EVGA GeForce RTX 3080 Ti XC3 Ultra Hydro Copper graphics card

SKU CH-GW00-8Q6YA

Factory-fitted full-cover waterblock cools the 10240 CUDA core RTX 3080 Ti with 12 GB GDDR6X on a 384-bit bus

  • Memory TypeGDDR6X
  • 10240 CUDA cores deliver high compute throughput
  • 12 GB GDDR6X at 19000 MHz provides 912 GB/s bandwidth
  • 1725 MHz boost clock sustains performance in heavy workloads
  • Full-cover Hydro Copper waterblock enables custom-loop cooling
  • Pre-installed metal backplate with ARGB LED adds rigidity and lighting

Built for Custom Water Cooling

The EVGA GeForce RTX 3080 Ti XC3 Ultra Hydro Copper is a graphics card designed for custom liquid-cooling loops. It ships with a pre-installed all-metal backplate and an integrated waterblock. The card requires a separate pump, radiator, coolant and tubing to operate. It targets enthusiasts building high-performance desktop systems.

Suits Loop Builders Only

This product fits builders who already run or plan a custom open-loop cooling setup. The Hydro Copper waterblock replaces standard air cooling entirely. Buyers without a loop infrastructure should look at air-cooled or all-in-one liquid models instead. A 750 W power supply and two 8-pin or 6+2-pin PCIe connectors are required.

12 GB GDDR6X on 384-bit Bus

The frame buffer provides 12288 MB of GDDR6X memory across a 384-bit interface. Effective clock reaches 19000 MHz for 912 GB/s bandwidth. This capacity and bandwidth combination determines 4K gaming headroom and compute throughput for the 10240 CUDA cores.

Questions about this item

Will the 1.2-slot width and 262.8 mm length fit my case and water-cooling loop?

The card occupies 1.2 slots and measures 262.8 mm long, so verify your case clearance and loop tubing routing before purchase.

How do I connect the two 8-pin or 6+2-pin PCIe power dongles without daisy-chaining?

Run two separate cables from a 750 W power supply directly to the card's power connectors; do not use a single split cable.

When should I plan to replace the coolant in the Hydro Copper waterblock?

Follow your loop manufacturer's schedule — typically every 12 to 24 months — and inspect the block for corrosion or particulate buildup during each change.
