Hot on the heels of Gigabyte, ASUS has also put its Thunderbolt 5 card up on its website, although there are some differences between the two. Obviously the physical appearance differs somewhat, but that's largely cosmetic. However, the one key difference is that the ASUS ThunderboltEX 5 only sports a single 6-pin PCIe power connector. ASUS still claims USB PD support of up to 130 W—a feature the company calls Flexible FastCharge—however, a single USB Type-C port is limited to a maximum of 96 W, which means you can charge your MacBook Pro at full tilt, but not some other laptops. Admittedly the 4 W discrepancy compared to the Gigabyte card is fairly minor, but the second port gets left with only 34 W, although that's still enough for charging most phones. Oddly enough, ASUS ThunderboltEX 4 card, allowed for up to 100 W on a single port.
