White OC Edition for 4K gaming

The ASUS ROG Strix GeForce RTX 4080 SUPER White OC Edition is a graphics card built for 4K gaming and creative workloads. It uses the NVIDIA Ada Lovelace architecture with 16GB of GDDR6X memory on a 256-bit bus. The card runs at a 2670 MHz boost clock in OC mode and 2640 MHz in default mode. It connects via PCI Express 4.0 and supports DirectX 12 Ultimate and OpenGL 4.6.

Triple-slot cooler needs case clearance

Installation follows the standard PCI Express 4.0 slot and requires sufficient power connectors for the digital power control system with 15K capacitors. The 3.5-slot design with a diecast shroud, frame, and backplate adds physical weight and occupies three to four expansion slots. Common issues include inadequate case clearance for the 3.5-slot thickness and insufficient power supply headroom for the high-current power stages.

Suits high-refresh 4K builds not small cases

This card suits enthusiasts targeting high-refresh 4K gaming with DLSS 3 and ray tracing, plus creators needing 7680 x 4320 output across four displays via two HDMI 2.1 and three DisplayPort 1.4a ports. The vapor chamber and Axial-tech fans scaled for 23% more airflow keep thermals in check. Builders with compact chassis or limited PCIe slot spacing should consider a slimmer model.

Questions about this item

How can I confirm the card is running at its intended boost clock after installation?

Use GPU Tweak III to monitor the core frequency; the OC mode target is 2670 MHz and the default mode target is 2640 MHz.

What accessories are included in the box and what must I purchase separately?

The card itself is included; you must supply a compatible power supply with sufficient PCIe power connectors for the 3.5-slot design.

Which version should I choose for 4K gaming on multiple monitors?

The 16GB GDDR6X model with 256-bit interface supports up to four displays at 7680 x 4320 resolution via two HDMI 2.1 and three DisplayPort 1.4a outputs.
