ASTRAL LC • 360MM AIO
ROG Astral LC GeForce RTX 5090
Design an enthusiast desktop around liquid cooling and a compact card body. ROG Astral LC pairs RTX 5090 graphics with a separate radiator, letting you plan the GPU and its heat exchanger in different areas of the chassis. This listing is the exact standard-clock 32G-GAMING model.

Engineered for your next build
Integrated card cooling
An Axial-tech fan and low-profile heatsink supplement the radiator.
Premium power delivery
80-amp MOSFETs, GPU Guard and protective PCB coating.
Control and coordination
Dual BIOS, two FanConnect II headers and Aura Sync lighting.
Plan two installation spaces
The slim card body changes where the build needs room, rather than eliminating that requirement. Reserve a suitable radiator mounting location, check its full assembled size and plan a natural tube route. Consider how the GPU radiator shares intake and exhaust paths with the CPU cooler before selecting the chassis.
Build around your display and workload
Choose your processor, display and storage as a complete system. A competitive setup may prioritise responsiveness, while a cinematic game or creative project may call for more visual detail. Begin with settings that suit the applications you actually run; one component alone does not determine the experience.
Establish a comfortable daily setup
Take time to arrange clear airflow paths and accessible cables. A well-planned interior makes installation, inspection and future upgrades easier. Select a lighting effect that suits the desk and coordinate compatible components without obscuring ventilation or making maintenance awkward.
Start with current software
Install up-to-date drivers from official sources. Choose Game Ready drivers for gaming or Studio drivers for supported creative applications. Optional ASUS GPU Tweak III provides monitoring and tuning; begin at default settings, assess temperatures and make deliberate changes rather than assuming an OC setting suits every system.

Specifications follow ASUS’s UK listing for this exact model. Regional availability and included offers may vary. Check current support documentation when configuring your system.
Compatibility & installation
- Check clearance for both the 288.46 × 153.7 × 48mm card and the 400 × 120 × 65mm radiator assembly. A case advertised for 360mm radiators still needs sufficient thickness clearance, tube routing space and compatible mounting positions.
- This is the standard Astral LC 32G-GAMING model. Its optional 2467MHz OC mode does not make it the separately sold O32G OC Edition.
- ASUS’s PSU recommendation is based on an overclocked CPU/GPU configuration. Assess the complete system and confirm cable compatibility; wattage alone does not determine whether a PSU has suitable connectors.
- Five physical display outputs support a maximum of four simultaneous displays. Resolution and refresh-rate combinations depend on monitor, cable and operating mode.
- DLSS and other game features depend on software support and settings. Listed boost and OC-mode clocks are specifications rather than guaranteed sustained frequencies in every workload. Software downloads are separate; regional promotional bundles are subject to their own terms.
Frequently asked questions
Is this the factory OC Edition?
No. The model is ROG-ASTRAL-LC-RTX5090-32G-GAMING, with 2437MHz default boost and a listed 2467MHz optional OC mode.
Do I need to build a custom water loop?
The card uses an included all-in-one liquid cooler. Plan the radiator mounting and follow ASUS’s installation instructions; a separate custom loop is not part of this product.
What radiator space is required?
The official assembled radiator dimensions are 400 × 120 × 65mm. Check actual mounting clearance as well as nominal 360mm radiator support.
What PSU does ASUS recommend?
1000W for the stated system configuration. Evaluate the full PC and compatible 16-pin cabling before assembly.
Can I connect five monitors?
There are five outputs but a maximum of four simultaneous displays. Plan your monitor arrangement accordingly.
