Is there any EMI shielding for Cable?

The extender utilizes the latest materials for EMI shielding with five sole flat cables design. This technique allows each cable to be fully covered by electromagnetic interference shielding with conducting polymer to guard against incoming or outgoing emissions of electromagnetic frequencies, minimize disturbance and degradation on performance, and reduce the weight of the extender.

What is the thickness of the cable? Is it soft? Can it be bent?
The thickness of the cable wire is 1.4mm, so the wire is softer. The wire can be bent or folded, but do not pull it.

Cable Length Description:

R3G series cable length has 25 cm or 50 cm can be selected, the following is the line length of 50 cm. refer to the blue dimension of the figure below.

Power Supply Description:

Supporting power supply is DELL DA-2 8PIN 12V/18A/220W PSU, or standard PSU power supply. The power supply should be prepared by the buyer or purchased separately.


24P_ATX and 4P_CPU power input, Dual 8P_GPU power output.

DELL DA-2 8PIN Input. Dual 8P_GPU power output.

Product accessories, enclosed with the following graphics card power cord below

SW1, Power Forced Start Switch, 1 for automatic startup, 2 for forced startup, please cut to 1 for automatic startup.

SW2, PERST # signal delay switch, 1 delay 2.2 seconds, 2 delay 4.5 seconds, with eGPU software, for graphics card compatibility optimization, the current software does not support, please cut to 1

SW3, CLKRUN # signal delay switch, 1 is closed, 2 is delayed for 9 seconds, with eGPU software, for graphics card compatibility optimization, the current software does not support, please cut to 1

J1, PERST # signal delay switch, OPEN to open delay function, SHORT to close delay function, the current software does not support, please insert the jumper cap SHORT.

J2, CLKRUN_Capacitance Delay, currently the software does not support, only for R&D engineers plug in capacitance adjustment delay testing. It takes about 2.2 seconds to insert a 1uF capacitor, 5 seconds to insert a 2.2u capacitor, and so on.

Installation steps:

1. Install the hexagonal copper pillar and insert the graphics card into the PCIe x16 slot. The screw is tightened so that the graphics card will not shake or fall off.

2. Install ATX power supply or DELL power supply, including graphics card power cord should also be connected, after installed, DELL power supply will light orange lights.

3. You can plug in the M.2 cable when the computer is off. After power on, the ATX power supply will automatically start the fan to turn. If you use the DELL power supply, the green light will turn on. At this time, the R3G board will turn on two green lights. The system will recognize the card automatically. Please install the graphics card driver. The installation of the driving process may prompt the computer to restart.

4. finish.

ADT R43SG is PCIe 4-Lane 8Gbps bandwidth limit passive adapter in compliance with PCI express 3.0 specification
R43SG design for engineering test. NOT for home or office use.
Basically, PCIe add-on card designed for desktop. We can’t guarantee it compatibility with your laptop. Depends on OS version, notebook’s BIOS, device driver,
Almost PCIe 16x video card can’t get enough memory resource are allocated. Can’t work in your laptop.
External Power (ATX Power or AC-DC12V adapter) required.
All of interoperability is not guaranteed.
