DC-DC step-down
IC: Using an independent DC-DC power supply circuit, 12V is stepped down to 3.3V, supporting high current 4A, and provided to M. 2 socket. This adapter card is a physical conversion, without driver or power consumption. Please power off for operation.; This adapter requires the motherboard BlOS to support X8x4X4 split settings. If the motherboard does not support settings, only PCIeX8 can work.; lf the motherboard only supports X8X8 settings, only PCle X8 and SSD1 on the back can work.; If the motherboard only supports X4X4X4X4 settings, the PCIEX8 will operate in PCIE mode X4, and both SSD1 and SSD2 can operate.; The maximum working speed of this adapter card is PCIE 4.0, supporting PCIE 4.0 /PCIE 3.0 graphics cards, network cards, and solid-state drives. lf a PClE extension cable is used, it may cause instability or slow down to PCIE 3.0.
