency You Can Rely On:

Featuring top-end Japanese capacitors and precision engineering, the ROG Strix 550W Gold achieves 80 PLUS Gold certification, guaranteeing exceptional energy efficiency. This high level of performance ensures that the PSU operates cooler and quieter while minimizing energy waste. The reduced heat output also contributes to a longer lifespan for both the power supply and the components it powers, delivering reliability for years of gaming and productivity.

Cosmetic Customization for Personalized Builds:

Aesthetics are a key part of any premium setup, and the ROG Strix 550W Gold makes personalization simple. It includes a magnetic logo and a selection of custom stickers, allowing you to match the PSU’s visible side to your system’s color scheme or theme. Whether you prefer a minimalist style or a bold ROG-inspired design, the Strix 550W gives you the freedom to make your build truly your own.

Fully Modular Cables for a Clean, Organized Build:

The fully modular design of the ROG Strix 550W Gold makes cable management easy and efficient. You only need to connect the cables required for your specific setup, reducing clutter and improving airflow within your case. The included 24-pin, 6+2-pin PCI-e, and 8-pin CPU cables feature embedded capacitors that help minimize voltage ripple for more stable power delivery. ASUS also includes a CableMod coupon for enthusiasts who wish to customize their cable colors and materials to match their build perfectly.

Compact Powerhouse Built for Modern Gaming:

The ASUS ROG Strix 550W Gold Power Supply embodies the ROG philosophy of innovation, performance, and reliability. Its combination of premium cooling technologies, modular design, and quiet operation makes it a standout choice for gamers and creators who value quality and aesthetics. Whether you’re building a compact gaming rig or upgrading an existing system, the Strix 550W Gold offers the efficiency, durability, and style you need to power your setup with confidence.
