Nvidia a while ago RTX 5090 ve RTX 5080 having cards RTX 50 introduced the series graphics cards. New cards announced ATX 3.1 While it was announced that it was compatible with the standard, it was up in the air whether users who already had power supplies should upgrade or not. Finally, Igor’s Lab conducted a comprehensive analysis of the power management of the GeForce RTX 5090. This analysis provides important information, especially for users using older power supplies and converting four 8-pin PCIe power connections to 12V2x6.

901.1 W in less than 1 ms

For those who missed it, it powers the GeForce RTX 5090 GB202 GPUIt is one of the most powerful chips Nvidia has ever produced. Based on TSMC’s 4N manufacturing process GPU, 92.2 billion transistors and to a surface area of ​​750 mm² owner. As for these features, 24,576 CUDA cores, 192 fourth-generation RT cores ve 768 fifth-generation Tensor cores is accompanied.

As for power consumption, there will be those who remember the RTX 4090, which remained on the agenda for a long time with its power consumption as well as the performance it offered. If it is RTX 5090, 575W maximum power consumption It works with. However, it has some innovations in terms of energy efficiency, such as separate voltage rails for GPU cores and memory and an accelerated clock frequency switching mechanism.

When we look at the test results, we see that the RTX 5090 runs between 10 ms and 20 ms. up to 627.5W; in periods of 5 ms to 10 ms up to 738.2 Win the 1 ms to 5 ms category up to 823.6WWe see that it can reach high fluctuations up to 901.1 W at times below 1 ms. However, those exceeding the power limit of these values ​​(600 W) short-term power increases Let’s say it represents.

Power consumption peak values

  • 10–20 ms 627.5 W during
  • 5–10 ms 738.2 W during
  • 1–5 ms 823.6 W during
  • in less than 1 ms 901,1 W

Although these values ​​\u200b\u200bseem scary, they comply with the ATX 3.1 standard. Likewise, ATX 3.1 allows power fluctuations of up to 200% (1200 W) in increments of less than 1 ms. Therefore, ATX 3.1 compatible PSUs can meet these values ​​without any problems, even if they have a continuous power capacity below 1200 W. Older ATX v2.51 PSUs, that is, from the 2010s, may cause various problems such as overcurrent protection (OCP) triggering when they reach these values.

In addition to peak values, RTX 5090 idle Power consumption from 28.4W to 35.5W owner. This value is also related to the resolution and refresh rate used by the monitor. Finally, the graphics card consumes 241W in standard use and 591W in 4K gaming experience.
