The EK-Quantum Vector³ Suprim RTX 5090 – Plexi represents the pinnacle of high-performance liquid cooling, designed specifically for the MSI GeForce RTX™ 5090 32G SUPRIM SOC and MSI GeForce RTX™ 5090 32G SUPRIM OC. Featuring an improved, larger cooling engine, higher-performance thermal pads, and a new gasket design to optimize reliability and aesthetics, this water block ensures exceptional cooling efficiency, even under extreme workloads.
The revised cooling structure of the Vector³ Suprim RTX 5090 maximizes heat transfer with an expanded fin array and optimized coolant flow paths. It actively cools the GPU core, VRAM, power stages, and passively cools PCB hotspots through the included backplate.
Built with high-quality components for durability and peak performance:
The Vector³ Suprim RTX 5090 comes with next-gen thermal pads that are partially pre-cut for seamless installation and optimized contact, allowing for superior heat dissipation from VRAM and power delivery components.
Every Vector³ Suprim RTX 5090 water block includes a backplate, designed to:
This L-shaped backplate profile seamlessly encloses the GPU for a clean, unified aesthetic while adding an additional layer of cooling performance.
The EK-Quantum Vector³ Suprim RTX 5090 follows EK-Matrix7, a standard that simplifies liquid cooling loop assembly by aligning ports and spacing components for intuitive tube routing.
Whether mounting the GPU vertically or horizontally, Matrix7 ensures a hassle-free, precise build.
Addressable D-RGB LED lighting is deployed on the longest edge of both top and backside water blocks for improved uniformity and brightness. The PCB and diodes are concealed inside a clean aluminum extrusion. The individually addressable RGB LED is compatible with popular RGB sync technologies from all major motherboard manufacturers. The arrow marking on the 3-pin D-RGB LED connector is to be aligned with the +5V marking on the D-RGB (addressable) header (Pinout: +5V | Data | Blocked | Ground).
Technical Specifications:
Alphacools's fittings go new ways in looks, quality of manufacturing, colours and choice. The inner diameter of these fittings truly deserves the „high flow“ attribute!
The first three colours, Chrome, Deep Black and Shiny Copper offer something for every taste. The product matching series are designed to look elegant in every system, highlighting the individual design of the computer. The limits are endless with these Alphacool fittings in combination with Alphacool tubing!
With a new process during chromatising the surface finish is completely connected with the brass body, hence ensuring permanent intense colours and peeling of the chrome layer. The Alphacool name in blue lettering on some of the fittings additionally underlines the individuality of these items.
Functionality of this connector:
This fitting can be used to connect 13/10mm tubing with a G1/4“ connection thread. The fitting is angled by 45° and is revolvable, allowing easy hose routing in the system.
