[SOLVED] Z390-A PRO Why do it need a PCIE_PWR1

[rabgade]

Hello.

I have a Z390-A PRO.

Why should it have an extra PCI on the motherboard. My graphics card needs 2. Then I don't have enough from power supply

In your link, go to page IX and click the youtu.be link, top left, to see a video. It is not a PSU connector for your graphics card. It is a 4 or 8 pin EPS connector.

The 6-pin pci-e connection on the motherboard is to supplement power to the pci-e slots when using multiple pci-e cards.

Yep.

This has been a thing since at least Z97 / X99, probably earlier. My X99 Extreme3 has one of these above PCI_E1.
