Bitspower NEBULA GeForce RTX 5090 ROG ASTRAL

Designed specifically for the ASUS ROG ASTRAL version of NVIDIA's flagship graphics card, the Bitspower Nebula Classic GeForce RTX 5090 ROG ASTRAL water block manages extreme thermal density with a nickel and chromium-plated copper cooling engine. Merging functional precision with the sophisticated "Nebula Classic" aesthetic, this unit features a transparent acrylic housing that displays internal coolant flow while maintaining robust structural integrity for long-term durability.

The full-length base plate covers the GPU die, VRAM modules, and voltage regulators to ensure consistent contact and rapid heat transfer during intense workloads. A Bitspower Digital RGB LED strip is integrated into the top of the block to illuminate the internal structure. The lighting system works seamlessly with major motherboard ecosystems, including ASUS Aura Sync, GIGABYTE RGB Fusion 2.0, MSI Mystic Light Sync, ASRock Polychrome, BIOSTAR VIVID LED DJ, and Razer Chroma for synchronized system-wide effects.

To maintain board stability, a dedicated aluminum backplate is included to reinforce the graphics card PCB and assist in passive cooling for rear-side components. The block arrives with high-performance thermal pads pre-applied to ensure a precise fit and reliable performance from the first power cycle.

Key Features

• Full Coverage Copper Base: A nickel and chromium-plated cold plate extends across the entire card to manage thermal loads over all primary heat sources without obstruction.
• Nebula Classic Design: Thick, clear acrylic housing provides an unobstructed view of the coolant channels and internal construction.
• Integrated Digital RGB Lighting: Addressable LEDs illuminate the block and sync automatically with major motherboard software suites.
• Aluminum Backplate Support: Dedicated backplate improves board stability and dissipates heat from rear-side components.
• Precision Installation: High-performance thermal pads are factory applied for accurate contact during assembly.
