The full name of ASUS second generation Thunderbolt 3 expansion card is ThunderboltEX 3-TR EXPANSION CARD, with built-in Intel Thunderbolt 3 JHL7540 controller. Generally speaking, there are two ways to support the Thunderbolt 3 interface on the motherboard. One way is to integrate the Thunderbolt 3 interface on the motherboard I/O backplane, which has the advantage of convenient installation and use, but the disadvantage is that the power supply is limited by 5V3A;; The other is to realize Thunderbolt 3 function through expansion card, which has the advantage that 100W ultra-high power PD fast charge can be obtained by external power supply, but the disadvantage is that the price is relatively expensive. ASUS ThunderboltEX 3-TR Thunderbolt 3 expansion card belongs to the latter one, which has powerful power transmission performance and supports 100W PD fast charging.
