ASUS ROG LOKI SFX-L Platinum 850W Modular Power Supply

The ASUS ROG-LOKI-850P-SFX-L-GAMING is a power supply built for builders who want high wattage inside a small case. It follows the SFX-L form factor yet delivers 850 W of stable output, making it a natural fit for Mini-ITX gaming rigs or compact workstations that still run flagship processors and graphics cards.

An 80 PLUS Platinum efficiency rating keeps wasted energy and excess heat to a minimum. The fully modular design means you attach only the cables your components require, so airflow improves and clutter stays out of tight spaces.

Cooling comes from a 120 mm fan that uses dual ball bearings and PWM control. The fan remains off during light workloads and ramps up smoothly when the system demands more power, helping your build stay quiet during everyday tasks and cool during intense gaming sessions.

The bundled 16-pin PCIe 5.0 cable can deliver up to 600 W to a compatible GPU, removing the need for adapters and preparing the system for next-generation graphics cards. Premium Japanese capacitors handle heavy loads with consistent voltage, while a comprehensive set of protection circuits guards every connected component.

Addressable RGB lighting around the fan integrates with Aura Sync, so even a small-form-factor build can join a synchronized lighting setup. With its high power density, quiet operation, and advanced cabling, this unit suits enthusiasts, content creators, and anyone who wants a clean, powerful rig without the bulk of a standard ATX power supply.
