ASUS ROG Loki SFX-L 750W Platinum power supply unit 20+4 pin ATX Black, Silver

The ASUS ROG Loki SFX-L 750W Platinum is a fully modular SFX-L power supply designed for small form factor (SFF) gaming and enthusiast PCs. With 750 W total output, 80 PLUS Platinum efficiency and a 120 mm ARGB-illuminated fan, the unit combines compact dimensions with high performance and compatibility for next-generation hardware.

Advantages

The ROG Loki uses enthusiast-grade components including low-ESR Japanese capacitors and dedicated ROG heatsinks to lower operating temperatures and extend component lifespan while enabling extended 0dB operation. ATX 3.0 compatibility and a bundled 16-pin PCIe cable allow up to 600 W feeding of PCIe Gen5 graphics cards in compact builds. The fully modular layout simplifies cable management inside SFX-L cases, and addressable RGB on the 120 mm fan integrates with Aura Sync for coordinated lighting.

Suitable for

• Small form factor gaming PCs and compact enthusiast builds
• Systems using PCIe Gen5 graphics cards that require ATX 3.0 power delivery
• Builds where efficient, quiet operation and neat cable management are priorities

How to use

Install the ROG Loki into an SFX-L compatible chassis, secure the unit and connect the fully modular cables to your components following the motherboard and GPU manufacturer guidelines. If using a PCIe Gen5 graphics card, attach the supplied 16-pin PCIe cable to the GPU and PSU to provide up to 600 W as required. Connect the 20+4 pin ATX cable to the motherboard and add other modular cables for drives and peripherals. Ensure the PSU is connected to an appropriate AC source (100–240 V) and verify all connectors are seated correctly before powering on the system.

Recommendations

For Aura Sync lighting and Smart Mode GPU-temperature lighting effects, use an Aura Sync–compatible ASUS or ROG motherboard and, if using Smart Mode, a compatible ASUS or ROG graphics card. If the ARGB connector is not connected, the fan defaults to a rainbow color effect. Follow standard safety and grounding procedures during installation and allow adequate airflow around the unit to maintain efficiency and longevity.
