SYDNEY, Australia, September 5, 2022 — ASUS Republic of Gamers (ROG) today announce d the availability of the ROG Loki — the high-performance, high-wattage PSU series in a striking SFX-L form. Packed with large ROG heatsinks for rapid cooling, integrated ARGB lighting to project personal style and axial-tech fans for whisper-quiet operation, the Loki series is pumped and primed to power small-form-factor (SFF) builds.
All set for SFF
Large showcase rigs will always be the lifeblood of the PC-building community, but SFF builds have become increasingly popular in recent years. It's easy to see why: for those that want a build that can comfortably fit on a smaller desk, or in an entertainment center for TV gaming, a Mini-ITX machine is the perfect choice. But cramming next-gen power into a tiny case can be a challenge, especially with the added heat those components can produce. ROG's new Loki power supplies were designed to keep efficiency up and footprint down, empowering avid PC DIYers to build no-compromise, console-crushing clones.
Following on from the ROG Thor PSUs, the Loki series takes the same high-quality components and packs them into an SFX-L form factor for Mini-ITX rigs — the perfect companion to a PC built on the ROG Strix Z690-I Gaming WiFi motherboard.
Available in 1200 W, 1000 W, 850 W, and 750 W variants, the ROG Loki series provides enough power for even the most high-end SFF PCs, with top-tier efficiency. The 1200 W model is the highest-capacity SFX-L PSU available on the market, marking an incredible achievement in engineering and an excellent opportunity for builders pushing the limits of the SFF PCs. The ROG Loki 1200 W also reaches the incredibly stringent efficiency levels set by the 80 PLUS ® Titanium certification, achieving greater than 90% efficiency from loads as low as 10% all the way up to maximum output. The other models sport the 80 PLUS Platinum badge. Both the 750 W and 850 W models have achieved Lambda certification from Cybenetics for low noise. Specifically, the 850 W model operates at a whisper-quiet of 25 dB for Lambda A status, while its 750 W sibling even more peaceful — emitting a barely-audible 20 dB to secure Lambda A+ certification.
The low-ESR Japanese capacitors inside each unit are rated to last twice as long as standard caps, with up to 45% less equivalent series resistance — an efficiency boost that results in better reliability with less heat. And of course, the Loki features a slew of protection mechanisms to ensure the highest level of safety.
Efficient heatsink and ARGB fan
Heat is the largest challenge when designing SFF machines, particularly at such high wattages. Since smaller PCs rarely have as much airflow as their larger brethren, our engineers needed to find a way to dissipate the heat generated inside these power-dense supplies. After countless hours of experimentation, they were able to renew the PCB design and cooling system to provide the stable, reliable power we demand and consumers expect from ROG products.
Part of that was developing a heatsink with twice the volume of traditional designs, allowing for better heat dissipation and lower hotspot temperatures. The dual-ball fan bearings also allow for greater longevity in the 120 mm fan, which uses our axial-tech design for higher air pressure than typical power supplies. The Loki's fan isn't just functional, either — the ARGB fan allows builders to flex their style, with Aura Sync compatibility allowing lighting effects to be harmonized across an entire system.
Modular design, ATX 3.0 ready, and 10-year warranty
Finally, the ROG Loki series is fully modular, stripping back cabling requirements to the absolute minimum — a crucial factor for space-starved SFF cases. The Loki is compliant with the latest ATX 3.0 standard and is also PCI Express ® 5.0-ready, being bundled with a 16-pin PCIe ® cable that can pipe up to 600 W of power to compatible graphics cards.
The resilient ROG Loki series is also backed by a 10-year warranty [1] , giving consumers the confidence and reassurance needed for using it as the backbone of their next SFF build.
