ASUS ROG Strix GeForce RTX 4090 OC review: Fast and furious
Note: This review was first published on 31 October 2022.
The ASUS ROG Strix GeForce RTX 4090 OC makes a beastly card even beefier. With the GeForce RTX 4090 already topping performance benchmarks and setting a new standard for what 4K gaming numbers should really look like, the question of which custom card to buy will largely come down to looks and each card's unique cooling solution.
The ASUS card is massive, making the already gargantuan Founders Edition model look svelte in comparison. It measures a good 357mm long, which means that clearance could possibly become an issue in some cases. Even the popular NZXT H510 Elite will find the card a tight fit — plus, there will be zero room for any front-mounted radiator.
But if you have a smaller chassis like the H1 or H210, the card will most definitely not fit.
This is also a 3.5-slot card, or basically four slots in practice. However, the IO bracket only takes up two slots.
If you're worried about the card sagging and damaging your PCIe slot in the long run, an included graphics card holder should help provide some additional support.
It owes its expansive girth to the ridiculously chunky heatsink. The heatsink fins sit 90 degrees relative to the length of the card, which means that hot air is exhausted out the top of the card instead of being vented toward the back. This may be something to take note of if you're planning the orientation of your case fans.
A GPU bracket provides extra stability to the critical connection between the die and heat spreader. This is paired with the diecast shroud, frame, and backplate for improved rigidity.
In terms of aesthetics, the latest generation of ROG Strix cards looks considerably changed from the GeForce RTX 3000 series. It features rounded corners, red and purple detailing, and a striking cap at the end of the card that is illuminated by RGB lighting. However, save for a backlit Republic of Gamers text line on the side, the rest of the card is notably devoid of any other ostentatious lighting.
Three 104mm axial-tech fans help pull cool air over the heatsink. These are slightly larger than the previous generation design and are rated for 23% more airflow, according to ASUS. The middle fan also rotates clockwise, while the outer ones rotate anti-clockwise, which is supposed to help reduce air turbulence and fan noise.
A dual BIOS switch on the card's edge allows you to quickly switch between performance and quiet speed profiles without having to enter the software. A new power sensing indicator also lets you know if something is up with your PSU. Featuring a high-speed circuit that monitors input power from your PSU, it will let you know if there are voltage regulation issues or cable connection problems.
The GeForce RTX 4090 uses NVIDIA's new 16-pin power connector. ASUS is recommending a whopping 1000W PSU to go with it, so you might have to swap out more than one component in your system if you're planning for this card.
Display outputs include two HDMI 2.1 and three DisplayPort 1.4 connectors, but you can only output to four displays at any one time. It is almost mind-boggling that NVIDIA hasn't included support for DisplayPort 2.0, considering that the standard was finalised way back in 2019.
