The air-cooled RTX 5090 SUPRIM X has already proven in my test that even 600 watts of GPU power can be tamed surprisingly quietly as long as there is enough cooling surface and a well thought-out design. But even the best air cooling concept has a decisive catch: the heat remains in the housing. And if a graphics card produces more waste heat than a good-natured fan heater, even the best case layout can quickly mutate into a circulating air grill station. This is precisely where MSI’s SUPRIM LIQUID X comes in. With a 360 mm radiator, relocated waste heat source and AiO circuit, the thermal load is specifically shifted to where it won’t cause any damage – ideally directly out of the case. This keeps the CPU cool, the mainboard breathes a sigh of relief and the RAM doesn’t feel like it’s in a Finnish dry sauna.

In this review, I take a look at whether reaching for the hose brings more than just visual progress. For all those who are not yet familiar with the air-cooled version: There’s a separate article on this too, which shows how far you can actually get with a conventional cooler. And if you’re still on the fence, you’ve probably never questioned the thermal concept of an oven.

The MSI RTX 5090 SUPRIM SOC LIQUID 32GB

If you spend a good 2700 euros on a graphics card, then you can expect not only the performance to be right, but also the overall package to be convincing: clock rates, cooling, build quality and yes, an unboxing experience that is commensurate with the price. The MSI RTX 5090 SUPRIM LIQUID SOC is in this league, and in my review I mentally place it next to the air-cooled version I have already tested in order to illustrate the advantages of the integrated AiO water cooling.

From the first glance at the assembled card and radiator, it is clear that this graphics card is not just another air-cooled model with a stick-on logo, but a purposefully designed high-end product aimed at users who do not want to compromise on performance and cooling. The RTX 5090 SUPRIM LIQUID X relies on a factory-installed 360 mm AiO water cooling system whose hoses are firmly connected to the GPU’s cooling block. This makes it not only the longest graphics card, but also the widest cooling unit in this class – if the radiator and hoses are included.

The graphics card itself measures around 280 mm in length, is 148 mm high and remains comparatively compact with 2 slots if you only look at the actual PCB. The massive cooling block on the GPU with integrated pump and a single axial fan, which presumably actively ventilates the VRMs and memory on the card, is striking. The housing is made entirely of brushed aluminum, which gives the card a cool, industrially elegant appearance. The “SUPRIM” lettering on the front surface is discreetly lasered in, as is the geometrically shaped fan window on the right. The finish is of a very high quality. All visible parts are metallic or made of high-quality, matt plastic. The hoses are textile-coated and appear robust without being unnecessarily stiff. The pump on the GPU is centered under the fan, with a clearly defined structure and no unnecessary RGB flood.

The backplate is also made of brushed aluminum with a two-part finish. The silent/gaming BIOS switch is recessed at the top and easily accessible. The backplate is secured with additional screws and also serves as a passive heat dissipation surface for rear memory or voltage converters. Depending on the model, the recessed SUPRIM logo also functions as an RGB-illuminated element, as does the MSI logo on the front of the card. The hoses lead out of the side of the cooler and are laid with a generous bending radius to ensure the most flexible installation possible in the housing. The entire solution is visibly modular, but is pre-assembled at the factory and cannot be serviced.

The supplied radiator is a 360 mm model with three pre-installed 120 mm axial fans. The design is also retained throughout: black fan frames with silver MSI centerpiece, structured fan blades and a solid aluminum heat sink. The radiator height is approx. 27 mm, the fans are 25 mm. All cables are sleeved and the connections are neatly combined. RGB signals and fan control are carried out via separate headers so that synchronous control via the mainboard or MSI software is possible.

The SUPRIM logo is once again clearly highlighted on the top under a translucent plastic insert, which is backlit by RGB LEDs. The power connection is also visible: a single 16-pin 12V 2×6 connector, which is located in the middle of the card and is led out at the top. The integrated VRM module and the contact surface for the voltage converter cooling can be seen directly next to it. The top edge is complemented by a finely milled GeForce RTX engraving, also in a brushed aluminum look. The hoses are routed upwards at the outermost edge and appear well decoupled.

The MSI RTX 5090 SUPRIM SOC is equipped with a selection of modern display outputs that ensure a high level of compatibility with current monitors and displays. Specifically, the graphics card has three DisplayPort 2.1b ports and one HDMI 2.1b port. This configuration enables the simultaneous operation of up to four displays. The DisplayPort 2.1b connections support resolutions of up to 8K at 165 Hz or 4K at 480 Hz, while the HDMI 2.1b connection enables resolutions of up to 8K at 60 Hz or 4K at 120 Hz. These versatile connectivity options ensure a flexible and powerful connection to different display setups.

The RTX 5090 SUPRIM LIQUID X shows where the journey is headed right out of the box. From the design to the cooling to the choice of materials, MSI makes no secret of the fact that this card is aimed at enthusiasts who consciously focus on clear heat management, high performance reserves and a tidy aesthetic. The AiO water cooling does not look like an afterthought, but rather an integral part of the overall cooling concept. If you are looking for a GPU that does not distribute the heat in the housing but dissipates it in a targeted manner, you will find it here. And anyone who has ever held the assembly in their hands will know that there has been no spillover here, but rather that it has been laid ex works. The card also finally offers a dual BIOS, which can be switched between a performance-oriented mode and a low-noise mode.

This allows the user to flexibly adapt the graphics card to the respective requirements. I even measured this separately. The silent option on the left and the gaming option on the right:

The technical details and manufacturing of the MSI RTX 5090 SUPRIM LIQUID SOC focus on high computing power, efficient cooling and a stable design. The rest corresponds to the article on the air-cooled card, so I’ll save the redundancy for now.
