ASUS reveals first ‘true’ 16-pin power connector for next-gen GPUs

ASUS has showcased its upcoming LOKI series of power supplies. This is the second line of power supplies to feature 16-pin power cabling for next-gen GPUs.

It should be noted that the already released high-end Thor series do in fact come with next-gen PCIe Gen5 cables, however, the connection is achieved using adapters. The new LOKI power supply will feature the first ‘true’ PCIe Gen5 connector with all 16 pins present.

NVIDIA’s 12-pin Molex MicroFit 3.0 cable is only a partial implementation of the Gen5 connector. While both cables feature 12 pins, the Gen5 standard comes with additional 4 data paths. According to rumored specs, those are optional.

In the case of new small factor pc PSUs called ROG Loki, those data cables appear to be present, which means this is indeed the first full implementation of the standard.

The first graphics card to feature a 16-pin power cable is the upcoming RTX 3090 Ti graphics card, the flagship NVIDIA Ampere gaming card. As confirmed by ASUS, this connector alone will offer up to 600W of power. A rumored custom RTX 3090 Ti card from EVGA is rumored to require two of such cables, allowing up to 1275W of power.

Large showcase rigs will always be the lifeblood of the PC building community, but small form factor (SFF) builds have become increasingly popular in recent years. It’s easy to see why: if you 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, so you can build your next console clone without compromises.

Hot on the heels of our latest 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 1200W, 1000W, 850W, and 750W variants, the ROG Loki series provides enough power for even the most high-end SFF PCs, with top-tier efficiency. The 1200W 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 small form factor PCs. The ROG Loki 1200W 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.

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, Loki features a slew of protection mechanisms to ensure the highest level of safety.

Heat is the largest challenge when designing small form factor machines, particularly at such high wattages. Since small form factor 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 from our 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 120mm 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 you to flex your style, with Aura Sync compatibility allowing you to match lighting effects across your entire system.

Finally, the ROG Loki series is fully modular, allowing you to use only the cables you absolutely need—which is crucial for space-starved SFF cases. The Loki is even PCIe Gen 5.0 ready, bundled with a 16-pin PCIe cable that can pipe up to 600W of power to modern compatible graphics cards.

The ROG Loki series is backed by a 10-year warranty*, so you can feel confident using it as the backbone of your next SFF build. For more information on pricing and availability of ROG Loki power supplies in your region, please contact your local ASUS representative.

*Core product operation is guaranteed for 10 years. The RGB LEDs are covered by a 3-year warranty.
