ASUS ROG Astral LC RTX 5090 OC 32GB GDDR7 Graphics Card

The ASUS ROG Astral LC GeForce RTX 5090 OC Edition is a flagship graphics card built for enthusiast gaming, real-time ray tracing, and AI-accelerated workloads. Powered by NVIDIA’s GeForce RTX 5090 GPU with 21,760 CUDA cores, it operates at a boost clock of 2,610 MHz in OC mode and 2,580 MHz in Default mode, delivering substantial compute headroom for demanding titles and creative applications. Cooling is handled by an integrated 360mm AIO liquid cooler featuring a 360 x 38 mm radiator paired with three high-performance fans and a full-coverage copper cold plate. This design transfers heat away from the GPU die efficiently, supporting sustained performance during extended sessions. A low-profile heatsink and axial-tech integrated fan supplement the liquid cooling loop, while a protective PCB coating guards against moisture and debris. On the power delivery side, 80-amp MOSFETs provide the current capacity needed for high-frequency overclocking scenarios. ASUS recommends a minimum 1,000W power supply, with the card drawing power through a single 16-pin connector. Memory configuration consists of 32 GB of GDDR7 running at 28 Gbps across a 512-bit interface, yielding substantial bandwidth for 4K and 8K workloads. The card supports resolutions up to 7,680 × 4,320 and can drive up to four displays simultaneously via its HDMI and DisplayPort outputs. Software support includes ASUS GPU Tweak III for clock, voltage, and fan curve adjustments. NVIDIA platform features include fifth-generation Tensor Cores with FP4 precision for DLSS 4 Multi Frame Generation, fourth-generation Ray Tracing Cores optimised for complex geometry, and new Streaming Multiprocessors tuned for neural shaders. DirectX 12 Ultimate and OpenGL 4.6 are supported.
