How does the LC version differ from the air-cooled ROG Astral?

The LC adds a 400 mm radiator and quad-fan hybrid loop instead of an all-air heatsink. That should mean lower GPU temperatures and steadier boost clocks under long loads, at the cost of radiator space and extra tubing in the case.

The card itself is 288.46 x 153.7 x 48 mm and takes 2.5 slots. You also need room for a 400 x 120 x 65 mm radiator, so check both card clearance and radiator mounting before buying.

What power supply do I need?

The card can draw up to 800 W when both power inputs are connected through a BTF motherboard and a 12V-2x6 cable. Plan on a high-wattage ATX 3.x unit with a native 12V-2x6 connector.

You get the card, a detachable AMOLED display, a detachable glass backplate, a detachable GC-HPWR adapter, an ROG Edition 20 graphics card holder, a velcro hook-and-loop strap and an ROG magnet.

Is the AMOLED display required?

No. It is a detachable panel that shows 3D visuals, custom content and real-time hardware data. You can run the card without it if you prefer a plain shroud.

Does it support 8K output?

Yes. Maximum resolution is 7680 x 4320, and there are three native DisplayPort 2.1b outputs plus support for up to four displays.

About the ASUS ROG Astral LC GeForce RTX 5090

The ASUS ROG Astral LC is a liquid-cooled graphics card powered by the NVIDIA Blackwell architecture and DLSS 4.5. It is a GeForce RTX 5090 with 21760 CUDA cores and 28 Gbps memory. It connects through PCI Express 5.0.

A curved AMOLED display shows dynamic 3D visuals, custom content and real-time hardware data. A transparent glass backplate with ROG accents keeps dust out and shows off the GPU's engineering. A detachable GC-HPWR adapter makes the card compatible with standard and BTF motherboards.

Cooling uses a quad-fan design that raises air flow and pressure by 20%. Liquid metal thermal compound cools the GPU more efficiently and allows a higher boost clock. A patented vapor chamber and heat pipes improve heat dissipation and lower GPU temperatures by more than 5%.
