Recently, it was reported that NVIDIA will release RTX 3090 Ti next year 1 month, with full blood GA 102 core, open all 10752 stream processors, equipped with 24G21GHz GDDR 6x video memory, and the bandwidth exceeds1TB/s. Such a high power consumption is bound to adopt at least the current 6+8+8PIN power interface, but it is rumored that RTX 3090 Ti will be equipped with a new interface of 12PIN power supply +4PIN signal designed for PCI-E 5.0 graphics card for the first time.

PIC SIG quietly formulated the standard specification of this new interface, named "12 vpwr H+", including 12PIN power terminal and 4PIN signal terminal. The maximum current of each power supply pin is 9.2A, which is 55.2A in total, and the corresponding voltage is 12V. A single port can provide a power supply capacity of up to 600W, which is four times that of the existing 8-pin (150W) and eight times that of the existing 6-pin (75W).

It is reported that some manufacturers have announced the schematic diagram of the new 12 vpwr connector. You can see that the wire diameter of the power interface is very thick, and the signal wire at the bottom is green and thin. This interface has a locking device. The official said that the maximum contact resistance of the plug is 6m? . NVIDIA has adopted 12PIN power connector in its original RTX 30 series. Although the corresponding AIC partners did not follow up, with the arrival of PCI-E 5.0 specification, it is imperative to replace the power interface.
