Learn more about the AMD Ryzen™ 3 4300U processor & storage options

The CSL Narrow Box 4300U is powered by the AMD Ryzen™ 3 4300U mobile processor from the "Renoir" generation.

More on memory upgrades, Dual M.2 slots & connectivity

The CSL Narrow Box 4300U stands out for its high expandability within a compact footprint. Its MP15A motherboard provides two SO-DIMM slots for DDR4 memory (up to 3200 MHz, max. 32 GB), unlocking maximum dual-channel bandwidth for the integrated Radeon RX Vega 5 GPU.

For storage, two M.2 slots are available: The primary M.2 2280 slot is ideal for fast PCIe NVMe system drives, while the secondary M.2 2242 slot accommodates extra storage capacity for files and backups.

Network Connectivity and Expansion

Connect effortlessly via high-speed wireless Wi-Fi 6 (Realtek 8851BE AX900 module with Bluetooth 5.4) or wired Realtek Gigabit Ethernet. Multiple USB ports make it easy to attach a full range of desktop peripherals.

Applications

Versatile use cases for the CSL Narrow Box 4300U

This Mini PC handles diverse workloads silently and with minimal space requirements.

Home Office & Business

Ideal for office productivity, email management, ERP systems, and video calls. Triple-monitor support (2× HDMI 2.0, 1× USB-C with 4K@60Hz) ensures a comprehensive workflow overview.

Casual & eSports Gaming

Powered by integrated AMD Radeon™ RX Vega 5 graphics, this Mini PC easily handles casual gaming. Popular eSports titles like League of Legends, Valorant, or CS2 run smoothly at tailored settings.

Media Center & 4K Streaming

Use this Mini PC as a discrete living room media hub. Integrated AMD Radeon™ RX Vega 5 graphics delivers smooth 4K movie playback and streaming at 60 FPS with 5.1 HD audio.

Smart Home & Home Server

With a low 15W sustained TDP, the AMD Ryzen™ 3 4300U processor excels as an energy-efficient Home Assistant central node, file server, or print server under Windows 11.

Digital Signage & Point-of-Sale

Featuring a compact chassis, PXE Boot, Wake-on-Power, and Wake-on-LAN, the Narrow Box 4300U integrates smoothly into commercial IT environments.

Which storage configuration best suits your setup?

For standard office workloads and web browsing, an entry-level setup with an M.2 SSD and 8 to 16 GB RAM is perfectly sufficient. For handling larger datasets, eSports titles, or resource-heavy applications, we recommend configuring 32 GB RAM with extra storage installed in the secondary M.2 2242 slot.

Commercial clients and IT administrators deploying digital signage or kiosk solutions will benefit from the stability of the AMD platform alongside BIOS-driven remote features like Wake-on-LAN (WoL), Wake-on-Power (WoP), and PXE Boot.
