On April 13th, it seems that it is rare to hear about the RTX 4090 burned down because of the new 12VHPWR 16-pin power connector, but in fact it has never stopped, and it has been a lot.
Graphics card repair shop NorthridgeFix disclosed that they receive daily repairs from burned out RTX 4090s from all over the world.
There are no exact statistics, but the average number is 200 per month, or even more.
As proof, they released a photo of a box full of burned-out joints:
The good news is that the upgraded interface 12V-2x6, which NVIDIA replaced later, generates significantly less heat, and has not burned out once so far.
The bad news is that the RTX 4090 of the original interface is heavily used, and they all have the potential to burn out at any time.
It is worth mentioning that many burned RTX 4090s use the adapter originally designed by CableMod, which was intended to protect the interface and power cord, but the result is very unsatisfactory, and the later upgraded version is much better, but many people are still using the original version.
For mainland and Hong Kong and Macau players, it will be more troublesome if they encounter the RTX 4090 burned out, as well as various other chip-related failures, because it has been banned and may not be able to find a new one.
For Taiwanese brands, they are generally sent back to the original factory in Taiwan for processing, but the RTX 4090 cannot be sent back if it is missing, so most of them will be refunded.
For mainland or Hong Kong brands, the repair situation depends on whether there is an RTX 4090 chip, and the time is not easy to say, and many can only be refunded, or a preferential price for RTX 4090D is provided.
