2.5Gbps PCIe Network Card

The DERAPID RTL8125 adds a single 2.5Gbps RJ45 port to any desktop or NAS through a PCI Express x1 slot. It targets users who need faster wired throughput than standard Gigabit without replacing their existing router or switch.

Low-profile and full-height brackets included

Two mounting brackets ship in the box so the card fits both standard towers and slim small-form-factor cases. The Realtek RTL8125 controller provides backward compatibility with 100Mbps and 1Gbps networks while delivering up to 2500Mbps on supported links.

PCIe x1 slot required

Installation needs an open PCI Express x1, x4, x8 or x16 slot; legacy PCI slots are not supported. Windows 7 through 11 and Linux are supported, but the card will not function in systems lacking a compatible PCIe slot.

Preguntas sobre este artículo

What maintenance or replacement will the RTL8125 card need later?

The card uses a passive heatsink with no moving parts, so no routine maintenance is required. The only replacement would be the card itself if the controller or RJ45 port fails.

What limit shows up first under sustained heavy network load?

The 2500Mbps data-transfer ceiling of the RTL8125 controller is the first hard limit reached during continuous high-throughput transfers.

How much heat or power does the card draw when running all day?

The supplier notes low power consumption and a built-in high-efficiency heatsink for stable cooling during long-time heavy network load.
