Although the 12V-2x6 16-pin power supply interface has a maximum power supply capacity of 600W, some flagship graphics cards still have two.Uniko's Hardware is even more bold, adding a second 16-pin power supply interface to a Gigabyte RTX 5090 Super Sculpture for extreme overclocking.
The prerequisite for this is that the second 16-pin power supply interface is reserved on the PCB of the graphics card, but it is not used because it was originally prepared for the STEALTH series, and it is very common for different graphics card models to share the same PCB solution.
The transformation was complicated, but very successful. Unfortunately, the happiness was short-lived. The card burned out the day after the transformation...
The inspection revealed that a capacitor in the power supply circuit had exploded, leaving a large hole in the PCB.
They sent the card to Northwest Repair, a well-known repair organization, which is still working on it.The initial suspicion may be related to the improper use of the heat gun during the modification.
Let's see if there are any miracles.
