MSI GeForce RTX 5090 Suprim Liquid OC

Manufacturer: MSI

The MSI GeForce RTX 5090 Suprim Liquid OC is a flagship-tier graphics card from MSI, based on NVIDIA's Blackwell architecture and manufactured on a 5nm process node. It features an air-water hybrid cooling solution and RGB lighting, with a physical footprint of 280mm × 148mm. The card delivers a floating-point performance of 108 TFLOPS, supported by a boost clock reaching 2482 MHz under load.

On the memory side, the RTX 5090 Suprim Liquid OC is equipped with 32GB of GDDR7 VRAM across a 512-bit memory bus, yielding a maximum bandwidth of 1790 GB/s at an effective speed of 28000 MHz. The GPU features 21,760 shading units, 680 texture mapping units, and 176 render output units, alongside a pixel rate of 436.8 GPixel/s and a texture rate of 1688 GTexels/s. It supports DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, and Intel Resizable BAR, and connects via PCIe 5.0. Display output is handled through one HDMI 2.1b port and three DisplayPort connections, supporting up to four monitors simultaneously.

Pros
  • The 32GB GDDR7 VRAM across a 512-bit bus delivers a maximum memory bandwidth of 1790 GB/s, which is well-suited for memory-intensive workloads
  • Air-water hybrid cooling is included, helping to manage thermals on a card with a 575W TDP without requiring a separate cooling solution
  • Support for ray tracing and DLSS expands rendering options for compatible applications
  • Up to four displays can be driven simultaneously through a combination of one HDMI 2.1b and three DisplayPort outputs
  • ECC memory support adds a degree of data integrity protection useful for compute-oriented tasks
  • Double Precision Floating Point (DPFP) support broadens the card's applicability beyond typical graphics workloads
Cons
  • A TDP of 575W places significant demands on system power delivery and chassis airflow
  • The card's dimensions of 280mm x 148mm require careful consideration of case compatibility before installation
  • There are no USB-C or DVI outputs, which limits connectivity options for users with displays relying on those interfaces
  • The absence of XeSS (XMX) support restricts upscaling options to DLSS only
Who is this for?

This card is well-matched to users running demanding compute and rendering workloads, where the combination of 108 TFLOPS, Double Precision Floating Point support, and ECC memory makes it a capable choice for tasks that require both graphical output and numerical precision. The 32GB of GDDR7 VRAM with 1790 GB/s of memory bandwidth also suits workflows that involve large datasets or high-resolution assets, such as 3D content creation or simulation. Users who need to run up to four displays simultaneously will find the output configuration — one HDMI 2.1b and three DisplayPort connections — directly accommodating, while the integrated air-water hybrid cooling removes the need to source a separate thermal solution for such a high-TDP card.

Who is this NOT for?

The card's 575W TDP makes it a poor fit for systems with modest power supplies or limited chassis airflow, as inadequate power delivery or cooling infrastructure would compromise stability. Its physical dimensions of 280mm x 148mm may also cause clearance issues in compact or mid-tower cases, making it unsuitable for small form-factor builds. Additionally, users who rely on USB-C or DVI display connections will find the port selection restrictive, and those looking for XeSS upscaling support will need to look elsewhere, as that feature is not present on this card.

It carries a Thermal Design Power (TDP) of 575W and relies on an air-water hybrid cooling solution to manage thermals. The card measures 280mm in width and 148mm in height, giving a clear indication of the physical space required for installation.

Final Verdict

The MSI GeForce RTX 5090 Suprim Liquid OC is a high-specification graphics card built around NVIDIA's Blackwell architecture, bringing together a substantial compute capability, 32GB of GDDR7 VRAM across a 512-bit bus, and an integrated air-water hybrid cooling solution into a single package. Its support for ray tracing, DLSS, ECC memory, and Double Precision Floating Point broadens its relevance beyond conventional rendering tasks, while the four-display output configuration adds practical versatility. That said, its 575W TDP and large physical footprint demand a carefully provisioned system, and the absence of USB-C outputs and XeSS support means it is not without constraints. For users whose workloads and system infrastructure align with what this card requires, it represents a well-equipped option at the upper end of the consumer graphics card segment.
