Liquid-cooled Radeon RX 6900 XT for 4K gaming

This ASUS ROG Strix card pairs the AMD Radeon RX 6900 XT GPU with a hybrid cooler that uses a full-coverage cold plate and a 240 mm radiator. Sixteen gigabytes of GDDR6 memory on a 256-bit bus feed 5120 stream processors at a 2525 MHz boost clock. The PCIe 4.0 interface and VR-ready HDMI 2.1 plus two DisplayPort 1.4a outputs drive up to four displays at 7680 x 4320.

Sustained-load behaviour with hybrid cooling

Under continuous load the liquid loop moves heat from the GPU die and memory to the radiator, while a blower-style fan and low-profile heatsink cool the power-delivery components. The 600 mm tubing allows flexible radiator placement in EATX chassis, helping the card hold higher clocks longer than an air-only design would. CrossFire support for DirectX 12 and Vulkan remains available for multi-GPU compute workloads.

Compatibility checklist before ordering

Verify that your power supply meets the 850 W recommendation and provides three 8-pin connectors. Ensure the case can mount a 240 mm radiator with 600 mm tubing clearance for the chosen orientation. Confirm the motherboard has a PCIe 4.0 x16 slot and that HDCP 2.3 support is present for protected 4K content.

Questions about this item

How loud and hot does the hybrid cooler with its 240mm radiator get when the card runs at 2525 MHz all day?

The full-coverage cold plate cools the GPU die and memory with liquid while a blower-style fan handles the power delivery; the 240mm radiator and 600mm tubing are sized to keep temperatures and noise low under sustained load.

My PSU only has two 8-pin cables — will this card work?

No, the board requires three 8-pin power connectors and ASUS recommends an 850W supply, so you need a PSU with at least three 8-pin leads and that wattage headroom.

Will the PCI Express 4.0 interface slow down if I keep my older PCIe 3.0 motherboard?

The card is backward compatible and will run at PCIe 3.0 speeds on a 3.0 slot; real-world gaming impact is usually small because the 256-bit GDDR6 memory and 5120 stream processors handle most workloads on-board.
