White-edition build and 3.5-slot cooler

The card ships in an all-white colourway with a die-cast shroud, frame and backplate that add rigidity and vented surfaces for airflow. Three enlarged axial fans move 23% more air volume than the previous design while a patented uniform thermal plate with milled grooves contacts the GPU directly. The 3.5-slot thickness accommodates the large fin stack required by the 4080 GPU.

PCIe 4.0 interface and modern display outputs

Connection to the host uses a PCI Express 4.0 x16 slot and a single 16-pin power connector fed by a 750 W supply. Video output consists of two HDMI 2.1a ports and three DisplayPort 1.4a connectors supporting up to 7680 x 4320 resolution across four simultaneous monitors. HDCP 2.3 is included for protected content playback.

Thermals, acoustics and power envelope

In normal gaming loads the enlarged fans and uniform thermal plate keep the GPU at the rated boost clocks of 2655 MHz in OC mode or 2625 MHz in default mode without excessive noise. The 256-bit GDDR6X memory running at 22.4 Gbps stays within the 750 W system power recommendation. ARGB lighting syncs with Aura Sync for coordinated system aesthetics.

Questions about this item

What bandwidth does the PCIe 4.0 interface actually deliver to the GPU?

PCIe 4.0 x16 provides up to 32 GB/s of theoretical bandwidth, which is the ceiling for data moving between this RTX 4080 and the rest of the system.

How much case space do the 357.6 mm length and 3.5-slot thickness require?

The card measures 357.6 mm long, 149.3 mm tall and 70.1 mm thick, so your case must clear at least that length and three-and-a-half expansion slots.

Which way does the 16-pin power connector face, and what clearance mistake do builders make?

The single 16-pin connector plugs into the card's front edge; many builders forget to leave room for the cable bend and end up kinking it against the side panel.
