1. Increase the filter circuit, signal transmission without interference! The high and low filter circuit composed of 6 different specifications aluminum capacitors and core SMT capacitors, the operation is not affected by the outside world 2. The product board is a low wave fiber board resistance, and each board must be tested for resistance 3. In order to solve the problems of poor heat dissipation of the product and easy pin shorting when fixing, 4 rubber poles have been added, and the height is unified according to the specifications of the computer motherboard. Small design, big effect 4. This mini PCI-E 16x adapter with USB cable is relatively soft and easy to follow, you can place the graphics card at will 5. The 6 pin interface on the graphics card can improve the DC power supply -DC, make the graphics card independent of the motherboard and reduce the load on the motherboard when connecting multiple graphics cards Color: random color (red, blue), do not accept the specified color Material: PCB Size: 12 x 3 x 1.2cm Package Contents: 1 x PCI-E Adapter Only the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The allowable measurement error is +/- 1-3 cm.
