Asus ROG LOKI SFX-L 850W Platinum Power Supply

The ROG LOKI SFX-L 850W Platinum delivers enthusiast-grade power in a compact SFX-L form factor, measuring just 125 x 125 x 63.5mm. Built for high-performance small form factor builds, this fully modular PSU combines quiet operation with 80+ Platinum efficiency for reliable power delivery.

PCIe 5.0 and ATX 3.0 Ready

Equipped with a 16-pin PCIe Gen 5.0 cable capable of delivering up to 600W to next-generation graphics cards. The ATX 3.0 compatibility ensures tighter voltage regulation and current control for stable power delivery to modern components.

Advanced Cooling Technology

The 120mm Axial-tech fan features a smaller hub design with longer blades and a barrier ring for increased downward air pressure. Dual ball bearings provide twice the lifespan of sleeve bearing designs. The PWM-controlled fan incorporates 0dB Technology, shutting off completely when PSU load drops below 40% for silent operation during light workloads.

Premium Components and Efficiency

80+ Platinum certification guarantees up to 92% efficiency, reducing heat output and improving reliability. Low-ESR Japanese capacitors and ROG heatsinks facilitate lower temperatures and extended component lifespan. The efficient design minimizes energy waste and reduces operating costs.

ARGB Lighting and Aura Sync

Eight addressable RGB LEDs illuminate the 120mm fan, ready for customization through Aura Sync when paired with compatible ASUS or ROG motherboards. The default rainbow effect activates without additional connections.

Comprehensive Connectivity

Fully modular design includes: 1x 24/20-pin motherboard connector, 2x 4+4-pin CPU cables, 1x 16-pin PCIe Gen 5 cable, 3x 8-pin PCIe cables, 6x SATA connectors, and 4x peripheral connectors. An ATX-to-SFX adapter bracket enables installation in standard ATX cases.

Protection and Warranty

Multiple protection mechanisms include OPP, OVP, UVP, SCP, OCP, and OTP safeguards. Backed by a 10-year warranty on core operation (3-year warranty on RGB LEDs), demonstrating long-term reliability for demanding builds.
