Incorrect Cables May Reduce NVIDIA RTX 5090 Performance

First owners NVIDIA GeForce RTX 5090 encountered an unexpected problem: Using improper power cables will result in poor performance. According to tests Computer Database, insufficient power supply can reduce FPS in games on 5% and more, which is especially important for high-performance systems.

main feature RTX 5090 - its high power consumption, which can reach 600 W. However, some users connect the video card via adapters with three 8-pin connectors instead of four, which limits nutrition to 450W or even 400W. In such cases, the video card works, but with a noticeable drop in performance. The most important thing is when using two 8-pin cables (300W) the card simply refuses to start, which is confirmed by tests.

The problem is especially relevant for overclocked versions of video cards from AIB partnersSuch as ROG Astral GeForce RTX 5090, which require maximum power consumption. Although NVIDIA leaves the possibility of working on 450 W, users should be aware that this mode has a negative impact on performance in games and benchmarks.

Owners RTX 5090 It is worth checking carefully the ones used power adapters, especially considering past issues with 12VHPWR connectors causing cables to melt. So far there have been no mass cases of failure because of nutrition not recorded, however, after reports of "deaths" of RTX 5090 and 5090D due to drivers and BIOS Users should exercise extreme caution when assembling their systems.

NVIDIA continues to test and update its drivers, but experts recommend using only 4x 8-pin connectors to achieve maximum performance and stability.
