Convenient and practical: The Mini PCI E Gigabit Ethernet Card is a 1000Base-T Ethernet controller card, backward compatible with 10/100Base-T networks. Plug and play, with LED indicator. Chip and transmission: The mini Ethernet card adopts the Realtek RTL8111H main control chip, supporting high-performance dual-channel networking. The maximum data transmission rate in each direction is 1000Mbps (2000Mbps total). Heatsink and bracket: The mini Ethernet card is equipped with a low-profile bracket and a full-height bracket, supporting standard and ultra-thin computers and servers. The heatsink can effectively dissipate excess heat. Thickened gold-plated pins: The mini Ethernet card uses thickened gold-plated connectors to reduce hardware contact failures and avoid data packet loss and distortion. System support: The mini Ethernet card is applicable for Win 7, Win 8, Win XP, Win 10, Win Server 2008 R2, Win Server 2012, Win Server 2016, Win Server 2019, Linux 2.6.31 to 4.11.x LTS.
