Buying Guide: Key Considerations for Selecting a Rack-Mount PDU
- Outlets and layout: Count, front vs rear outlets, and spacing influence device compatibility and cable management. Larger racks may need more front outlets; consider a mix of front/rear for accessibility.

- Mounting options: 1U horizontal PDUs save space; vertical mounting options are useful for certain rack configurations. Check size and mounting hardware compatibility with your rack.
- Surge and protection features: Surge protection, circuit breakers, and indicator LEDs help protect equipment and provide quick status checks.
- Management and monitoring: Basic PDUs offer power distribution; managed PDUs provide port-level monitoring, alarms, and network access. Choose based on how much visibility you need.
- Certifications and safety: UL or equivalent certifications indicate compliance with electrical safety standards. This matters for data-center-grade deployments.
