The ASUS ROG Loki SFX-L 850W power supply is the best choice for those who are looking for excellent performance and reliability for their computer. With quiet operation and high performance, it is the perfect solution for building SFF (small-scale) machines. It has 80 PLUS Platinum certification, which guarantees extremely efficient energy use.

Effective cooling
ROG cooling fins - Cool even under load
ROG heatsinks make it easier to achieve lower temperatures, provide longer life and can continue to operate with 0 dB noise level (i.e. silently).

Axial-tech fans - Better, faster, more powerful
Due to the axial fan technology, the fan shaft can have a smaller diameter and the blades are longer, and they are also surrounded by a boundary ring, which increases the downward air pressure. For the ROG Loki power supplies, a 120 mm version of this solution was used, which is able to keep the components cool even at low rpm, and at the same time is even quieter.

Double ball bearing fan - Twice as long service life
The impeller of the fan has double ball bearings. The service life of such structures can be twice as long as that of sliding bearings.

0 dB technology - Silent intelligence
To reduce noise emissions, the PWM-controlled fan stops completely when the load on the power supply drops below 40%.

Lambda A rating - Quiet and other
ROG Loki emits less than 25dB of noise, earning it the coveted Cybenetics Lambda A certification.

Engineering solutions
80 PLUS Platinum rating - Output power without effort
Japanese-made capacitors with low internal resistance further improve efficiency and reduce heating, allowing ROG Loki to provide reliable power supply to your built-in system for years to come.

ATX 3.1 compatible - A step into the future
ATX 3.1 requires stronger voltage and current regulation for the latest hardware - and ROG Loki already delivers. The 16-pin PCIe cable included with the power supply is capable of supplying 600 watts of power to PCIe Gen 5.1 graphics cards, thus bringing the performance previously only available in larger sizes to smaller (SFF) systems.

User experience
Fan with ARGB lighting and Aura Sync - Magic glow
Loki's 120mm fan has eight addressable LEDs that can be customized with the Aura Sync function, all elements of the built system can display uniform lighting effects.

10-year warranty - A decade of energy
The ROG Loki SFX-L 850W Platinum guarantees such reliable performance that the manufacturer guarantees it for 10 years.
