2.5GbE PCIe 2.0 x1 network card

The Vogzone VG-RLT8125B adds a single 2.5GbE RJ45 port to any desktop with a free PCIe x1, x4, x8 or x16 slot. It uses the Realtek RTL8125BG controller and supports Windows, Linux, macOS and major hypervisors except ESXi 7.0 and 6.5. A low-profile bracket is included for small-form-factor cases.

Sustained throughput with Jumbo Frames

The card negotiates 100MbE, 1GbE or 2.5GbE over copper and maintains line rate under continuous load thanks to Jumbo Frame support and DPDK compatibility. Features such as PXE boot, VLAN tagging and Wake-on-LAN remain active during long transfers, making it suitable for server and NAS workloads.

Low-profile build with single RJ45

The compact PCB measures 5.5 in by 3.5 in by 1.1 in and fits tight chassis without blocking adjacent slots. Only one copper port is present, so systems needing multiple 2.5GbE links or fibre connectivity must add further cards. The bundled bracket allows installation in both standard and low-profile brackets.

商品問答

How much power does the Realtek RTL8125BG controller draw when the card runs at 2.5GbE all day?

The card uses a PCIe 2.0 x1 slot which supplies up to 10 watts, so the RTL8125BG controller stays well within that envelope during continuous 2.5GbE operation.

What slot and bracket does the Vogzone VG-RLT8125B need to install in my desktop?

It requires a free PCIe x1, x4, x8 or x16 slot and ships with a low-profile bracket for small-form-factor cases.

Will this 2.5GbE card negotiate down to 1GbE on my older Cat5e patch panel?

Yes, the single RJ45 port auto-negotiates at 100MbE, 1GbE or 2.5GbE, so it works with existing Cat5e or Cat6 cabling.
