JAENFONG M.2 M Key/PCI-E X1 to 4 PCI-E X16 Expansion Card 1 to 4 Port PCI Express Switch Multiplier HUB 6pin Sata USB Riser Card for BTC Miner Ethereum Mining ETH (M.2 M Key Port)

olor: blue

Specification: PCI-E 1X 1 to 4 / M.2 M KEY to 4 ports PCI-E 1X

Product interface: PCI-E 1X, M.2

Support system: Compatible with all WINDOWS systems, LINUX MAC

Features:

The PCI-E 1X multi-interface card solves the problem of insufficient PCI-E 1X in desktop computers.

If you need multiple PCI-E x1 slots and the motherboard is not enough, you can consider this riser card.

It consists of two parts, one is the main card, which is installed on the motherboard through the PCI-E x1 interface,the second is the device card, which has 3x or 4xPCI-E x1,they are connected together via a USB 3.0 cable.

The device card is used for the transfer between PCI-E and PCI-E.

When it is used with USB 3.0, the theoretical bandwidth is only 5Gbps (625MB/s),1 to 4, after removing the loss, it will only be 150MB/s.

And even the single channel bandwidth of PCI-E 1.x has 250MB/s,this adapter card can give you enough slots, but not enough bandwidth.

Only suitable for places where performance is not required.Therefore, the PCI-E slot to be transferred is preferably version 2.0 or higher, and version 3.0 is better.

Package includes:

PCIe 1X multi-port riser card * 1

Connection line * 1
