ASUS ROG Loki 850W SFX-L Fully Modular 80+ Platinum Power Supply

The ASUS ROG Loki 850W is a high-performance SFX-L form factor power supply unit designed primarily for small form factor (SFF) PC builds. It delivers 850 watts of continuous power with 80 Plus Platinum certification, indicating exceptional electrical efficiency that reduces heat output and operating costs. The unit is fully modular, allowing users to connect only the cables needed for their specific components, which significantly improves airflow and cable management within compact cases. This makes it an ideal choice for enthusiasts building powerful systems in space-constrained environments. The power supply incorporates several advanced features for reliable and quiet operation. It uses a 120mm Axial-Tech cooling fan with dual ball bearings, which ASUS claims lasts twice as long as traditional sleeve-bearing designs while providing increased downward air pressure. The fan is PWM-controlled and features addressable RGB lighting with eight LEDs that can be customised via ASUS Aura Sync when connected to a compatible motherboard. For silent operation, the unit includes 0dB technology that stops the fan entirely when the load is at 40% or lower. Internally, it employs a large ROG-branded heatsink and low-ESR Japanese capacitors to ensure stable power delivery and extended component lifespan. This PSU is particularly well-suited for gamers and PC builders creating high-end, compact systems that require clean power for components like the latest graphics cards and processors. Its SFX-L form factor is slightly larger than standard SFX units, offering more room for the high-quality components typically found in larger ATX power supplies. The unit is also PCI Express 5.0 ready, ensuring compatibility with next-generation graphics cards. The combination of high efficiency, modular cabling, and intelligent cooling makes it a practical solution for anyone seeking reliable performance without compromising on space or acoustics.
