Q&A:

K993G

What external power supply options are available for the ADT K993G?
Only standard ATX power supplies are supported. The power rating should be selected based on the graphics card requirements.

What is the switch on the graphics card dock used for?

Flipping the switch to 1 activates automatic startup, allowing the dock to automatically start and stop with the computer. You don't need to flip the switch when the dock is operating normally. Flipping the switch to 2 forces the dock to start, directly powering the dock. If you're using an adapter board not from our store and the dock doesn't start properly when the switch is set to 1, flip the switch to 2 to force the dock to start. To ensure device safety, force the dock to start before starting the computer, and shut it down after shutting down the computer.
How do I read the device indicator light?

The D1 light indicates cable testing. Some cables not made by our store may cause the D1 light to be off. The D2 light indicates the ATX power supply status. If it's on, it means the ATX power supply is functioning properly. If not, please check that the power switch is on and the cables are properly plugged in. The D3 light may not illuminate when using some AMD graphics cards. The D4 light is normally off and only flashes briefly when turning the computer on and off. Normal operation requires the D2 light to be on and the D4 light to be off. The D1 and D3 lights are for testing purposes only; their off status does not affect normal operation.

Is there any EMI shielding for Cable?
With metal shielding. The cable uses the latest EMI shielding materials with full cable coverage shielding to prevent the incoming or outgoing of electromagnetic frequencies, minimizing interference and performance degradation, and reducing 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 0.8mm, so the wire is softer and can be bent or folded.

F4Q:

1.It can support M.2 NVMe interface up to 2280 height and can be cut as needed

2.Using Amphenol Oculink SFF-8612 connector, supports PCIe 5.0 full-speed stable transmission

3.UL certified PCB material, gold finger gold-plated 15µ", good conductivity, can reduce the blue screen problem caused by oxidation and rust resistance increase.

Test data:

3DMARK running data of the internal screen

Test platform:7600x + 5070 + Xingu 850W power supply (direct plug)

3DMARK running data with external screen

Test platform: 7600x + K993G + F4Q + 5070 + Xingu 850W power supply (using graphics card dock adapter)

Test Results: On the same platform, using a K993G graphics card with an F4Q adapter, the difference in 3DMARK graphics scores was less than 1%.
When using an external graphics card, it is recommended to connect an HDMI or DP cable to the graphics card to ensure external display output. Tested performance is approximately 6% higher than using the internal display.
