About the MikroTik RB750GR3 hEX Router (5-port Gigabit)
The MikroTik RB750GR3 hEX Router is engineered as a compact, fanless routing solution for enterprise branch offices, retail locations, and distributed network environments where passive cooling and minimal power consumption are operational priorities. This 5-port Gigabit device delivers robust Layer 3 routing and security capabilities without active cooling, making it suitable for temperature-variable deployments. Network engineers and IT procurement teams evaluating cost-effective edge routing will find the RB750GR3 particularly valuable for its dense feature set within a small footprint.
Built on MikroTik's proven RouterOS Level 4 platform, the RB750GR3 combines an 880 MHz dual-core MIPS processor with 256 MB DDR3 RAM and 16 MB NAND flash to support enterprise-class routing protocols including BGP, OSPF, MPLS, and IPsec. The device accepts input voltage from 8–30 V DC with PoE-in capability on port 1 (802.3af/at compatible), reducing deployment infrastructure requirements. At idle, power consumption is approximately 4 W, rising to approximately 7 W under maximum load—well-suited for remote or power-constrained installations. The included 24 V 0.8 A power adapter ensures out-of-box readiness. RouterOS Level 4 licensing enables advanced features such as firewall rules, NAT, OpenVPN, VLANs (802.1Q), and HTB/HFSC/PCQ queuing disciplines, alongside a comprehensive scripting API for custom automation. The RB750GR3 operates reliably across −40 °C to +70 °C, and its lightweight 140 g chassis supports both desktop and wall-mounted deployments in compact network closets or outdoor enclosures.
