Verdict

The ASUS ROG Strix GeForce RTX 3090 Gaming OC is a high-performance graphics card built on NVIDIA's Ampere architecture, featuring 10,496 CUDA cores and a massive 24GB of GDDR6X VRAM on a 384-bit interface. This factory-overclocked model reaches a boost clock of 1890 MHz in OC mode and features a 2.9-slot cooling system with three Axial-tech fans—where the center fan rotates in reverse to reduce turbulence. Its primary strengths include exceptional 4K and 8K gaming capabilities, a robust 18+4 phase power delivery system, and a high manual power limit of up to 480W for enthusiasts. However, potential drawbacks include its significant physical footprint (318.5 mm length), very high power requirements requiring at least an 850W PSU, and potential for audible coil whine under heavy loads.
