Quiet Performance with Advanced Cooling
ROG heatsinks and a 120 mm ARGB fan keep temperatures low while maintaining near-silent operation. The PSU supports 0dB mode at light loads, so your SFF build stays whisper-quiet during everyday use. Japanese capacitors improve efficiency and reduce heat, ensuring reliable long-term performance.
Future-Proof ATX 3.0 Ready
ROG Loki steps ahead of the curve with full ATX 3.0 compliance, meeting tighter voltage and current regulation standards for next-gen hardware. A bundled 16-pin PCIe cable supports up to 600 W for PCIe Gen 5.0 graphics cards, bringing large-scale capabilities to compact systems.
Customisable ARGB Lighting
The 120 mm fan features eight addressable LEDs ready for Aura Sync integration. Coordinate lighting patterns across your build for a cohesive look. Note that Aura Sync requires a compatible ASUS or ROG motherboard, and Smart Mode lighting needs a compatible graphics card.
