EVGA GeForce RTX 3090 XC3 Ultra Hydro Copper Gaming graphics card

Built for custom-loop cooling

The EVGA GeForce RTX 3090 XC3 Ultra Hydro Copper is a full-cover waterblock graphics card that must be installed inside a custom liquid-cooling loop with pump, radiator, coolant, fans and tubing. It delivers 10496 CUDA cores, a 1725 MHz boost clock and 24 GB of GDDR6X memory on a 384-bit bus for 936 GB/s bandwidth. The card occupies 1.2 slots and measures 262.8 mm long by 132.1 mm high.

Suited for builders with existing loops

This model suits enthusiasts who already maintain a custom watercooling system and want factory-installed hydro-copper cooling with ARGB lighting and an all-metal backplate. It requires a minimum 750 W power supply and two 8-pin or 6+2-pin PCIe power connectors, so systems without adequate power delivery or without a loop should consider air-cooled alternatives.

Sustained load on water

With the GPU die and memory directly coupled to the copper cold plate, heat moves into the coolant continuously rather than saturating a heatsink during short bursts. The 350 W total power draw stays manageable as long as the loop’s radiator capacity and flow rate are sized for that thermal load, letting the 1725 MHz boost hold through extended compute or rendering sessions.
