Introducing the EK-Quantum Reflection³ Uni Distro Plate 300 D5: Universal ATX Distribution Plate with Integrated Bypass Valve

EK by LM TEK has unveiled the EK-Quantum Reflection³ Uni Distro Plate 300 D5, a groundbreaking universal ATX distribution plate designed for custom liquid cooling enthusiasts. This innovative solution combines a 300ml reservoir and a powerful D5 PWM pump, all mounted on a standard 120 mm fan bracket. Its universal compatibility makes it an ideal choice for a wide range of modern ATX PC cases, including popular models like the Lian Li O11D series and ASUS ROG Hyperion GR701.

Universal Compatibility for Modern PC Cases

The EK-Quantum Reflection³ Uni Distro Plate sets itself apart from traditional distribution plates by offering true universal compatibility. It mounts directly onto standard 120 mm fan mounting holes, ensuring seamless integration with a variety of cases. Supported models include:

  • Lian Li O11D
  • Lian Li O11D XL
  • Lian Li O11D EVO
  • Lian Li O11D EVO XL
  • Lian Li O11D EVO RGB
  • ASUS ROG Hyperion GR701

Additional case compatibility will be verified and updated post-launch. The minimum required clearance for installation is 130 x 80.5 x 300 mm.

Industry-First Integrated Bypass Valve for Effortless Maintenance

One of the standout features of the EK-Quantum Reflection³ Uni Distro Plate is its integrated bypass valve, an industry-first innovation that streamlines custom loop maintenance. This valve allows for fast, efficient draining, flushing, and refilling of your liquid cooling loop—no need to disconnect fittings, tilt, or lift your case.

To perform maintenance, simply drain the loop using the EK-Quantum Torque drain valve. Once gravity has removed the bulk of the coolant, close the bypass valve to pressurize the system. Attach an air blower via the G1/4" port or with an STC fitting and soft tube to clear any remaining coolant. Refilling is just as straightforward—open the bypass valve and allow coolant to flow through the loop. This process minimizes mess and simplifies coolant changes, making loop maintenance more accessible than ever.

EK-Matrix7 Standard for Clean, Modular Builds

The EK-Quantum Reflection³ Uni Distro Plate adheres to the EK-Matrix7 standard, ensuring precise port alignment for seamless integration with EK’s Vector² and Vector³ GPU water blocks, active backplates, and Quantum Surface radiators. With G1/4" threaded ports on both the front and rear, users can achieve clean tube routing regardless of chassis layout or radiator placement, reducing planning time and tube bends for a more streamlined build.

High-Performance D5 PWM Pump

This distribution plate is equipped with the latest Generation 3 D5 PWM pump, delivering 30 W of power with minimal noise. Manufactured in Europe, the D5 pump offers PWM control from approximately 20% to 100% duty cycle, enabling precise flow management and quiet operation even in complex, multi-block cooling configurations. The result is reliable, high-performance liquid cooling for demanding PC builds.

Customizable D-RGB Lighting

The EK-Quantum Reflection³ Uni Distro Plate features a full-length addressable D-RGB LED strip with 16 LEDs, elegantly concealed behind an anodized black aluminum cover to prevent LED hotspots. The lighting system is compatible with all major motherboard ARGB sync platforms, including ASUS Aura Sync, MSI Mystic Light, ASRock Polychrome Sync, GIGABYTE RGB Fusion, and Lian Li L-Connect, allowing users to personalize their build’s aesthetics.
