If you want to make a statement with the best gaming card money can buy, look no further than the new ROG Strix GeForce RTX 4090. With unprecedented power, this card is designed for ultra-high resolutions or super-fast refresh rates that help you reign supreme on the battlefield.

In order to extract the ultimate performance from the Strix GeForce RTX 4090, we built it with cooling as our top priority. The card’s 3.5-slot design consists of a die-cast metal frame, shroud, and backplate. The ultra-rigid structure uses frames with extremely tight tolerances to prevent the PCB from sagging or warping, while still allowing for unparalleled airflow through an enlarged pass-through vent along the back of the 357mm long card.

But with an ultra-powerful GPU like the GeForce RTX 4090, we wanted to go further than a large heatsink and vented backplate. So we rebuilt the heatsink design from the ground up, with a new vapor chamber and 30% more surface area for heat dissipation than the previous generation ROG Strix GeForce RTX 3090.

This is no ordinary vapor chamber, however. In order to provide better heat transfer, this patented vapor chamber design adds milled channels underneath the heatpipes. Instead of the pipes lying flat against the surface, they sink into the vapor chamber, allowing more heat to efficiently transfer to the four 8mm and three 6mm heatpipes and travel to the heatsink fins. When subjected to a 500W thermal load, this potent pairing allows for 5°C cooler temperatures than a conventional vapor chamber design.

We also upgraded the Axial-tech fans, with a thicker design featuring 7 blades and full barrier rings that provide 23.8% more airflow and 19.3% more pressure than the previous generation fans used on the ROG Strix GeForce RTX 3090. With these improvements, we were able to keep GPU temperatures and acoustics at similar levels to the previous generation model, despite the extra power.

Speaking of power: this is an absolute monster of a gaming card, so we’ve included a 12+4 phase system comprising 70A power stages. With two power stages per phase fueling the GPU, that’s a total count of 24+4. The digital controller on board offers higher precision when detecting power, as well as better power conversion and balancing for less noise and signal interference. With a quality power supply in place (like our ROG Thor 1200P2), you should have no problem driving this beast of a graphics card, and with native 16-pin PCIe support, you can do it without any adapters required.

All of this comes with the same high-end features ROG Strix cards are known for. An ARGB tail-light works with Aura Sync to offer customized lighting across your build, while two FanConnect II headers allow you to control your case fans with your GPU temperature through our new GPU Tweak III software. For those who don’t want to dig in and tweak too much, the Dual BIOS switch allows you to choose between maximum performance mode and a quieter mode. Though thanks to our 0dB technology, the card will be silent at low loads no matter which mode you choose.

Finally, like our other ROG cards, the Strix GeForce RTX 4090 was built with our Auto-Extreme manufacturing process that minimizes human intervention, so you can expect reliable long-term performance right out of the box.

Impressive cooling capabilities and a good looking card

by William star star star star star

Best looking RGB 4090 with very good cooling to top it off.


Tormentor

by Menator star star star star star

I thought for a long time about which graphics card to choose. I chose the 4090 OC and I do not regret it. I have an i7 7700K processor. On the Internet, on various forums, they write that this processor is too weak for this card. Not true! It probably limits it a bit, but in games I have over 120-240 fps. If someone has doubts whether to buy such a card for this processor, there is nothing to worry about. I previously had a GTX 1080 Ti STRIX. Unfortunately, this card is already too weak for current games. Ray Tracing on the RTX 4090 OC asus ROG looks amazing. Only the price is too high and the lack of DisplayPort 2.1 support hurts a bit. I recommend this card with a clear conscience.


Awesome Size , Fantastic Power

by Techsponge star star star star star

Firstly check your pc case is big enough to handle this massive Card. I went from a 3090 to this and it dwarfs the 3090. The high frame rates you can achieve are amazing. You are getting what you paid for. Note i recommend you get a support bracket . Ultra settings are easily achieved in games and the card itself is beautiful with its aura lighting. A card to recommend
