ASUS ROG Loki 1200T SFX-L Gaming – 1200W Titanium Power for SFF Builds

The ASUS ROG Loki 1200T SFX-L Gaming PSU is engineered to deliver flagship-level performance in a compact SFX-L form factor. Designed for high-end small form factor (SFF) builds, this 1200W power supply combines exceptional efficiency, ultra-quiet operation and premium ROG aesthetics.

With 80 PLUS Titanium certification, the ROG Loki achieves up to 94% energy efficiency under typical loads. This high efficiency reduces heat output, lowers power consumption and enhances long-term reliability. It is also certified to Cybenetics Titanium standards and meets the Cybenetics Lambda Standard++ for exceptionally quiet operation.

Despite its compact 125 x 125 x 63.5 mm SFX-L dimensions, the Loki delivers immense power suitable for enthusiast-grade gaming systems. It is PCIe Gen 5.1 ready and includes a native 16-pin cable capable of supplying up to 600W to next-generation graphics cards, ensuring full compatibility with modern high-performance GPUs.

Built with tight voltage and current regulation, the ROG Loki provides stable and precise power delivery, even during intense gaming sessions or heavy workloads. Premium internal components help maintain consistent output while protecting your system against power fluctuations.

Cooling is handled by a high-performance fan designed for minimal noise output. The PSU operates quietly even under demanding loads, making it ideal for compact systems where airflow and acoustics are critical considerations.

Adding signature ROG styling, the ARGB-illuminated fan supports Aura Sync, allowing seamless synchronization with compatible motherboards and components. This enables you to coordinate lighting effects across your entire gaming setup for a cohesive aesthetic.

Whether you are building a powerful compact gaming PC or a premium SFF workstation, the ASUS ROG Loki 1200T SFX-L Gaming PSU delivers unmatched power density, efficiency and quiet performance in a space-saving design.
