Well, New Nvidia RTX 5090 users must be aware of the cables they use, because not having the right ones could lead to a drop in “notable” performance.
The first consumers must be aware of the power adapters used on NVIDIA RTX 5090 SKU, 4x 8 -pin connectors are a must
This message will serve as a precautionary measure for many flagship users of Nvidia RTX Blackwell, because it seems that not using the right power adapter could hold your respective SKU in terms of performance. Although this is a fairly standard concept, Computer In fact tested GeForce RTX 5090 from NVIDIA on 3x 8 -pin and 4x 8 -pins adapters to see how the drop in power figures leads to a degradation of performance. Interestingly, the supply of 100 W of power less than the optimal number leads to approximately a 5% drop in raised tests.


The GPU was tested on 575W, 450W and 400W TDPS, and it seems that limiting the power supply makes a notable difference, although this is indeed obvious. The interesting part here is that the SKU was functional with a connection to three pins, but the source indicates that the GPU did not work on 2x to 8 -pin connectors, which means that the exploitation of the GeForce RTX 5090 on 300W is no longer an option.


By having 8 -pin 8 -pin power connectors on board, you provide NVIDIA RTX 5090 with a potentially 600W power, and this figure is indeed necessary for high AIB variants like the ROG Astral GeForce RTX 5090, which would be A pretty unit swallowed with power. Nvidia provides users with the possibility of executing the GPU on 450W is indeed a large measure, because in this way, the company ensures that not having the right power does not affect the functionality of the GPU, But it will surely have an influence on performance.
Since the NVIDIA RTX Blackwell GPUs fell on the markets recently, we expect many more stories to take place, with a Be the brick networksDue to unknown problems probably associated with BIOS, on -board pilot or PCIE connection. Make sure you use your SKU in ideal conditions, because after the 12VHPWR fiasco, we can never be sure.
