ASUS ROG Strix LC RTX 4090 24GB graphics card

This card pairs the NVIDIA RTX 4090 GPU with 24GB of GDDR6X memory. It targets enthusiasts who need maximum frame rates at 4K and professionals running heavy compute workloads. The liquid-cooled design helps sustain high clocks during extended sessions.

PCI Express 4.0 x16 interface limits

The board connects through a PCI Express 4.0 x16 slot, so bandwidth tops out at the 4.0 specification. Systems limited to PCIe 3.0 will see reduced throughput in data-heavy scenarios. Full performance requires a compatible motherboard and CPU that both support the 4.0 standard.

Liquid cooling and daily implications

The integrated liquid loop moves heat to an external radiator, lowering core temperatures compared with air-cooled equivalents. This allows quieter operation under load but demands case space for the radiator and tubing routing. The card still occupies a standard PCIe slot and provides multiple monitor outputs for multi-display setups.
