Alexander "peter bjorn" Fadin If the proper cables are not attached to NVIDIA's most recent GeForce RTX 5090 graphics card, its performance may suffer.
Tests have shown that using 3x 8-pin cables can cause performance degradation of up to 5% in bitmap tests.
According to ComputerBase, using the wrong power adapter can limit the performance potential of NVIDIA's new flagship. Tests conducted using 3x 8-pin and 4x 8-pin adapters showed that a power reduction of about 100W results in a 5% performance drop. The GPU worked fine with three connectors, but failed to boot when only two 8-pin cables were plugged in. This means that the RTX 5090 does not work at 300W.

Using 4x 8-pin power connectors provides the GeForce RTX 5090 with up to 600W of power, which is especially important for non-reference models like the ROG Astral GeForce RTX 5090 that require more power. NVIDIA allows the card to use 450W for compatibility with different configurations, but performance doesn't suffer.
Considering that the RTX Blackwell series has just hit the market, we can expect new reports about its use. There are the first reports about possible problems with BIOS, drivers or PCIe connectors that may cause the card to malfunction.
