According to the principle of high-speed differential signaling
PCIe I / O interface, x16 is = 164pin;
So do not want to be the victim of inferior products,
Do not buy the total number of wiring, or power specifications marked unclear products,

Case 1:
Less than 164PIN
So the performance is problematic
And the power supply specifications are too low
There is also the risk of burning
Case 2:
Some wires do not cover EMI
Power supply specifications are too low
It is recommended to use 28AWG (2651) to improve safety
Can immediately improve safety
Reaching a minimum of 25W
If he finished the job
Will be our recommended

The PCIe flexible riser card has standard features
1. Integrated flat shielded cable with x16 total number of wires = 180pin (AWG # 30)
2. 12V = 2.4A (AWG # 30 * 12); 3.3V = 1.4 + 0.4A; maximum support 35W of the TDP value
3. 1.8 mm in thickness and 57 mm in width (Flexibility is the best)
4. Welding feet and power lines are in the EMI shielding layer inside

Solutions Board Option I
Because of the patented technical means, the total number of 16x wires is ≒ 181 pin; 3M ™ Twin Axial with GEN4 is supported by silver plating;
Some wires do not cover EMI

Solutions Board Option II
(2) .16x the total number of wires = 164pin : 12V maybe=2.5A; 1M length can be customized, the cable can be twisted into a beam of Amphenol
Some wires do not cover EMI
