High Power PCIe Gen5 power connector for next-gen GPUs pictured, up to 600W
Earlier this week [we published] an article about the upcoming flagship GeForce RTX 3090 Ti graphics card, which is now set to launch in January. The graphics card is supposedly the first card to feature a PCIe Gen5 power connector, a new standard that will ultimately solve one of the biggest drawbacks of the current 8-pin power connector, an insufficient power it can provide (up to 150W).
Igor Wallossek from Igor'sLAB managed to obtain the schematics and the information on the new connector, confirming that there is indeed a new standard coming, possibly to all new graphics cards in 2022.
Just as we said, the power connector has 16 lanes in total (12 power and 4 signal lanes), but it's not a MicroFit Molex standard, but something entirely new. The standard [as defined] has smaller spacing than existing connectors, a change from 4.2 mm to 3.0 mm. The connector has a width of 18.85 mm, so it is not exactly small, but much smaller than dual or triple 8-pin connector configuration. This will greatly simplify the circuit and PCB design process, not to mention all the space that will be saved.
The PCI-SIG specs define that each pin can sustain up to 9.2A, which means a total of 55.2 A at 12V. This gives a maximum power of 662W, but the specs officially go up to 600W, Igor notes. Along with twelve pins for power, there are [an] additional 4 signal lanes right underneath the connector. At this moment it is unclear what [their purpose is] or whether they are required or optional.

xx90 are not intended for gaming. These are made for fast 3D pre-rendering or for AI computation in cases where you do not want to bother with a cluster. Their idle power consumption is just stupid (115W) and these are really noisy.

While the RTX 3090 should be considered a "prosumer" card, great for making your celeb deepfakes, it's also marketed towards gamers. Some gamers bought one for nearly $2,000 simply because it was available during the ongoing GPU pricing fiasco and/or it's the best.

The RTX 3090 is not for everyone, but its existence and specs are at least understandable. The weirdest thing has been the segmentation and VRAM of the lower cards, particularly the fake MSRP RTX 3060 with 12 GB of VRAM. And soon we may see an RTX 2060 with 12 GB of VRAM [tomshardware.com]. AMD caused Nvidia to turn its lineup into a clusterfuck.
