Vszerda Mini PCI-E Gigabit Network Card N34848

SKU CH-80AT-G0Y9S

A half-size Mini PCI-Express 1.2 card with Realtek 8111 controller adds a Gigabit Ethernet port to desktops using a single x1 lane

  • Rated speed1,000 Mbit/s
  • Key featuresDesktop
  • Gigabit Ethernet via single-lane PCIe x1 up to 2.5Gbps throughput
  • Works with existing CAT-5 cabling using automatic crossover detection
  • Compatible with Windows, Linux, DOS and MAC OS X 10.4.X or above
  • IEEE 802.3, 802.3u, 802.3ab compliant with 802.1Q VLAN tagging
  • Includes high and low profile brackets plus connection cable for easy install

Mini PCI-E Gigabit Adapter

The Vszerda N34848 adds a 1000 megabits_per_second Ethernet port to systems with an available Mini PCI-E slot. It suits owners of compact desktops or embedded boards that lack built-in gigabit networking. The half-size card includes high and low profile brackets plus a connection cable for flexible mounting.

Sustained throughput behaviour

The Realtek 8111 controller handles full duplex flow control under IEEE 802.3x and supports jumbo frames to 9K bytes, reducing interrupt overhead during long transfers. Backwards compatibility with 10 and 100 megabits_per_second networks ensures stable links even on older cabling. Auto-negotiation and crossover detection keep the connection negotiated without manual setup.

Deciding specification

The card requires a Mini PCI-E x1 slot compliant with revision 1.2 and the half-size Mini Card electromechanical form factor. Systems without this exact slot type cannot install the adapter. Buyers needing a full-size PCI-E card or a USB-based network interface must choose a different product.

Questions about this item

Does the Realtek 8111 chip run hot or draw much power when the link stays at 1000 megabits per second all day?

The card uses a single-lane PCI Express 1.1 interface capped at 2.5 gigabits per second, so the Realtek 8111 controller stays well within its low-power envelope even at continuous gigabit throughput.

My motherboard only has a full-size PCI Express slot — what extra hardware do I need to install this half-size Mini PCI-E card?

You need a Mini PCI-E to PCI-E x1 adapter bracket; the package includes high- and low-profile brackets and a connection cable, but the slot converter itself is not supplied.

Will this card negotiate down to 10 or 100 megabits per second on my older Cat-5 patch panel and legacy switch ports?

Yes, the controller is backwards compatible with 10 and 100 megabits per second networks and performs automatic crossover detection on existing Cat-5 UTP cabling.
