ROG Astral RTX 5090 32GB graphics card

The ASUS ROG Astral GeForce RTX 5090 delivers 32GB of GDDR7 memory on a 512-bit interface for 4K and 8K workloads. A 2580 MHz boost clock and 21760 CUDA cores target enthusiasts and creators who need maximum throughput. The card uses a PCI Express 5.0 connection and occupies 3.8 slots with a triple-fan cooler. White finish suits light-themed builds.

Before ordering check power and space

Your power supply must provide at least 1000W and a single 16-pin connector for the 575W board power limit. The card measures 357.6 mm long so confirm case clearance before purchase. A PCI Express 5.0 slot is required for full bandwidth. Four display outputs (two HDMI 2.1b and three DisplayPort 2.1a) support up to 7680 x 4320 resolution across four monitors.

Sustained load behaviour

The 575W thermal design power means the cooler must dissipate continuous heat during long render or compute sessions. Expect the triple-fan assembly to ramp speeds to maintain the 2580 MHz boost under load. GDDR7 running at 28 Gbps sustains high memory bandwidth without throttling. Power draw stays at the rated limit so PSU headroom remains critical for stability.

Questions about this item

What comes in the box and what do I need to buy separately?

The package includes the triple-fan white graphics card. You must supply a power supply rated at least 1000W and a motherboard with a PCI Express 5.0 slot.

Which capacity should I choose?

This model is offered only with 32GB of GDDR7 on a 512-Bit bus, so there is no alternative capacity to select.

What does the 2580 MHz boost clock mean in my system?

It is the peak GPU frequency the card can reach under load, supported by 21760 CUDA cores and 28 Gbps memory, provided your cooling and 575W power budget are adequate.
