ASUS ROG Astral GeForce RTX 5090 32GB

The ASUS ROG Astral GeForce RTX 5090 32GB is a graphics card built for 4K gaming and professional rendering workloads. It uses the NVIDIA GeForce RTX 5090 GPU with 21760 CUDA cores and a 512-bit memory interface. The 32GB GDDR7 frame buffer runs at an effective 28000 MHz clock. The board connects through a PCI Express 5.0 slot.

Thermals noise and power draw in normal use

The card operates at a game clock of 2610 MHz and a boost clock of 2580 MHz under typical load. Power consumption scales with the 5090 chipset design and the 28 Gbps memory speed. Fan curves respond to GPU temperature targets set in the driver. Acoustic output varies with the thermal profile selected in the companion software.

DLSS 4.0 and display connectivity

DLSS 4.0 upscaling and frame generation accelerate supported titles at 7680 x 4320 resolution. The output panel provides two native HDMI 2.1b ports and three native DisplayPort 2.1a connectors. Multi-monitor support extends to four simultaneous displays. OpenGL 4.6 compatibility covers legacy professional applications.

Questions about this item

Will this card physically fit in my case and what power connectors does it need?

The card uses a PCI Express 5.0 interface and requires a case with enough length and height clearance for a triple-slot design. You will need a power supply with native 12VHPWR or three 8-pin PCIe cables for the adapter.

Can I run four 4K monitors at high refresh rates with the provided video outputs?

Yes, the card offers two HDMI 2.1b and three DisplayPort 2.1a ports, supporting up to four displays at a maximum resolution of 7680 x 4320.

What does the 32 GB GDDR7 memory and 21760 CUDA cores mean for 4K gaming and creative work?

The 32 GB frame buffer and 512-bit bus at 28 Gbps give headroom for 4K textures and large 3D scenes, while 21760 CUDA cores accelerate rasterisation, ray tracing and DLSS 4.0 frame generation.
