Hydro Copper waterblock cooling

The EVGA GeForce RTX 3080 Ti FTW3 Ultra Hydro Copper is a high-end graphics card with a factory-integrated copper waterblock. It requires connection to a custom liquid-cooling loop containing a pump, radiator, coolant and tubing to operate. The card carries 12GB of GDDR6X memory across a 384-bit interface with 912GB/s bandwidth.

Suits custom-loop builders only

This model is built for enthusiasts who already maintain a custom watercooling system and want the RTX 3080 Ti core pre-mounted on a full-cover block. Buyers without an existing loop, or who prefer air or all-in-one cooling, should choose a standard FTW3 Ultra model instead. The 1.2-slot width helps dense loop routing.

350 W total power draw

The board pulls up to 350 watts and demands three separate 8-pin or 6+2-pin PCIe power connectors from a minimum 750 W supply. Verifying that your power unit delivers those connectors and sustained wattage is the single specification that determines whether this card will run stably in your loop.

Questions about this item

What custom water-cooling parts must I already have so the Hydro Copper waterblock can function?

You need a complete loop with a pump, radiator, coolant, fans and tubing installed before mounting this card.

Will the PCIe 4.0 interface and 384-bit memory bus work properly on my older PCIe 3.0 motherboard?

The card runs at PCIe 4.0 speeds but is backward compatible with PCIe 3.0 slots, and the 384-bit GDDR6X memory operates independently of the slot generation.

How can I verify the 1800 MHz boost clock and 912 GB/s bandwidth are active after installation?

Open EVGA Precision X1 and watch the real-time GPU clock and memory throughput readings while a 3D load is running.
