Intel ATX 3.0 power supplies with 16-pin PCIe 5.0 connector will be "smart"

The growing need for more powerful power supplies to handle the latest, powerful graphics cards has led to the creation of a new 16-pin connector capable of delivering the right current to devices without problems, while offering a design to reduce the amount of cables inside the PC. The result was the 12VHPWR connector, which looks very similar to that used on the NVIDIA Founders Edition RTX 30 series graphics cards, formally known as Molex MicroFit 3.0 dual row, which has 16 connectors in total, four of which use a separate series. of contacts currently carrying sideband signals that validate the correct connection of the board and determine the maximum starting power that the device can obtain from the power supply.

The power supplies equipped with the connector designed for the new generation PCI Express 5.0 video cards also have two different states: the first defines a limit of power delivered when the system is switched on and in the start-up phase, while the second concerns the limit reached when the video driver is loaded. For further details on how it works, we advise you to take a look at the tables attached to the news.
