All cables are fully modular, with the motherboard, CPU, and PCI-e cables using embedded capacitors for reduced voltage ripple.

In addition to RGB lighting, the ASUS Republic of Gamers Strix 550W 80 Plus Gold also features additional cosmetic customization. Users can choose between three different ROG Strix label skins, two Join the ROG badges, and a magnetic ROG logo to choose the look that best fits their build. This power supply also incorporates ROG Thermal Solution, and features over-power, over-voltage, short-circuit, over-current, and over-temperature protections.

ROG Heatsinks

The integrated ROG heatsinks have twice as much volume as traditional designs, resulting in lower temperatures inside Strix PSUs. This extends the lifespan of components and allows 0 dB operation for a longer duration than standard designs.

Axial-Tech Fan Design

Originally the result of R&D efforts for ROG graphics cards, Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure. The enhanced efficiency allows the fan to keep things cool at low RPMs, resulting in less overall system noise and increased component lifespan.

Dual Ball Fan Bearings

The ROG Strix 550W 80 PLUS PSU is built with a dual ball bearing setup that will last up to twice as long as a sleeve bearing design.

0 dB Technology

An onboard controller brings the 135mm fan to a standstill when total draw power (TDP) is below 40%, letting you enjoy light gaming in relative silence. Above 40% TDP, the fans automatically start up again.

80 Plus Gold Certification

Japanese capacitors ensure efficient operation and have helped the Strix earn an 80 PLUS Gold certification. The increased efficiency also results in less heat, reducing noise and increasing reliability.

Cosmetic Customization

Getting everything looking right can be a challenging aspect of any setup. The ROG Strix Series PSUs aim to make your life a little easier with a convenient magnetic logo and stickers that help you reskin the visible side to your liking.

Fully Modular Cables

Keep your rig neat and tidy with fully modular cables. One 24-pin, two 6+2-pin PCI-e, and two 8-pin CPU cables come with embedded capacitors that reduce voltage ripple.
