NVFlash, the new version also supports NVIDIA's RTX 30 series
For those who don't know it, NVFlash is a flashing tool that allows you to write a new BIOS of our same card model or, even more interesting, especially for overclocking enthusiasts, a BIOS coming from a different product, perhaps higher-end, to obtain some benefits. This is a fairly common practice with the Pascal and Turing generations of cards, and flashing a BIOS with a less restrictive power limit on a lower level card can extend overclocking capabilities. In fact, prior to NVIDIA's Pascal generation it was possible to manually change your BIOS, which is the preferred method of increasing performance. However, the Californian company has decided to block this practice by encrypting the BIOS to prevent any changes from Pascal onwards.
Now, all we have left is to flash the graphics card's BIOS, as we are not modifying the actual BIOS, and that's still something we can do to hopefully achieve higher clock speeds. Technically, just fetch the BIOS from another card with the same GPU (e.g. RTX 3080 Founders Edition to put it in an RTX 3080 TUF Gaming, or vice versa) and it should work.
Obviously this is a practice potentially risky as it is not certain that the operation is always completed without problems. In the worst case scenario, the graphics card will be completely blocked and, as a result, the warranty will no longer be valid as a fundamental component of the device has been modified without authorization. However, many overclockers don't mind this and, for them, the potential performance gains are worth the risk.

The Corsair RM750x PSU is a great 80 Plus Gold certified power supply, great if you are planning to upgrade to the series. RTX 30. You can find it on offer on Amazon.
