ASUS Launches the Second Generation of Thunderbolt 3 Expansion Card, Which Supports 40Gbps Rate and 100W and Has an Excellent Fast Charging Performance
The 400-series chipset motherboard blossomed after the intel 10-generation processor went on the market. ASUS introduced the second-generation Thunderbolt 3 expansion card for the 400-series motherboard, which supports two 40Gbps ultra-high-speed Thunderbolt 3 interfaces, has strong power transmission performance, and supports 100W+27W PD fast charging.
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.
Let’s take a look at the chassis baffle of ASUS Thunderbolt 3 expansion card, which has four interfaces, namely two Thunderbolt 3 interfaces and two Mini DP video input interfaces. The first Thunderbolt 3 interface supports 40Gbps data transmission rate and 20V5A 100W PD fast charging function, and the second Thunderbolt 3 interface supports 40Gbps data transmission rate and 9V3A 27W PD fast charging function. They all support the image format of 8K Ultra HD.
In addition to a Thunderbolt 3 expansion card, the accessory package also contains four connecting cables, namely a USB2.0 pin flat cable, two DP to Mini DP video data cables and a 14-1 pin Thunderbolt Thunderbolt 3 pin flat cable.
In terms of interface, ASUS Thunderbolt 3 expansion card adopts PCI-E 3.0 x4 slot, with a 6 Pin power supply jack in the upper right corner, which provides powerful power support for the expansion card by inserting PC power supply, so that it can get 100W PD fast charging output.
ASUS Thunderbolt 3 expansion card is applicable to motherboards with TB-HEADER slots such as ASUS ROG MAXIMUS XII, STIRX Z490, GAMING Z490, PRIME Z490, TUF GAMING H470, etc. For specific models, please refer to ASUS official website for detailed support list. In terms of price, the price of ASUS Thunderbolt EX3-TR Thunderbolt 3 expansion card is 799 yuan, and you who are interested in it can buy it by yourselves.
