Flashing RTX 5090 With Asus 1,000W BIOS Delivers Additional Gains, But at Big Power Cost

It turns out the 1,000W special BIOS used for the ASUS ROG Astral RTX 5090 also works on other RTX 5090 GPUs, though the results aren't necessarily what one would expect. In one instance, YouTuber JayzTwoCents applied the BIOS to a Gigabyte RTX 5090 Aorus Master and found it did unlock an additional 10% performance when running at 900W, but oddly, one of the fans abruptly stopped working.

The RTX 5090 is a seriously powerful card, but it requires a lot of power. Even in its reference design form at stock clocks, it can still demand as much as 575W, and Nvidia recommends a minimum 950W PSU to cover transient power spikes and other demanding components. But there are some RTX 5090s out there with special BIOS and power configurations that allow them to draw much more than that.

It turns out that those cards aren't unique ...
