Description
The ASUS ROG Loki SFX-L series redefines power density for small form factor (SFF) enthusiasts. Inheriting the premium DNA of the ROG Thor line, the Loki delivers up to 1000W of 80 Plus Platinum certified power within a compact 125mm chassis. Designed for the next generation of high-performance computing, it features native ATX 3.1 support and a dedicated 16-pin PCIe Gen 5.0 cable to drive power-hungry GPUs like the NVIDIA GeForce RTX 40-series. With its axial-tech cooling and Aura Sync ARGB integration, this PSU balances extreme performance with a striking aesthetic.
This product is for:
- SFF Enthusiasts: Builders creating high-end Mini-ITX systems who require maximum wattage in a restricted SFX-L footprint.
- Next-Gen Gamers: Users upgrading to PCIe 5.0 graphics cards who need a reliable 12VHPWR connection without bulky adapters.
- Silent PC Builders: Individuals prioritizing low noise levels, benefiting from the 0dB fan mode during light to medium workloads.
- Aesthetic-Focused Modders: Builders utilizing the Aura Sync ARGB fan and transparent components to synchronize lighting across their entire rig.
- Professional Workstation Users: Creators needing stable, Platinum-rated power delivery for compact rendering or AI development stations.

Operating the ROG Loki is a seamless experience characterized by thermal efficiency and acoustic control. The 120mm axial-tech fan utilizes dual ball bearings for longevity and features a 0dB mode that keeps the unit completely silent when the load is under 40%. During high-stress gaming or rendering, the fan scales intelligently to maintain low temperatures without the high-pitched whine often associated with smaller SFX units. The fully modular, etched cables are flexible enough for tight cable management in cases like the ROG Z11 or other popular ITX enclosures, significantly improving airflow and build cleanliness.
Compared to the standard ROG Thor series, the Loki offers similar Platinum-grade components but in a significantly smaller SFX-L form factor, making it compatible with compact cases where ATX units cannot fit. While traditional SFX power supplies often use 80mm or 92mm fans, the Loki’s SFX-L design allows for a larger 120mm fan, resulting in superior airflow at lower RPMs. Against competitors in the SFX space, the Loki stands out with its native ATX 3.1 compliance and the inclusion of an ARGB fan, providing a level of visual customization rarely seen in small-form-factor power delivery.
Q&A:
- Does the ROG Loki include an ATX mounting bracket? Yes, the package includes an ATX to SFX adapter bracket for use in larger cases.
- Is this PSU compatible with the NVIDIA RTX 4090? Yes, the 1000W and 850W models include a native 16-pin PCIe Gen 5.0 cable capable of delivering up to 600W to the GPU.
- What is the difference between SFX and SFX-L? SFX-L is slightly longer (125mm vs 100mm), allowing for a larger, quieter 120mm fan while remaining compatible with most ITX cases.
- How does the 0dB fan button work? When engaged, the fan remains off until the power supply reaches a specific temperature or load threshold, ensuring silent operation during idle or light tasks.
- Does the ARGB lighting require a specific controller? The fan connects via a standard 3-pin addressable RGB header on your motherboard and is fully controllable via ASUS Aura Sync.
