Review : MSI RTX 4090 Suprim Liquid X


Temperature, power consumption and nuisance:

Weather :

In order to measure temperatures, we opted for the Superposition stress test in Extreme mode. We opted for three 5 minutes runs with 10 minutes interval between each test. We took advantage of this benchmark to measure the power consumption of the graphics card for the table above.

In order to know the temperature in Idle, after having finished the three loops of the stress test, we let the card rest for 20 minutes before reading the temperature. It should be taken into account that most of the cards have the “0 dBa” technology and therefore, the fans turn off below a certain temperature, often between 50 and 55°C. This means that it takes longer to dissipate the heat after a period of stress testing or gaming. A card without this technology will be noisier than others at rest. Small reminder: our temperature readings are taken in Open-Air. In a closed case, the cards will necessarily be hotter.

As we expected, the temperatures are excellent thanks to the liquid cooling system. This cooling should allow us to take full advantage of the overclocking potential, but also to considerably reduce the noise pollution of a solution equipped with 3 fans for example. The fans of the radiator and the one inserted in the casing remain at rest when the temperatures are cool.

Noise level :

No readings for the moment. As we mentioned at the beginning of this article, we have just retested all our maps and unfortunately our test room close to the road, distorts our results. We are looking for a new solution to be perfectly efficient.

Power consumption (full configuration) :

We use a wattmeter by reading the consumption on the output of our power supply. Our modular power supply is a CORSAIR AX1600i. The result we propose is the average of the total consumption of our configuration. Only the graphics card changes between each reading. It is therefore easy to calculate the difference between each graphics card.

We were pleasantly surprised by the power consumption of our MSI RTX 4090 Suprim Liquid X since the average of our total configuration reached 532 watts. Be careful, the benchmark used only solicits the GPU. For a gaming use, the consumption will be more important but that with all our graphic cards.

This result is quite satisfactory and this thanks to the new fineness of engraving. Our RTX 4090 does better than the two top models of the previous generations from AMD and NVIDIA. We should see RTX 4080, 4070 and 4060 doing even better.
