Asus tempts fate, unleashes 800W "XOC" vBIOS for its $4,000 ROG Matrix RTX 5090 — Overclockers and high-end GPU junkies now have their hands on the hottest, most power-hungry 5090 around

Modded RTX 5090s pushing past their 600W power limit, thanks to a custom 800W XOC BIOS from Asus' ROG Matrix GPU.

Nvidia's RTX 5090 GPUs, while unparalleled in performance, are also at the top of the leaderboard when it comes to burning down involuntarily. Asus — arguably the most prominent AIB partner for Nvidia — has dared to step into the ring and present something even more adventurous: The ROG Matrix RTX 5090, powered by a custom PCB capable of consuming up to 800W through its special firmware. Now that 800W VBIOS has escaped into the wild, users with otherwise standard, 600W RTX 5090s are experimenting with the unlocked overhead.

Peeking at the Overclock.net forums (page 1202 onwards) will show you various folk flashing the 800W XOC BIOS on their cards as soon as Benni231990 first posted the link for it a couple of days ago. It's relatively straightforward to install with NV Flash, but not every model is compatible right away. Variants like Gigabyte's Aorus Xtreme Waterforce can easily accept this firmware, likely because they match the ROG Matrix's three-channel fan header setup.
