Genuine Intel 82574 · Single-Port Gigabit · PCI-E x1
Fits any slot. Fits any build.
You didn’t plan on buying a network card today. The onboard port just stopped working, or the router build came up one port short, and now you need it solved — not researched.
This is the card that ends the problem.
Any slot will take it. PCI-E x1 is physically compatible with x4, x8 and x16 slots. No slot hunting, no compatibility guessing. Find an open lane, push it in, done.
Any case will take it. At just 70mm × 55mm — about 120mm with the bracket — it drops into SFF builds, 1U racks and cramped mini-ITX cases where a full-height card simply won’t fit.
Every operating system already knows it. Windows, Windows Server, Linux, VMware, pfSense, OPNsense — native drivers, straight out of the box. No INF files, no forum digging. Plug it in and it’s there.
It doesn’t flake when it matters. The 82574 is a genuine server-grade controller, not a consumer-grade afterthought. Sustained transfers, minimal frame loss, no mystery disconnects. That’s exactly why the pfSense and OPNsense crowd keeps landing on this chip.
PXE and diskless boot supported — built for thin clients and diskless workstation deployments.
One honest note: the 82574 is popular enough to have been cloned. We sell genuine Intel only. Verify it yourself the moment you boot — it should identify as Intel in lspci or Device Manager.
One port. One job. Years of uptime.
