Be the first to review this product...
  • FITS THE LISTED CARDS: Full-coverage block with aluminum backplate for the cards listed under Compatibility. It is matched to those circuit boards only, so confirm your exact model first.
  • WHOLE-CARD COOLING: One cold plate covers the GPU chip, the memory and the power stages in one pass. The base is T2 copper with electroless nickel plating under a clear acrylic top.
  • 5V ARGB LIGHTING: The block has built-in 5V addressable RGB lighting to match the rest of your build. It connects to a 5V 3-pin ARGB header on the motherboard or to an ARGB controller.
  • QUIET AND ON SHOW: Swapping the stock cooler for this block removes its fans, so the card runs quieter under load. The nickel-plated copper and acrylic top stay on display in a visible loop.
  • USA SUPPORT, FRIENDLY AND EXPERIENCED: Tyler Direct provides knowledgeable US-based support for troubleshooting and compatibility questions. Every purchase carries a 1-year warranty covering defects.

The Bykski N-AS5090ASTRAL-X-V2 is a full-cover GPU water block with a matching aluminum backplate for PC builders adding a flagship graphics card to a custom liquid cooling loop. It fits the ASUS ROG Astral Gaming GeForce RTX 5090 32GB OC and the other cards it fits, including the ASUS ROG Astral LC Gaming GeForce RTX 5090 32GB and the ASUS ROG Astral Gaming GeForce RTX 5090D 32GB. One nickel-plated copper cold plate takes heat from the whole card so your radiators can carry it away.

Why it works

  • One cold plate covers the GPU chip, the memory and the power stages in one pass.
  • 56 micro-channels spread heat over a wide area for steady temperatures in long sessions.
  • T2 copper base with electroless nickel plating and a clear acrylic top.
  • No stock fans, so the card runs quieter under load.

Specifications

  • Block Material: Nickel-plated T2 copper, acrylic top
  • Backplate Material: Aluminum (not in contact with coolant)
  • Dimensions: 260.78 x 162.7 x 26.57 mm
  • Port Thread: G1/4

In the box

  • GPU water block with backplate: 1
  • 1.5 mm thermal pads
  • Thermal paste: 1
  • Backplate screw

Installation

  • Remove the stock cooler from the card and clean the old thermal material from the GPU chip, the memory and the power stages.
  • Apply the included 1.
  • Set the water block on the card, then mount the backplate with the included backplate screws.
  • Install the card in the PC and connect the block's G1/4 ports to your loop with your fittings.
  • Connect the block's ARGB lighting cable.
  • Fill the loop and check every joint for leaks.

Warnings

Never power the card without the loop installed and the pump running.

Thermal pads go where the block has raised contact points; the GPU chip takes thermal paste.

Tighten the block's screws evenly and finger tight; over-tightening can crack the acrylic top.

The lighting plugs into a 5V 3-pin addressable (ARGB) header or an ARGB controller only. A 12V 4-pin RGB header will damage it.

No printed instructions are included; the installation illustration is in the product images.
