It supports various PCIe slots and is compatible with multiple operating systems, making it a versatile choice for both gamers and professionals. The card comes with a low-profile bracket for easy installation in compact cases and is backed by a 3-year warranty. ## Description Provides 2.5 Gigabit Ethernet connectivity to Mac Pro towers and Windows PCs. Simple way to add or expand 2.5 Gigabit Ethernet connectivity to any compatible computer. It is suitable for multiple market segments and emerging applications, such as desktop, mobile, workstation, server, communications platforms, and embedded applications. Review: This upgrade to 2.5gig Ethernet is easy to install into a PCIe slot and drivers are included on the supplied mini CD. Many drivers are included including Windows 11, 10, Mac and Linux. Full speed is achieved using Cat 6 wire. Both full form and small form factor hardware included - easy to change out. Ethernet socket has two LED indicators for link and speed which is good since other cards may not have these indicators or have holes to see through to an LED on the inside surface of the card. The Realtek chip and the software may be able to go to 10gig in the future since there is some references in drivers and other information of the system. Maybe a firmware update in the future for this? Overall, this is a great product and very reasonable in price and support. Review: Acabo de instalar la tarjeta de red, si costo trabajo para que mi tarjeta madre la reconociera, aunque al ser pci, y puedes conectarla en los puertos pci-e 16x, posiblemente mi tarjeta no la reconoce de este modo, y fue necesario colocarla en los pci. con eso la detecto windows sin problemas, ya solo busque el driver directo del fabricante del chipset, el cual es Realtek, y permitió que funcionara un poco mejor. A comparación de mis anteriores test con el conector de red de la tarjeta madre, si varia la velocidad de internet, pero puede que con el tiempo se ajuste y me de mejores resultados. la primera foto es del antes, y la segunda con la tarjeta ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07RF4SZ8R | | Best Sellers Rank | #136,767 in Computers ( See Top 100 in Computers ) #393 in Network Cards | | Customer reviews | 4.4 4.4 out of 5 stars (257) | | Item model number | SI-PEX24059 | | Label | I/O Crest | | Manufacturer | I/O Crest | | Product Dimensions | 10.92 x 1.27 x 13.97 cm; 90.72 g | ## Product Details - **Brand:** IO CREST - **Hardware Interface:** Ethernet, PCI, PCI Express x1 - **Color:** multicolor - **Compatible Devices:** Desktop - **Product Dimensions:** 4.3"L x 0.5"W x 5.5"H - **Data Link Protocol:** IEEE 802.3 - **Data Transfer Rate:** 2.5 Gigabits Per Second - **Item Weight:** 0.2 Pounds - **UPC:** 857426008260 - **Global Trade Identification Number:** 00857426008260 ## Images ![IO Crest 2.5 Gigabit Ethernet PCI Express PCI-E Network Interface Card 10/100/1000/25000 Mbps RJ45 LAN SI-PEX24059 - Image 1](https://m.media-amazon.com/images/I/71lsMMrdhqL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***R on 12 January 2024* This upgrade to 2.5gig Ethernet is easy to install into a PCIe slot and drivers are included on the supplied mini CD.

Hardware installation was easy and took 10 minutes, and Windows 10 installed a driver for it so it worked straight away. However I was getting 280-odd MB/s incoming, but only 170-ish outgoing. So I installed the driver on the included CD (Realtek 8125 chipset) and that got full speed in both directions. So far seems like a great, economic way to upgrade. ## Frequently Bought Together - IO CREST 2.5 Gigabit Ethernet PCI Express PCI-E Network Interface Card 10/100/1000/25000 Mbps RJ45 LAN SI-PEX24059 - TP-Link 2.5GB PCIe Network Card (TX201) – PCIe to 2.5 Gigabit Ethernet Network Adapter, Supports Windows 11/10/8.1/8/7, Win Server 2022/2019/2016, Linux - Cable Matters 10Gbps Snagless Shielded Cat 6A Ethernet Cable - 14ft, Cat 6A Cable, Cat6A Cord, Ethernet Cord, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/263548261-io-crest-2-5-gigabit-ethernet-pci-express-pci-e](https://www.desertcart.ec/products/263548261-io-crest-2-5-gigabit-ethernet-pci-express-pci-e) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-04-22*
