JEYI Quad NVMe PCIe 4.0 X16 Expansion Card with Heatsink Enclosure, Supports 4 NVMe M.2 SSD 2280 up to 8TB, Raid Bandwidth 256Gbps, Required Bifurcation

This adapter card uses 3.3V and 12V dual voltage power supply, 12V to 3.3V using dual 6A power modules to meet the power requirements of large power consumption SSD.
Points to note before purchasing.
1, please be sure that your motherboard PCIe x16 slot support PCIe Bifurcation - signal split into four PCIe x4, general ordinary motherboard if the BIOS inside the "PCIEX16 Bifurcation" and other similar options, options to go in after seeing "PCIE 4x4" and other similar settings generally support Bifurcation; server motherboard chips are not the same, please consult your motherboard official for details. If the PCIe slot can not be Bifurcation or BIOS is not set to x4x4x4 x4, only one hard drive can be recognized. If the motherboard can only be set to x8 x4 x4 can only recognize 3 disks.
2, if you want to group raid, please be sure to use four specifications of the same model of the same hard drive, so as to ensure consistency of hard drive performance. Can group raid is your motherboard decision.
3, some motherboards only support direct connection with the CPU PCIe slot support PCIe Bifurcation, if occupied then there is no place to insert the graphics card, please be sure to consider clearly before buying these.
4, some motherboards PCIe slot is bandwidth sharing, such as the first PCIe slot is PCIe x16, the second PCIe slot is PCIe x8, if the two PCIe slots are inserted at the same time on the device, because of bandwidth sharing reasons two PCIe slot is running PCIe x8 bandwidth. Assuming the second PCIe slot is not inserted into the device before the first PCIe x16 slot supports splitting into PCIe 4x4, but after the second PCIe slot is inserted into the device because the bandwidth is changed to PCIe x8, it will lead to splitting failure and not recognize the disk. There is also motherboards PCIe slot and U.2 is only one of two choices, please pay attention to read the motherboard manual.
5, please note that most motherboards must work with the CPU to work, low-end CPU does not support Bifurcation, because the number of PCIe channels is not enough.
