ASUS ROG -LOKI-1200T-SFX-L-GAMING power supply unit 1200 W 20+4 pin ATX Black, Silver

The ASUS ROG Loki 1200W SFX-L Titanium is a compact high-performance power supply designed for small form-factor (SFF) gaming systems. Built with enthusiast-grade components and an SFX-L form factor, it combines quiet operation, ATX 3.0 compatibility, and a 1200 W maximum output to support powerful GPU and CPU configurations in compact builds.

Advantages

The unit features 80 PLUS Titanium-level efficiency with low-ESR Japanese capacitors to reduce heat and improve longevity. An advanced cooling design includes ROG heatsinks, a 120 mm fan with dual ball bearings for increased lifespan, and 0dB technology that stops the fan under low loads to minimize noise. It emits under 35 dB on average and holds Cybenetics Lambda ++ certification. The PSU is ATX 3.0 compatible and ships with a 16-pin PCIe cable capable of delivering up to 600 W to PCIe Gen 5.0 graphics. The fan includes addressable ARGB lighting compatible with ASUS Aura Sync, and the product is backed by a 10-year warranty for core operation.

How to use

Install the ROG Loki SFX-L 1200W into an SFX-L compatible case following the case and motherboard manufacturer instructions. Connect the 20+4 pin ATX cable to the motherboard and attach required PCIe power connectors to GPUs using the provided modular cables; use the supplied 16-pin PCIe cable for compatible PCIe Gen5 graphics cards when higher single-cable power delivery is needed. Ensure mains input matches the supported range (100–240 V) and secure cable routing to avoid obstructing airflow. Configure ARGB lighting by connecting the lighting cable to an Aura Sync-compatible ASUS/ROG motherboard if synchronized lighting is desired.

Recommendations

For sustained high-load operation, ensure your case has adequate airflow and keep dust filters clean. Use the included 16-pin PCIe cable only with compatible graphics cards and check GPU manufacturer guidance for power delivery. Note that RGB Smart Mode and full Aura Sync functionality require compatible ASUS/ROG motherboard or graphics card connections.
