EK®, the leading manufacturer of premium liquid cooling gear, is bearing good news for liquid cooling enthusiasts, announcing the availability of compatible GPU water blocks for the OG Editions of the ASUS® TUF Gaming GeForce RTX™ 4090 graphics cards. Due to the physical differences in the PCB of the OG Edition GPU, it requires a different GPU water block than what would usually fit the 4090 Strix and TUF models.

After researching the market and examining the GPU itself, EK’s RnD team has concluded that the OG Edition 4090 TUF is compatible with the EK-Quantum Vector² Strix/TUF RTX 3090 Ti water block and EK-Quantum Vector² Strix/TUF RTX 3090 Ti ABP (Active Backplate) Set. The models of the GPU are not to be confused with the “OC” marking but with the newly added “OG” suffix in the product name. Here, EK would like to thank the Reddit community as a useful source of information.

TUF 4090 PCB Vs. TUF 4090 OG Edition PCB 

The PCB of the ASUS TUF Gaming GeForce RTX 4090 and its OC variant is shown on the left, while the PCB of the OG Edition and its OC variant are shown on the right. They have visible physical distinctions: from the shape and size of the PCB to the components used. The OG variant is easily identifiable by the large PCB.

This is why the ASUS TUF RTX 4090 OG Edition is compatible with:

• EK-Quantum Vector² Strix/TUF RTX 3090 Ti water block
• EK-Quantum Vector² Strix/TUF RTX 3090 Ti ABP Set
