ROG Strix GeForce RTX 4080 review: More efficiency for less power
Much like its more powerful Strix GeForce RTX 4090 OC, the ROG Strix GeForce RTX 4080 OC is one beastly-looking graphics card. In fact, you will be hard-pressed to find any difference between both cards in terms of looks and designs – these Strix cards are literally one and the same on the surface.
That means the ASUS card is equally massive, and at 357mm long, clearance could possibly become an issue in some PC cases. Even popular ones such as the NZXT H510 Elite will find the card a tight fit — plus, there will be zero room for any front-mounted radiator. This is also a 3.5-slot card, or basically four slots in practice. However, the IO bracket only takes up two slots.
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.
In terms of aesthetics, the Strix RTX 4080 features rounded corners, red and purple detailing, and a striking cap at the end of the card that is illuminated by RGB lighting. There’s also a backlit Republic of Gamers text line on the side. It’s all very nice. It’s also very familiar if you have read our ROG Strix RTX 4090 OC review.
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 Strix RTX 4080 includes two HDMI 2.1 and three DisplayPort 1.4 display connectors, but you can only output to four displays at any one time. Unsurprisingly, it also uses the NVIDIA-mandated 16-pin power connector.
