The MikroTik RB450Gx4 is a bare RouterBOARD — a quad-core ARM router board with 5× GbE, 1 GB RAM, hardware IPsec acceleration, and passive PoE-out on Ether5, supplied without an enclosure for custom deployments, embedded installs, or existing RB450/RB850 chassis upgrades.
**Quad-core IPQ-4019 ARM — hardware IPsec acceleration**
IPQ-4019 quad-core ARM 32-bit at 448–896 MHz auto-scales under load — 4 threads available to RouterOS for firewall, NAT, routing, VPN, and bandwidth management workloads. Hardware IPsec offload accelerates site-to-site VPN throughput beyond what a comparable software-only CPU delivers. 1 GB RAM handles large connection tracking tables and complex firewall rule sets for SMB and small ISP edge deployments.
**512 MB NAND + microSD — expanded storage for logging and backup**
512 MB NAND provides ample space for RouterOS v7 and configuration. MicroSD slot accepts standard cards for extended data logging, configuration backups, and Dude network monitoring server storage without USB adapters.
**3 power inputs — 2× DC jack + PoE-in 802.3af/at**
Two DC jacks accept 10–57V — dual feed redundancy without external failover hardware. PoE-in accepts 802.3af/at or passive 12–57V as a third input option. Passive PoE-out on Ether5 (500 mA low and high voltage) powers a downstream MikroTik wAP, mAP, or SXT without a separate injector.
**No enclosure — compatible with RB450 and RB850 series enclosures**
Supplied as a bare board — identical form factor (90 × 116 mm) to the RB850 and RB450 series. Fits existing enclosures from those product lines. Use the RB450Gx4 as a drop-in board upgrade or build into a custom chassis.
**Canadian market note:** CE, EAC, RoHS only — no FCC, no IC. Wired router board, no wireless transmitter — no ISED wireless type approval required.
