ASUS ROG Strix LC RTX 3090 Ti OC Edition 24GB graphics card

SKU CH-QG5G-9PMEK

Liquid-cooled graphics card with 24GB GDDR6X memory, 240mm radiator, 600mm tubing and PCIe 4.0 interface

  • Memory capacity24 GB
  • Type of memoryGDDR6X
  • Cooling solutionDouble Fans
  • Full-coverage cold plate cools GPU die and memory directly
  • 240 mm radiator balances compatibility and cooling performance
  • 600 mm tubing fits EATX chassis and alternative mounts
  • Blower-style fan and low-profile heatsink cool power-delivery components
  • 24 GB GDDR6X memory enables high-resolution gaming and workloads

Liquid-Cooled RTX 3090 Ti for 4K Gaming

This graphics card pairs a factory-overclocked NVIDIA Ampere GPU with a 240 mm closed-loop cooler. The full-coverage cold plate contacts the die and memory while a blower-style fan handles power-delivery heat. It targets enthusiasts who want sustained boost clocks at 4K resolution without custom-loop complexity.

Suits High-Refresh 4K Builds with 240 mm Mounts

The 24 GB GDDR6X frame buffer and PCIe 4.0 interface feed high-refresh 4K monitors and professional workloads alike. Builders with cases that lack a 240 mm radiator location or 600 mm tubing reach should consider air-cooled alternatives instead.

24 GB GDDR6X Decides 4K Texture Headroom

The 24 GB GDDR6X memory capacity is the single specification that determines whether this card fits the workload. It enables maximum texture quality and large-scene rendering at 4K; any build targeting lower resolutions or smaller VRAM budgets can use a lesser-equipped model.

Questions about this item

Will the 240mm radiator and 600mm tubing fit in a standard mid-tower case?

The 240mm radiator is designed to fit most cases that support a 240mm AIO mount. The 600mm tubing provides extra reach for routing to top, front, or side mounts in larger EATX chassis.

Does the card require a specific power supply or connector type?

The card uses the standard PCIe 4.0 interface and requires sufficient wattage for a 3090 class GPU. Ensure your PSU has the necessary PCIe power connectors for the graphics card itself.

Can the 24GB GDDR6X memory handle 8K gaming workloads?

The 24GB GDDR6X frame buffer combined with 3rd Generation Tensor Cores and DLSS support provides the memory capacity and AI upscaling needed for 8K resolution gaming.
