Lenovo 4XC1K80847 network card Internal Ethernet 1000 Mbit/s

Product Overview

AI-generated summary

At ~£126.40 ex‑VAT for a Lenovo-branded internal 1GbE NIC, this is one of those “only makes sense if you’re already deep in Lenovo parts” purchases. If it’s going into a compatible Lenovo server/workstation and you want a straightforward, low-drama replacement, it’s a fair price. In day-to-day use, a decent 1GbE adapter is mostly invisible—stable drivers, predictable performance, and you don’t have to babysit it the way you sometimes do with off-brand gear.

I’d only avoid it if you’re buying purely on price for a generic PC/server chassis, because you’ll want to be sure it matches the exact form factor and platform compatibility (Lenovo models can be picky). Also, if you’re planning any meaningful uplift—virtualisation-heavy traffic, storage over Ethernet, or lots of east-west traffic—this is still 1GbE, so it won’t be your bottleneck relief; you’d look at faster networking instead. Bottom line: buy it when you need a like-for-like Lenovo replacement and want reliability. Don’t buy it as a “network upgrade” for modern workloads where 10GbE (or more) is where the real value shows up.
