Designed to unleash the full potential of modern SSDs and peripherals with up to 800 MB/s transfer speeds, it installs easily via PCIe x4 with plug-and-play convenience and broad OS compatibility, breathing new life into older machines with legacy USB interfaces. ## Description Equipped with SSDs, the fastest USB drives you can buy today are capable of 800 MB/s data transfers, and many are bus-powered. Most desktop computers (even new models) include generations-old USB interfaces that will throttle that performance and may not offer adequate power to allow bus-powered drives to operate. Install Sonnet’s Allegro USB-C 4-Port PCIe card into a PCIe slot of your Mac Pro, Windows, or Linux computer, or Thunderbolt Expansion System, and support fast USB drives at maximum performance. Review: Totally transformed my 2009 Mac Pro Tower - a totally must-have item. - Over the past few years I have completely customised my beloved old Mac Pro Tower by adding a faster CPU, more RAM, a PCI SSD and this little beauty from Sonnet. To be condemned to USB 2 ports in this day and age is pure torture. Luckily the good people at Sonnet have come to the rescue with this 4-port USB 3.1 gen2 PCIe card. Installing it was literally plug and play. Now I can attach any modern, high-speed, peripherals like an external USB-C (3.1 gen2) M.2 SSD drive and get very decent speeds. The screen grabs below are from a Sabrent 1TB M.2 NVMe inside a Sabrent enclosure. This PCIe card by Sonnet has completely transformed my computer's abilities. Very impressed. Review: Great PnP solution for Macs - Great. Has given my Mac Pro 5.1 a new lease of life. Installed with zero problems, no drivers and no extra power cables to hook up. The whole process took about 3 minutes. ## Features - USB-C 4-port PCIe Card - Package Dimensions: 3.6 L x 21.6 H x 14.1 W (centimeters) - Model Number:USB3C-4PM-E - Item package quantity: 1.0 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07L8KCQPT | | Best Sellers Rank | 77,953 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 99 in USB Port Cards | | Box Contents | SoNNeT USB3C-4PM-E | | Brand | SoNNeT | | Brand Name | SoNNeT | | Compatible Devices | Personal Computer, Laptop, SSD, HD, SSD RAID, USB 3.2 Gen 1, Gen 2 & 2x2, USB 3.1 Gen 1 & 2, USB 3.0, 2.0 and 1.1 | | Compatible devices | Personal Computer, Laptop, SSD, HD, SSD RAID, USB 3.2 Gen 1, Gen 2 & 2x2, USB 3.1 Gen 1 & 2, USB 3.0, 2.0 and 1.1 Compatible devices Personal Computer, Laptop, SSD, HD, SSD RAID, USB 3.2 Gen 1, Gen 2 & 2x2, USB 3.1 Gen 1 & 2, USB 3.0, 2.0 and 1.1 See more | | Customer Reviews | 4.1 out of 5 stars 145 Reviews | | Global Trade Identification Number | 00732311012648 | | Hardware Interface | PCI Express x4 | | Hardware interface | PCI Express x4 | | Item Type Name | Sonnet Allegro USB-C 4-Port PCIe Card | | Item Weight | 68 Grams | | Item weight | 68 Grams | | Manufacturer | SONNET TECHNOLOGIES | | Manufacturer Part Number | USB3C-4PM-E | | Model Number | USB3C-4PM-E | | Operating System | Windows | | Product Warranty | 2 Years | | Style | Single | | Style Name | Single | | UPC | 732311012648 | ## Product Details - **Brand:** Sonnet - **Hardware Interface:** PCI Express x4 - **Style:** Classic - **Item Weight:** 68 Grams - **Compatible Devices:** Personal Computer, Laptop, SSD, HD, SSD RAID, USB 3.2 Gen 1, Gen 2 & 2x2, USB 3.1 Gen 1 & 2, USB 3.0, 2.0 and 1.1 ## Images ![Allegro USB-C 4-port PCIe Card [Thunderbolt compatible] - Image 1](https://m.media-amazon.com/images/I/81fWgSijteL.jpg) ![Allegro USB-C 4-port PCIe Card [Thunderbolt compatible] - Image 2](https://m.media-amazon.com/images/I/71uw0tgteCL.jpg) ![Allegro USB-C 4-port PCIe Card [Thunderbolt compatible] - Image 3](https://m.media-amazon.com/images/I/71K7HeR57uL.jpg) ![Allegro USB-C 4-port PCIe Card [Thunderbolt compatible] - Image 4](https://m.media-amazon.com/images/I/81Am9RmAPaL.jpg) ## Questions & Answers **Q: Are they all thunderbolt 3 ports?** A: No, they are 10Gb/s USB 3.1 gen 2 ports.

Installed with zero problems, no drivers and no extra power cables to hook up. The whole process took about 3 minutes. ### ⭐⭐⭐ Now on the 3rd card in a year *by M***N on 22 December 2020* Now purchased my third card as the previous two failed; the first within a week, the second in 49 weeks. Two of the four ports fail to communicate or recognise a USB device when inserted. When working the card works great on my MacPro. ## Frequently Bought Together - Sonnet Allegro USB-C 4-Port PCIe Card - Sonnet Allegro Pro USB 3.2 Type A PCIe Card (Four SuperSpeed 10Gbps USB Connectors) - Allegro Type A USB 3.2 | 3.0 PCIe 4-Port PCIe Card (Mac and Windows Compatible) --- ## 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.tn/products/115025039-allegro-usb-c-4-port-pcie-card-thunderbolt-compatible](https://www.desertcart.tn/products/115025039-allegro-usb-c-4-port-pcie-card-thunderbolt-compatible) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-13*
