ASUS TUF Gaming RTX 3080 Ti 12GB graphics card

The ASUS TUF Gaming GeForce RTX 3080 Ti is a high-performance GPU built for enthusiasts and creators. It features 12GB of GDDR6X memory on a 384-bit bus with 10240 CUDA cores. Boost clocks reach 1785 MHz in OC mode and 1755 MHz in Gaming mode. It targets 4K gaming and demanding content workloads.

PCIe 4.0 x16 graphics card with 2.7-slot cooler

The card uses a PCI Express 4.0 x16 interface and occupies 2.7 slots in the chassis. It measures 11.81 inches long and 5.00 inches high, so case clearance must be checked. Three DisplayPort 1.4a and two HDMI 2.1 ports drive up to four displays at 7680 x 4320. A robust power supply with sufficient PCIe connectors is required.

Upgrade from RTX 3080 or earlier 10GB cards

Moving to this 12GB model adds 2GB of VRAM and a wider 384-bit memory interface over 10GB 320-bit predecessors. The extra capacity helps with high-resolution textures and large creative datasets. The jump is worthwhile when current VRAM limits cause stutter or prevents max-quality settings at 4K.

Questions about this item

How long is the card and will a 2.7-slot design fit my case?

The card measures 11.81 inches long by 5.00 inches high and occupies 2.7 expansion slots; verify your case clearance and motherboard spacing before purchase.

How loud and hot does the TUF Gaming RTX 3080 Ti run during all-day loads?

Three axial-tech fans on a 2.7-slot heatsink move air through a full-length vapor chamber; expect typical high-end GPU thermals and fan noise that ramps with sustained 1785 MHz boost clocks.

What power connectors does the RTX 3080 Ti need and what PSU should I already have?

The card draws power through multiple 8-pin PCIe connectors on a PCI Express 4.0 x16 interface; ensure your power supply provides enough 8-pin leads and sufficient wattage for a 12 GB GDDR6X flagship GPU.
