Intel ATX v3.0 power data exposure: Supports PCIe 5.0 power supply standard



 

Intel ATX v3.0 power data exposure: Supports PCIe 5.0 power supply standard. 

According to previous information from various channels and new products of power supply manufacturers, we have roughly learned about the characteristics of the new PCIe 5.0 external power supply interface.

It can meet the PCI-SIG’s “12VHPWR High Power Connector (H+)” standard through 12+4Pin full specification wire, and the rated power can reach 600W.

This new interface is very important for future PCs using high-performance graphics cards.

Recently, some netizens have exposed some documents of the ATX v3.0 design guide, showing that Intel has incorporated 12VHPWR into it, and provides a good overview of the new power transmission specification through pictures and text.

12VHPWR is also the PCIe 5.0 external power supply interface, with a total of 16Pin (12Pin power supply + 4Pin signal transmission).

 

The chart confirms that the width of the wire connector is 20.85mm, which is slightly wider than the current 8Pin external power connector (19mm).

The table also indicates the pin definition of the wire connector that meets the 12VHPWR H+ standard and up to 600W.

Among them, 6 pins are used for 12V power supply, the current of each pin is up to 9.2A, and the theoretical maximum output power is up to 662.4W.

It is still unclear what the 4 pins used for signal transmission are, and some people speculate that they are used to confirm and feedback the integrity of the graphics card power connection.

If the power supply is not equipped with a PCIe 5.0 external power supply interface, users can also use an adapter cable to achieve the same effect through three 8Pin external power supplies, which can be used on the next-generation graphics card.

Of course, cables using the PCIe 5.0 external power supply interface are always more convenient for wiring and take up less space.

 

There have been many new products released by power supply manufacturers equipped with the new PCIe 5.0 external power supply interface.

Among them, Cooler Master even launched the SFX Platinum power supply with a rated power of 1300W, which is used to build a new generation of high-performance Mini-ITX systems.

Compared with the commercially available SFX power supply, the improvement is amazing.
