This RTX 3090 Ti running at an extreme 890W is one of the thirstiest GPUs yet
The next generation of graphics cards are expected to draw a lot of power, but I hadn't expected to see one of today's best and brightest sapping so much from the wall. An Nvidia RTX 3090 Ti has been modded to unlock a 890W power limit, nearly double the card's usual 450W limit.
Why you'd do such a thing is to prepare your graphics card for extreme overclocking—I'm talking liquid nitrogen overclocks to break world records, and those which run the risk of frying or freezing your pricey components for good. Sport overclocking, if you will.

The aptly-named MegaSizeGPU has posted a screenshot of what they claim to be an Asus RTX 3090 Ti TUF running with a power limit of 890W, as spotted by Videocardz. The outlet also says the user has confirmed the GPU is operational, despite being far in excess of even the power limits of the more extreme RTX 3090 Ti models available.
I'd usually steer clear of images taken of a screen as proof of anything—these can so easily be faked—but there's good enough reason to believe that such a feat could be possible with a specialised BIOS.
The exact BIOS used by MegaSizeGPU has since been uploaded to TechPowerUp, courtesy of its creator, and has been designed for Asus Strix LC, Asus TUF, and Founders Edition models. These sorts of BIOS, known as XOC (extreme overclocking), are used relatively often in record-breaking attempts, and allow for greater power delivery when pushing silicon to the extremes.
That means you could try this BIOS out for yourself, though I wouldn't recommend you do. You run the significant risk of bricking your chip without due care and skill, and even then it's still really risky.
