Review : MSI RTX 4090 Suprim Liquid X


MSI RTX 4090 Suprim Liquid X:


This MSI RTX 4090 Suprim Liquid X benefits from NVIDIA’s brand new architecture, i.e. “ADA Lovelace”. This architecture replaces the Ampere architecture of the GeForce RTX 30xx launched a little over two years ago.

This flagship model of NVIDIA has a GPU AD102-300 with 16384 CUDA cores. It has 24 GB of GDDR6X memory with a bandwidth of 1 TB/s and it sees its TDP reaching 450 watts. The speed of this RTX 4090 should be 2 to 4 times faster than the RTX 3090 Ti according to NVIDIA. On the next page, we will come back in details on the new features brought by this new architecture, including the support of DLSS 3.

The bundle of this Suprim Liquid X:

So what do we find in this imposing box? As soon as you open it, you can see the presence of a Suprim mouse pad. It is also present in the version with an aircooling system.

There is also an adapter that allows to “split” the 16-pin connector into four 8-pin. However, good news since we have the CORSAIR 12VHPWR 600Wconnector to combine with our Corsair HX1500i power supply. This adapter plugs directly into the power supply on two PCIe slots.


If the “Suprim” series is very well known at MSI, it is the first time that the brand offers a version with a standalone liquid cooling system of type AIO. The combination of such a cooling system with the “Suprim” series should offer us a high-end card with great performance.

The card will embark a liquid cooling system that consists of a waterblock to keep the GPU and memory chips cool but also a 240 mm radiator to dissipate heat. So we are on an AIO type liquid loop, i.e. pre-installed. You receive your copy of the RTX 4090 Suprim Liquid X and you install it directly into your PC.

To optimize this cooling, a TORX 5.0 fan comes to cool a heatsink placed on the power stages of the PCB. It has nine blades that are connected three by three. This fan is inserted via an octagonal cutout in the brushed aluminum cover.

The radiator in charge of keeping the liquid cool has dimensions of 275 x 120 x 25 mm. The two fans associated with it are 120mm MSI Silent Gale P12 models, designed to offer a high airflow with very little noise. If the temperature is cool enough, they will remain at rest and therefore be perfectly silent thanks to the MSI Zero Frozr technology. The power connectors are accessible so you can replace them as you wish.

The PVC pipes in which the liquid will circulate are sheathed to offer a nicer finish. Their length is 40 cm. Finally, you should know that the card has two different BIOS: silent and gaming . We will evaluate the performance of the card based on the gaming, knowing that it is by default that is selected by MSI.

The cooling system :

Let’s take apart the cooling system to see how it is arranged. The first step is to remove the backplate and the brushed aluminum cover. It is actually quite simple. The backplate has a double role, stiffening the PCB but also playing a role of heat dissipation through the pads that are placed between it and the PCB.

The waterblock /pump combo is placed on the graphics chip as well as on the memory chips. An imposing one-piece radiator then has the role of dissipating the heat from the power supply stages via thermal pads. The fan inserted in the casing blows on this radiator and the air is expelled via the support bracket.

The installation of the cooling system is done very cleanly and it is quite easy to disassemble our MSI RTX 4090 Suprim Liquid X.

The connectors:

To power the card, we find the new 16-pin mini-connectors. As we mentioned above, MSI provides in its bund lean adapter to connect four 8-pin connectors.

The card has three DisplayPort 1.4 video outputs and an HDMI 2.1 port.

Yes, some backlighting:

On the front panel, two sides of the octagon have RGB backlighting but also the inscription “Suprim” on the top edge and the logo placed on the backplate,also in brushed aluminum.

As you can see from the pictures above, it’s very discreet and really looks great. The backlighting associated with the brushed aluminum is a real success, personally it is certainly one of the most beautiful graphics cards that I had the chance to have in my hands.
