PCIe 5.0 external power supply is up to 600W, Will be used in the next generation GPU

Last week, there was news that Nvidia’s GeForce RTX 3090 Ti launched early next year will use GA102-350 cores and have complete specifications, that is, 10752 stream processors, equipped with 24GB of GDDR6X video memory, the rate has reached a higher 21 Gbps, and the new 2GB module is used to replace the existing 1GB module. Even more impressive is the 450W. For this reason, the new 16Pin external power interface is likely to replace the previous 12Pin interface.

This 16Pin external power interface has a total of 16 channels, including 12 for power supply and 4 for communication, but this is not a Micro-Fit Molex standard, and a brand new design called PCI-SIG 12VHPWR H+. In its standard definition, the spacing is smaller than that of the existing external power interface, from 4.2 mm to 3 mm, and the width of the entire interface is 18.85 mm. Although the size is not small, it is still smaller than the dual 8Pin or three 8Pin configurations, which will simplify the circuit and PCB design and save more space.
