4X PCIe extension 19cm Cable riser card

A Peripheral Component Interconnect (PCI, "Peripheral Component Interconnect") is a bus (picture 2) computer standard for connecting peripheral devices directly to your motherboard. Dimensions of the cards - PCI (standard) 107 mm x 312 mm (picture 1) - PCI Low Profile Height: 36.07 mm x 64.41 mm Depth: 119.91 mm to 167.64 mm - Mini PCI Mini PCI cards have a Maximum consumption2W.

Riser Card (A) is the name given to the board that contains the printed circuit, which through signal connectors is capable of transmitting data and power using a single connector.

This type of connector is compatible with motherboards or expansion slots (B), which is responsible for managing and distributing the signals, although we can also find that this communication is carried out by cable, using flex connection hoses.

The main function of a riser card is to be able to adapt an expansion card (C) in a system in which it is possible due to size or distribution, normally creating an angle of 90° between the plate and the card.

For example, a riser card could be used in a low profile PC to accommodate a larger size card or a 1U PC case could be fitted to accommodate larger cards.
