NVIDIA GEFORECECE RTX 5090 power cord can also be used.

NVIDIA GeForce RTX 5090 is unquestionable in terms of performance, but it is also a terrible electric power monster. The TDP power consumption has reached 575 W. Under the 12V-2X6 wire, 4 8 PIN PCIE power cables are required to meet power supply, but However, some foreign media have found that if only 3 are inserted, the graphics card can operate normally, and the loss of power consumption is not too high.

When testing the RTX 5090 frequency reduction and power consumption, it was found that whether it is the Asus ROG GeForce RTX 5090 Astral or Zotac GeForce RTX 5090 Solid, it can be turned on normally without connecting only 3 8 Pin PCIe cables. With operation, but if you cut it down, there will be no response.

Since each 8 Pin PCIe power cable can only supply 150 W of power, 3 wires can provide 450 W, which is much lower than the NVDIA preset 575 W and peak 600 W, even if it can be used normally, the performance is destined to be The damage is just a matter of how much it is.

Unexpectedly, according to the actual measurement, if the RTX 5090 power consumption is locked at 450 W, test “Black Myth: Goku”, “Metropolitan Moment: Black Action 6”, “Dark Dragon Age: Guardian Guardian” with 4K resolution The average performance of more than ten games, the loss of efficiency was only 5 %, which was 14 %compared to the RTX 4090 under the same conditions.

What’s more, even if it is further reduced to 400 W and the loss of performance reaches 10%, it is still 9% higher than the RTX 4090 with 450 W power consumption.

Judging from the test results, perhaps the RTX 5090 did not have the power consumption in the original design. It was just to pursue better performance and was overtaken hard.

At the same time, for users, if the power supply is not enough, there is not enough PCIE cables, it can be slightly reduced to the configuration, but for the service life and safety of the product, it is not recommended to do this for a long time.
