ASUS Republic of Gamers Announces ROG Strix 550W Gold Power Supply Unit
550-watt model features premium components, a 10-year warranty, quiet performance, and customizable aesthetics.
ASUS Republic of Gamers (ROG) announced the Strix 550W Gold PSU, which joins the 750 W and 650 W models already in the series. Like its bigger siblings, the 550 W model leverages a potent combination of exclusive ROG cooling technology and premium components to deliver ultra-low-noise operation while fueling the latest multicore processors and graphics cards.
ROG heatsinks and Axial-tech cooling
Low noise is essential for premium gaming rigs, so ROG Strix series power supplies utilize the same heatsinks as the venerable ROG Thor series. A careful balance of mass and surface area allows the PSU to pump out judicious amounts of power before the 135 mm Axial-tech fan needs to spin up. Based on the same design used on high-end ROG Strix graphics cards, Axial-tech fans feature a smaller hub and longer blades connected to a barrier ring which improves static pressure by directing air downwards. Durability is paramount, so the propeller is mounted on a dual-ball-bearing setup that will last up to twice as long as a sleeve-bearing design. When combined with ROG heatsinks, the cooling is so effective that the fan only needs to spin at low speeds, keeping noise levels to a minimum.
Premium components
A robust mix of Japanese capacitors and low RDS(on) MOSFETs provide the foundation for a 10-year warranty and allow Strix series PSUs to achieve 80 PLUS® Gold certification. The result is an incredibly efficient power supply with the endurance to handle the most intense gaming scenarios.
Cosmetic customization
ROG Strix series power supplies are fully modular and are bundled with a full complement of cables ready to hook up to the latest hardware. The 24-pin, two 6+2-pin PCIe®, and two 8-pin EPS 12 V power cables come with embedded capacitors to reduce ripple and ensure stability when the going gets tough. For users who wish to personalize their build, the package also includes a 20% discount coupon courtesy of CableMod, granting access to custom cable materials, lengths, and colors. Further customization is made possible by a convenient magnetic logo and a range of decals that can be used to reskin the visible sides of the PSU. The default red slash can be switched to neutral colors for a stealthier vibe or provide the ideal backdrop for an all-ROG Strix system accented with Aura Sync RGB lighting.
