Juniper JPSU-450W-AC 450W AC Power Supply Unit | Enterprise PSU

Keep supported Juniper hardware running with a replacement power supply designed for the platform it serves. The Juniper JPSU-450W-AC delivers 450 W of AC power in a form factor intended for direct system integration, helping preserve uptime during maintenance, repair, or component replacement. For infrastructure teams, the value is in fit and predictability. A matched PSU reduces the risk of compatibility issues that can come with generic alternatives and helps maintain the electrical characteristics the chassis expects. That matters in production environments where power stability is part of the service contract, not an afterthought. This unit is suited to organizations that keep spare parts on hand for rapid swap-out and controlled recovery. It supports a practical maintenance strategy: replace failed components quickly, restore normal operation, and avoid extending downtime while sourcing the correct part. When the cost of interruption is higher than the cost of the component, a proper OEM power supply is the safer choice. The JPSU-450W-AC is built for that standard.
