ASUS TUF-RTX5090-O32G-GAMING graphics card

32GB GDDR7 frame buffer

The ASUS TUF-RTX5090-O32G-GAMING is a GeForce RTX 5090 graphics card built on the Blackwell architecture with 32GB of GDDR7 memory across a 512-bit interface. It targets 4K and 8K gaming workloads as well as compute tasks that benefit from high memory bandwidth. The card delivers 21760 CUDA cores with a game clock of 2580 MHz and a boost clock of 2550 MHz. It connects through a PCI Express 5.0 x16 slot.

PCI Express 5.0 x16 slot requirement

Installation requires a motherboard with a PCI Express 5.0 x16 slot and a chassis that can accommodate a 348 mm long, 3.6-slot thick ATX form factor card. The board draws up to 575W, so a 1000W power supply is recommended to keep the rest of the system stable. Three DisplayPort 2.1b and two HDMI 2.1b outputs drive up to four displays at 7680 x 4320 resolution. The triple-fan cooler exhausts heat into the case, so adequate case airflow is necessary.

575W thermal design power

Under sustained load the GPU operates within a 575W thermal design power envelope, and the triple-fan cooler is sized to dissipate that heat continuously rather than only in short bursts. The 28 Gbps GDDR7 memory maintains its 28000 MHz effective clock during extended sessions, preserving bandwidth for ray tracing and DLSS 4.0 upscaling. DirectX 12 Ultimate and OpenGL 4.6 support remain stable across long render or compute jobs. The card’s 3.6-slot width means it occupies significant space, so thermal headroom depends on the surrounding case ventilation.
