product information:
Product name: PCI-E 1X to 4 PCI-E 1X riser card
Product interface: PCI-E 1X
Support system: compatible with WINDOWS system, LINUX

Features:
If you need multiple PCI-E x1 slots, but there are not so many on the motherboard, this riser card can expand the PCI-E 1X slot on the motherboard to 4 PCI-E 1X slots to solve the motherboard The problem of insufficient slots.
It consists of two parts, one is the main card, which is installed on the motherboard through the PCI-E x1 interface, and the other is the device card, which has three or four PCI-E x1, and the two are connected together through a USB 3.0 cable.
The device card is used to transfer between PCI-E and PCI-E.

Transmission speed description:
Even with USB 3.0, the theoretical bandwidth is no more than 5Gbps (625MB/s). If you divide it into four and remove the loss, it will only be 150MB/s. Even the single channel bandwidth of PCI-E 1X is 250MB/s.
Therefore, this adapter card can only give you the most enough slots, but not enough bandwidth. It is 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.

Note:
The 4 expansion 1x slots are all in GEN2 mode, even if they were in gen1 mode before. It is a good choice for old motherboards.

Package Iist:
1 * PCI-E Card
1 * PCI Card
1 * USB Cable
1 set * Screws
This riser card can expand the PCI-E 1X slot on the motherboard into 4 PCI-E 1X slots, thereby solving the problem of insufficient motherboard slots.
The 4PIN and SATA interfaces enhance the power supply capacity, thereby reducing the burden on the motherboard.
This adapter card is a hardware adapter, driver-free, plug and play.
It consists of two parts, one is the main card, which is installed on the motherboard through the PCI-E x1 interface, and the other is the device card, which has 4 PCI-E x1, which are connected through a USB 3.0 cable, and is used for PCI-E and PCI-E. Transfer between.
The 4 expansion 1x slots are all in GEN2 mode, even if they were in gen1 mode before. It is a good choice for old motherboards.
