MSI GeForce RTX 4090 SUPRIM Liquid X Closer Look + Teardown

Unlike the massive monstrosities that the air coolers are in, the RTX 4090 SUPRIM Liquid X comes in a very attractive 2-slot design. The card is a semi-hybrid design with a pump that leads to a 240mm AIO radiator and a singular Torx 5.0 fan with axial tech that further helps to dissipate heat. The RTX 4090 SUPRIM Liquid X measures 280x140x43mm while the radiator (with fans installed) measures 274x121x55mm. The whole thing weighs in at just 2353g.

You would have to keep in mind the height when going for a dual-card solution as your case or motherboard PCIe slot combination may not allow such a setup. Since this is a liquid-cooled GPU, the card requires a decent amount of room within the chassis to fit the radiator. I used the Cooler Master C700M which is a full tower casing to check if the cables have enough length to reach the top and front of the chassis. I can confidently say that you won't run into issues with the length of the cable. For reference, they measure 470mm.

The back of the card features a solid backplate that looks stunning. The backplate offers a lot more functionality than just looks which I will get back to in a bit.

The MSI SUPRIM Liquid X design takes the design philosophy of the SUPRIM lineup and further refines it into something elegant. Sure the SUPRIM X is a beast on its own and looks great but the Liquid X is more visually appealing with its more simplistic look.

MSI is using high-quality materials to design the shroud which makes use of an all-aluminum metal cover, angle-beveled edges with a light-gold color polish, and an octagon cut-out for the fan with an illuminated chevron on the back. It is honestly a well-made card.

Coming to the fans, the card actually features the latest fan designs based on the Torx 5.0 system. The singular fan features a ring-based design to allow for higher airflow to be channeled within the main heatsink. The fan deploys a double ball bearing design and can last a long time while operating silently. The fan body has three blades that form three sets and each fan has three sets of them that make up a total of 9 fan blades. Each blade is tilted at a 22 degrees angle to the main high-pressure airflow.

MSI also features its Zero Frozr technology on the Tri Frozr heatsink. This feature won’t spin the fans on the card unless they reach a certain threshold. If you notice closely, you can see that the card features beveled edges that are polished several times with a diamond-tipped cutter to achieve a mirror finish and that can give a slight gold effect which looks great.

In the case of the Tri Frozr heatsink, that limit is set to 60C. If the card is operating under 60C, the fans won’t spin which means no extra noise would be generated.



I am back at talking about the full-coverage, full metal-based backplate that the card uses. The whole plate is made of solid metal with rounded edges that add to the durability of this card. The brushed matte-black finish on the backplate gives a unique aesthetic. The graphics card also comes with a compact PCB design which means that the shroud, heatsink, and backplate are all extended beyond the PCB. The third fan blows air through the heatsink and blows it out from the cutouts that are situated at the very end of the backplate.

There are cutouts in screw placements to easily reach the points on the graphics card. We can also see the new SUPRIM logo which drops the Dragon design and goes for a Diamond shape on the back which looks stunning. MSI says that this is their new SUPRIM logo and is inspired by diamond crystals and geometry to represent the high-quality materials and construction of SUPRIM graphics cards.

MSI is also using heat pads beneath the backplate which offer more cooling to the electrical circuitry on the PCB. The most interesting thing to spot on the back aside from the backplate is the large retention metal bracket which adds more mounting pressure to effectively disperse heat from the GPU to the heatsink.



With the outside of the card done, I will now start taking a glance at what's beneath the hood of the SUPRIM Liquid X. Unlike the SUPRIM X, the Liquid X is a dual-slot design and as such, it doesn't use a huge aluminum fin block. It is also a liquid-cooled variant and as such, it has a fully enclosed body with just two tubes leading into the central chamber.

Underneath the shroud is the latest pump that MSI will be using with their SUPRIM Liquid X coolers.

The pump makes use of a micro-fin copper base which has a large central GPU contact surface and four exterior arms with a thicker surface to make direct contact with the 12 memory modules that are featured on the RTX 4090. Each arm has thermal pads featured on it to make sure that the heat is dissipated effectively.

The whole build quality of the copper block looks great and should be enough to handle the 530W power limit that the card reaches its max.


MSI adds extra protection to its impressive PCB by including a rugged anti-bending plate. This also acts as additional memory and MOSFET cooling plate while the PWM heatsink with micro fins keeps the VRM cool under stressful conditions. The 240mm radiator comes with MSI's latest MEG Silent GALE P12 fans which I have already tested with MSI's MEG S360 Liquid cooler and they are some of the quietest fans in the market right now.

I/O on the graphics card sticks with the reference scheme which includes three Display Port 1.4a & a single HDMI 2.1 port.

There's also a dual-BIOS switch on the card which comes pre-configured with Silent & Gaming modes. The BIOS doesn't affect the clock profiles but rather affects the maximum power limit, enabling higher fan speeds for better cooling and more stable clocks. The limits are 450W for the silent and 480W (with 530W Power Limit) for the gaming profile.

MSI GeForce RTX 4090 SUPRIM Liquid X Teardown:

MSI makes use of a 26+2 phase PWM design that is made up of high-quality components such as  HCI or High-Efficiency Carbony Inductors, SPS (Smart Power Stages), and hardened defense fuse.




The card also uses the latest GDDR6X DRAM from Micron which operates at 21.0 Gbps alongside a 384-bit wide memory interface.



The MSI GeForce RTX 4090 SUPRIM Liquid X is a very power-hungry graphics card as showcased by its custom design. Being so, the card utilizes a single 16-pin connector which can deliver up to 600Watts of power to the graphics card. The card is rated at 480W but ends up around 530W with its full power limit.


MSI GeForce RTX 4090 SUPRIM Liquid X Mystic RGB Lighting Gallery:

MSI SUPRIM X series cards utilize their Mystic Light RGB technology to offer you a visually pleasing lighting experience on your graphics cards.


There are a total of 5 different RGB effects that you can choose from and the cards have 3 RGB accent points on the front, one on the back, and one lightbar surrounding the side of the card which looks really good. You can fully customize the RGB lights to your preference using the MSI Mystic Light application from MSI's web page. Following is what the graphics card looks like when lit up.
