Features: The Quad NVMe PCIe Adapter allows you to add 4x NVMe SSDs simultaneously via PCI-e 4.0/3.0 x16 slot on the MOBO. Specification: Item Type: M.2 NVME SSD to PCIE X16 Adapter Material: PCB Support Hard Disk: M.2 NVME Protocol SSD, M.2 PCIE Device Transmission Speed: 4x32Gbps Motherboard support: The PCI-e 4.0/3.0 x16 Slot on Mobo is required to support PCIe x16 Bifurcation itself and could be set as"PCI-e x4x4x4x4" in BIOS. Compatible with: The following motherboards have been verified to support PCIe Bifurcation. GIGABYTE: X299X AORUS MASTER LGA 2066X, X299 AORUS, X299X DESIGNARE 10G, X299 UD4 PRO, X570 GAMING X, X570 AORUS ELITE,X570I AORUS PRO B450M AORUS ELITE, EVGA X299 FTW-K (need to update the BIOS to the latest version), EVGA X299 DARK (need to update the BIOS to the latest version). ASROCK:X570 CREATOR, X570 STEEL LEGEND, X570 TAICHI, X299 TAICHI, X299 DESIGNER, X399 TAICHI SUPERMICRO:X10 SDV, X11DAI-N ASUS: ASUS PRIME X299-A II, ASUS PRIME X299-DELUSE II, ROG STRIX X570-I GAMING, ROG STRIX X570-F GAMING ,ROG STRIX, X570-E GAMING, ROG CROSSHAIR VIII DARK HERO, ROG STRIX TRX40-XE GAMING, ROG RAMPAGE VI EXREME ENCORE, ASUS PRIME Z390-P, TUF, Z390-PLUS GAMING, ROG RAMPAGE VI EXTREME, ROG RAMPAGE VI APEX, ROG STRIX X299-XE GAMING, ROG STRIX X299-E GAMING, PRIME X299-DELUXE, PRIME X299-A, TUF X299 MARK 1, TUF X299 MARK 2, TUF GAMING X570-PLUS, More model please check ASUS support/FAQ/1037507 Package List: 1 x Expansion Card 5 x Nuts 5 x Screws 1 x Screwdriver?Note?Do not Support Hardware Raid, only support the formation of soft raid in Win10 , or you may build raid via Third-party Software, and the 4 SSDs should be same model. The motherboard need support "PCIEX16 Bifurcation",otherwise, only one M.2 SSD can be recognized. ?Compatibility?Compatible with M.2 PCI-e NVMe SSDs: 80x22mm, 60x22mm and 42x22mm, 30x22mm.(Do not support any M.2 (SATA-Based B+M Key) SSD); Motherboard: X299, X399 and Most Servers supporting PCIe x16 Bifurcation. ?Fan & LED indicator?The unique fan design on our Quad NVMe PCIe Adapter ensures efficient heat dissipation, preventing your SSDs from overheating and ensuring optimal performance. A single LED indicator will display the working status of each SSD. ?Hardware requirement?The PCI-e 4.0/3.0 x16 Slot on Mobo is required to support PCIe x16 Bifurcation itself and could be set as"PCI-e x4x4x4x4" in BIOS. All of the SSDs are M.2 (M Key) NVMe SSD. Besides, the CPU has enough channels supported. ?Quad NVMe PCIe Adapter?This adapter allows you to add 4x NVMe SSDs simultaneously via PCI-e 4.0/3.0 x16 slot on the MOBO which is required to support PCIe x16 Bifurcation. Full-speed transmission up to 4x 32Gbps.
