PCB Design and Layout
As mentioned earlier in the article, Nvidia actually has two reference designs for the PCBs for the RTX 3000 series. One of these designs has been used exclusively by Nvidia itself in its RTX 3000 series Founder’s Edition cards. These cards use a shorter PCB with a proprietary 12-pin connector that needs adapters to work with traditional PSUs. This shorter PCB also has a different placement of the power delivery elements on the card.
The other reference design has a bit longer PCB and uses traditional 8-pin power connectors instead of the 12-pin connectors. These reference PCBs are meant to be used by the AIB partners in their own graphics cards with the RTX 3000 series GPUs. The Palit Gaming Pro RTX 3070 also uses this reference PCB design, with a number of tweaks to optimize the design according to Palit’s standards.
