Description
The ASUS ROG LOKI SFX-L 1200W represents a significant milestone in power density, inheriting the premium DNA of the ROG Thor series but optimized for compact chassis. This unit achieves 80 PLUS Titanium certification, ensuring up to 94% efficiency under typical loads, which translates to less heat and lower energy consumption. With its SFX-L footprint, it bridges the gap between traditional ATX power and the space constraints of Mini-ITX builds, featuring a 120mm Axial-tech fan for superior thermal management and a 10-year warranty for long-term reliability.
This product is for:
- SFF Enthusiasts: Builders utilizing Mini-ITX or small-volume cases who require maximum wattage without sacrificing internal space.
- High-End Gamers: Users running NVIDIA GeForce RTX 40-series or upcoming 50-series GPUs that demand dedicated 16-pin PCIe 5.0 power connectors.
- Professional Workstation Users: Creators using high-core-count CPUs and power-intensive peripherals in compact workstations.
- Silent PC Builders: Those prioritizing low noise levels, as the 0dB technology keeps the fan idle during low-to-medium workloads.
- Aesthetic-Focused Builders: Users who want synchronized lighting via Aura Sync to match their PSU with the rest of their ROG ecosystem.

Operating the ROG LOKI 1200W provides a seamless experience for high-performance computing. The fully modular cable design simplifies cable management, which is critical in tight SFF enclosures where airflow is paramount. The inclusion of high-quality Japanese capacitors ensures long-term reliability and tight voltage regulation. During intensive gaming sessions, the 120mm fan remains remarkably quiet compared to standard 80mm or 92mm fans found in smaller SFX units, and the ARGB lighting adds a customizable visual element that is often missing in high-efficiency power supplies.
Compared to standard ATX power supplies, the ROG LOKI 1200W offers a significantly smaller footprint while maintaining the same 1200W capacity, making it versatile for both small and large cases via the included ATX adapter bracket. When compared to standard SFX units, the SFX-L (Large) format allows for a 120mm fan instead of a 92mm fan, resulting in lower RPMs and reduced noise levels for the same cooling performance. Unlike the Platinum-rated Loki models, this Titanium version offers the highest possible efficiency tier, reducing waste heat in thermally sensitive SFF builds.
Q&A:
- What is the benefit of ATX 3.1 over previous standards? ATX 3.1 introduces stricter voltage and current regulation to handle the high power excursions common in modern high-performance GPUs.
- Can this PSU power an RTX 4090? Yes, it includes two 16-pin PCIe Gen 5.0 cables capable of delivering up to 600W each directly to the GPU.
- Does it fit in a standard mid-tower case? Yes, the package includes an ATX-to-SFX adapter bracket, allowing it to be mounted in standard ATX chassis.
- How does the 0dB mode work? The fan is programmed to remain stationary when the system load is below a specific threshold, ensuring silent operation during light tasks.
- Is the ARGB lighting compatible with other brands? The ARGB cable uses a standard 3-pin header, making it compatible with ASUS Aura Sync and other motherboard lighting software.
