1-Port 2.5Gb Ethernet Network Card, with Realtek RTL8125B Chip | 100M/1000M/2.5G Ethernet NIC, Single RJ-45 Port, PCIe2.1, X1, Support Windows Server/Vmware ect., Model: RTL8125-2.5G-1T-X1

Was looking for a 2.5gbe NIC that would work fine with Windows Server 2019 due to the 2 NICs built onto the motherboard not being compatible with Windows Server family (thanks Intel for purposely doing this so users are pushed towards proper server platforms instead of using a consumer one). The Realtek chipset used on this NIC installed without any hassle once got the drivers from Realtek’s global website. granted you will lose available PCIe lanes so may not be for someone that wants to keep 16 lanes for their GPU & multiple NVMe drives on a gaming rig, but general usage overheads are low and no worse than an onboard NIC (a lot of the cheaper NICs rely on software & the CPU to control traffic etc but this seems like a true hardware controlled NIC). Doesn’t seem to slow down under load either which a lot of cheaper cards can do as the controller gets hot, but this shouldn’t be a problem if got sufficient cooling in the case.Very happy with the performance of this NIC and will be buying more of them when required to either upgrade from Gigabit to 2.5gbe connectivity or replace a failed onboard NIC.

I always feel NICS are overpriced but this was the cheapest that I could find that actually looked reliable. And it has been. A year in, it's been working away without complaint and I've been plenty happy with it. There's not really much to add - you know what it is and what it's rated at. All I can say is that it's been able to work well and I've had no driver or other issues with it on Linux or Windows. I'll be happy to just use Gtek for any future NICs I need and if they have a 10Gb when I need that, will probably buy from them.With a network card, the main thing you want is for it to work and keep working. This does.

Easy to install, works really well and good value for money, what's not to like!Used in UnRaid server with 'RTL8125 Drivers' plugin and works flawlessly at 2.5gb/s

Ordered this as I recently upgraded to 5GB FTTH, while i am slowly moving to 10gb networking in my home 2.5 is perfect for what i need at the moment. The card came well packed, in an antistatic bag and seems well built, also comes with two adapters depending on your style of case. it was compatible with my pc and the drivers downloaded instantly no messy setup , as you can see from the speed tests it functions as should , note i was uploading and downloading a lot of files during itOverall i would recommend it

Have been using this for months now and perfect….. if you want to upgrade your current 1GB but don’t want the expense of 10GB then this is the perfect choice….

Works great plug and play.

Given my PC a 20x speed boost on backups to NAS

Perfetta per 2.5Gb. Chip riconosciuto da Windows

Super Teil - läuft auf Anhieb auch unter Linux.

Réseau ethernet ok.Mettre le driver Realtek à jour depuis le site

Installata per poter sfruttare la FTTH a 2.5 gbps teorici, funziona alla grande e su WIndows 10 non richiede driver aggiuntivi (superati i 2gbps reali). Arriva con la staffa piccola montata, quindi se avete un case standard, dovete montare la staffa metallica normale prima di poterla installare nel pc.

Ich verwende die Netzwerkekarte in meinen beiden Hypervisorservern mit verge.io (Linux) als Hypervisor mit einem 2,5G Switch als Core für Storage und Management. Läuft hervorragend. Das System läuft mit diesen beiden Netzwerkkarten erstaunlich schnell.
