Temperature, consumption and nuisance:

Temperature :

In order to measure the 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 impressive cooling system. This cooling should allow us to take full advantage of the overclocking potential but also to reduce noise pollution considerably. The fans of our MSI RTX 4080 Suprim X remain idle when temperatures are cool.

Power consumption (full configuration) :

We use a wattmeter by reading the power 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 overall power consumption of our configuration equipped with our MSI RTX 4080 Suprim X, since the average power consumption of our PC reached 402 watts. Please note that the benchmark used only solicits the GPU. For a gaming use, the global consumption of our configuration will be more important but that with all our graphic cards.

This result is an excellent surprise and is related to the new fineness of the engraving. Our RTX 4080 does better than the RTX 3080 Ti FE. As soon as we get our hands on the PCAT tool or the new version of the ElmorLabs PMD Power Measurement Device supporting 12+4 pins, we will update this graph by isolating only the graphics card.
