I9-13900K+RTX 4080 Super tries its best to "double repair", how big is the power supply insurance?

Increase the volume without increasing the price, which means that it was newly launched at the beginning of this year RTX 40 SUPER series graphics cards, especially the most high-end RTX 4080 SUPER, are even more than 1000 yuan cheaper than last year's RTX 4080. Although the price is high, the cost performance ratio is also the highest Intel The 13th generation Core i9 is a golden combination, which has become the choice of many high-end players.

However, these two high-energy accessories are also two electric tigers. For example, the full load power of the RTX 4080 SUPER is up to 320W, while the full load power consumption of the Core i9-13900K also reaches about 320-330W. What will the actual operation situation be? On the basis of these two basic accessories Hangjia MVP P1200 Power Supply To carry out a "double repair" high-voltage test.

The test content is also very simple, CPU usage AIDA64 For the overfrequency pressure test in, the test item is the commonly used Stress FPU, which is commonly known as "single baking". This test will leave the CPU in a full load state, while pressing the Core i9-14900K requires high-performance Water cooling radiator Here, Hangjia Poseidon MVP V360 is selected.

In order to ensure better heat dissipation effect, we have selected Hangjia's latest Apollo Max master version of the chassis. This chassis retains the classic left and right independent bin design, with the main accessories and power supply radiating independently. It also has up to 10 fan positions and supports 360mm water cooling radiator The column free design also allows players to create a real "sea view room".

When the Stress FPU is turned on for "single baking", the Core i9-14900K is basically fully loaded, and the radiator cold exhaust fan also turns on the rampage mode CPU temperature Basically constant at 88 ℃.

The RTX 4080 SUPER graphics card is fully loaded, and more than 98% TDP can be achieved by selecting 1080P mode in the commonly known "doughnut" FurMark. At this time, the fan of the graphics card also turns on the rampage mode.

However, a bug will appear in this "double repair" limit test: after opening the "doughnut" FurMark, the CPU temperature will further increase, even reaching 96 ℃. So remember to turn on the air conditioner when doing similar tests. Next, we carried out a 24-hour continuous pressure test. During this period, the host did not appear downtime, restart, black screen, and stuck. The operation was very stable, which showed that the power of Hangjia MVP P1200 power supply was more than enough, and the water-cooled radiator of Hangjia Posen MVP V360 was also powerful.

In terms of the power consumption of the whole machine, the power meter display basically fluctuates around 640W. Although this extreme full load situation is unlikely to be encountered, it is not recommended to use 650W power supply at any risk.

After our limit test, we revealed the actual power consumption of RTX 4080 SUPER, and also proved that such a high-energy configuration, power supply of more than 750W is really reassuring. Have you got it?
