ASUS ROG LOKI SFX-L Platinum 750W Modular Power Supply

The ASUS ROG-LOKI-750P-SFX-L-GAMING is a power supply designed for builders who want serious wattage in a small form factor case. It provides 750 watts of continuous output through a single +12 volt rail, giving modern CPUs and graphics cards the consistent power they need without the bulk of a standard ATX unit.

Energy efficiency sits at the heart of this model. It carries an 80 PLUS Platinum rating and reaches up to 92 percent efficiency at a 50 percent load, which means less wasted power and lower heat in tight enclosures. The PSU also holds a Lambda A certification for noise, confirming that it stays below 25 decibels under typical conditions.

Cooling comes from a 120 mm fan that uses dual ball bearings for long life and PWM control for smooth speed adjustments. When system demand sits under 40 percent, the fan stops completely, creating silent operation during light tasks. Large internal ROG heatsinks and premium Japanese capacitors help dissipate residual heat and maintain stable voltages even during heavy gaming or content creation sessions.

The fully modular cable design lets you attach only the leads your build requires, making it easier to manage cables in compact SFX-L cases. A 16-pin PCIe 5.0 connector capable of supplying up to 600 watts is on hand for the newest graphics cards, and the unit follows the ATX 3.0 specification to support future hardware launches. An integrated ARGB fan that synchronizes with Aura Sync lighting allows the PSU to blend seamlessly with the visual theme of an ROG system.

Whether you are building a high-end Mini-ITX gaming rig, a compact workstation for creative projects, or a living-room PC that needs to stay quiet, this power supply offers a balance of size, efficiency, and headroom that keeps your system both tidy and powerful.
