The subsequent technology of graphics playing cards are anticipated to attract a lot of energy, however I hadn’t anticipated to see considered one of at present’s finest and brightest sapping a lot from the wall. An Nvidia RTX 3090 Ti has been modded to unlock a 890W energy restrict, almost double the cardboard’s typical 450W restrict.
Why you’d do such a factor is to organize your graphics card for excessive overclocking—I am speaking liquid nitrogen overclocks to interrupt world information, and people which run the danger of frying or freezing your expensive parts for good. Sport overclocking, if you’ll.

The aptly-named MegaSizeGPU has posted a screenshot of what they declare to be an Asus RTX 3090 Ti TUF operating with an influence restrict of 890W, as noticed by Videocardz. The outlet additionally says the consumer has confirmed the GPU is operational, regardless of being far in extra of even the facility limits of the extra excessive RTX 3090 Ti fashions out there.
I might normally avoid photographs taken of a display screen as proof of something—these can so simply be faked—however there’s ok motive to imagine that such a feat might be attainable with a specialised BIOS.
The precise BIOS utilized by MegaSizeGPU has since been uploaded to TechPowerUp, courtesy of its creator, and has been designed for Asus Strix LC, Asus TUF, and Founders Version fashions. These types of BIOS, often called XOC (excessive overclocking), are used comparatively typically in record-breaking makes an attempt, and permit for better energy supply when pushing silicon to the extremes.
Which means you may do that BIOS out for your self, although I would not advocate you do. You run the numerous danger of bricking your chip with out due care and talent, and even then it is nonetheless actually dangerous.
Even should you wished to offer it a go, most RTX 3090 Ti graphics playing cards are ill-equipped to obtain that a lot energy; not solely in how they cope with that energy by means of the onboard VRM parts however by means of the cables themselves. The usual RTX 3090 Ti connector can obtain as much as 600W by means of a single 16-pin connector.
Some playing cards designed for excessive overclocking do get round this, nonetheless, together with EVGA’s RTX 3090 Ti Kingpin and Galax’s HOF OC Lab Version. These two playing cards include twin 16-pin PCIe energy connectors, which in principle max out at a whopping 1200W when mixed. The EVGA card even has a XOC BIOS that unlocks a 1000W energy restrict. Crikey.
You would additionally solder your personal mods to a PCB and attempt to inject extra energy that method, however that is not your on a regular basis improve.
A graphics card truly operating at 1200W might be not going from this technology, irrespective of how a lot liquid nitrogen you throw at it. Hearsay has it Nvidia might be enjoying with the concept of a 900W GPU with the following technology, often called Ada Lovelace, however that is certainly only for funsies within the lab, certainly?
