ASHATA PCI-E to PCI-E Adapter Card PCI-E 1X to 4X PCIe USB3.0 Converter Extender Adapter Card Expansion Kit for Windows Linux Mac

Features: The slot on the motherboard can be directly led out from the slot or placed on the slot connection board connected to the chassis. PCI-E 1X multi-interface card solve the situation that the desktop computer PCI-E 1X is not enough. It consists of two parts, one is the main card, 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, which are connected by USB 3.0 cable. The device card is used for transfer between PCI-E and PCI-E. But even with USB 3.0, the theoretical bandwidth is only 5 Gbps (625 MB/s), and the loss is only 150 MB/s in four minutes, and even the single channel bandwidth of PCI-E 1.x is 250 MB/ s, so this can give you the most slots, but not enough bandwidth, only suitable for performance. Therefore, the PCI-E slot to be transferred is preferably 2.0 or higher, and 3.0 is better. Specification: Product Name: PCI-E 1 to 4 adapter card Product model: PCE4PCE-A01 PCB color: Blue Product Interface: PCI-E 1X Support system: Compatible with all for WINDOWS systems, for LINUX/MAC Size: Approx. 12 * 8.3 * 1.5 cm / 4.72 * 3.26 * 0.59 in Weight: Approx. 49 g / 1.73 oz Package Iist: 1 * PCI-E Card 1 * PCI Card 1 * USB Cable Note: The several PCI-E 1X slots that are separated are all in gen2 mode, even if they were gen1 before. This is a very good feature. Do not insert the PCI card reversely, and the reverse insertion will easily lead to burnout. For manual measurement of dimensions, there may be an error of 0 - 2cm, which is normal. Due to the differences between the different displays, the picture may not reflect the actual color of the item. Thank you!
