ASUS unveils giant GeForce RTX 4090 and RTX 4080 builds from ROG Strix and TUF Gaming

ASUS has unveiled the GeForce RTX 4090, RTX 4080 16GB, and RTX 4080 12GB graphics cards in their proprietary ROG Strix and TUF Gaming designs. The new products received a refreshed design of cooling systems, which have become much larger and more efficient than their predecessors. However, this is not surprising since the manufacturer specifies a power consumption of up to 500 W for new cards.

The GeForce RTX 4090 ROG Strix model received a huge cooling system with a thickness of 3.5 expansion slots. It features a die-cast metal frame for durability, as well as a metal back reinforcement plate to prevent the card from bending under its weight. The length of the accelerator is an impressive 357 mm. The company does not provide any information about the mass of new releases.

The manufacturer has completely revised the cooling system. It uses a new heatsink and a new evaporating chamber with a 30% larger heat dissipation area. For even higher heat transfer efficiency, four heat pipes with a diameter of 8mm and three with a diameter of 6mm are literally embedded in the vaporization chamber itself, where special channels are made with a milling machine.


The GeForce RTX 4090 ROG Strix cooling system received larger seven-blade fans equipped with a locking ring. The “propellers” provide 23.8% more efficient airflow and 19.3% higher static pressure than the previous generation fans on the ROG Strix GeForce RTX 3090 model. Not much has changed compared to the previous generation. It is also noted that the “turntables” perform the function of a complete stop in the absence of a load.

The card uses a 12+4 phase power split system with phases of 70A. Since each phase has two power stages, the total is 24+4.

In the performance of TUF Gaming, the GeForce RTX 4090 model has a thickness of 3.65 expansion slots. The length of the graphics card is 348 mm. It also features a metal backplate and frame for durability.

The cooling system of this version features new fans with 20% more airflow, a new heatsink and evaporator chamber with 35% more contact area, and eight heat pipes (five 8mm and three 6mm). The power supply subsystem of the novelty is built according to the 10 + 4 scheme with two power stages for each phase.

ASUS GeForce RTX 4090 graphics cards in Strix and TUF Gaming versions are equipped with dual BIOS systems with sleep and performance modes. The necessary additional performance for the accelerators is provided via a new 12+4-pin PCIe 5.0 connector.

The thickness of the “longer” model ROG Strix GeForce RTX 4080 16GB is 3.5 expansion slots, and the length of the graphics card is 357mm. At the same time, the thickness of the TUF Gaming GeForce RTX 4080 accelerator is 3.65 expansion slots, but the card is 9mm shorter.

The ROG Strix GeForce RTX 4080 12GB model has a thickness of 3.15 expansion slots and a length of 336mm. In the TUF Gaming version, the thickness of this accelerator is 3.25 expansion slots and the length is 305mm. All presented versions of the GeForce RTX 4080 from ASUS, like the older GeForce RTX 4090, received dual BIOS systems and updated cooling systems.

Curiously, ASUS recommends power supplies from the new Thor and Loki series with a power of 1000 W or more for its new products.
