ASUS RTX 5090 gets leaked 2000W XOC BIOS, but Matrix firmware still looks like the smarter pick
A new ASUS RTX 5090 XOC BIOS has surfaced on the Overclock.net RTX 5090 owner thread, shared by user Carillo as a file named 5090 Asus XOC. According to the discussion, this BIOS exposes a theoretical 2000W class power limit and raises the voltage ceiling to 1.15 V, pushing ASUS GB202 cards far beyond any official configuration. The build itself is not new, though. Forum users note that this is an older XOC BIOS compiled in 2024.
XOC BIOS images of this type are not casual mods. They are vendor firmware that must be signed and accepted by NVIDIA’s validation and security chain before drivers will load them. Access is usually limited to extreme overclockers, partner OC teams and a small group of board vendors, so such files rarely appear in public and NVIDIA is known to be strict about how and when they are distributed. In reality, though, eventually such BIOSes tend to leak to public forums anyway.

Despite the headline power limit, owners in the same thread point out that the practical cap on current retail RTX 5090 boards still sits around 1200 W, even with this XOC firmware. One user clarifies that the card cannot draw “unlimited” power and that you only get beyond 1200W when combining the BIOS with external voltage controllers and custom voltage tweaks. Another key detail is that this XOC BIOS immediately sets core voltage to 1.15 V, even with the software voltage slider left at zero. This makes the card pull large amounts of power in light loads or even game menus if you do not control the VF curve manually.
Earlier this year, YouTuber JayzTwoCents flashed the leaked Astral RTX 5090D XOC BIOS 1600W onto a GIGABYTE RTX 5090 AORUS Master, which on that non-D board capped out at a 1600W limit. Running the card at around 900 W with extra core and memory clocks yielded about 10% higher performance in 3DMark Port Royal compared to stock, but it also disabled one fan due to a mismatch in fan controller configuration between the ASUS and GIGABYTE designs.

More recently, ASUS 800W ROG Matrix BIOS has become the preferred “daily” mod in the enthusiast scene. That firmware, designed for the $4000-worth ROG Matrix RTX 5090 GPU, has been flashed onto several non ASUS cards from GIGABYTE, PNY and MSI. It delivers higher boost clocks and clear gains in demanding games and benchmarks without pushing into four digit power numbers.
For now, the 2000W ASUS XOC BIOS looks more like a tool for binning and voltage scaling tests than a new meta for gaming builds. It may help competitive overclockers probe how far a sample scales with voltage in lighter benchmarks. For owners of an RTX 5090 Astral or other custom cards running standard water loops, the safer and more effective path remains the Matrix BIOS or the stock vendor firmware.
Of course, under no circumstances do we encourage anyone to flash these BIOSes. You already have the fastest GPU on the market and possibly a few months of warranty left (in some countries it’s 1 year), so at least wait for that to end.
