tvONE 1RK-4RU-PSU – ONErack 4RU Standard PSU 250W
Product Overview
The tvONE 1RK-4RU-PSU is the standard 250W power supply unit for the ONErack 4RU chassis. It mounts inside the 4RU frame and provides centralized DC power to all connected module slots, replacing multiple individual wall wart adapters with a single managed power source. It is the PSU included standard with the 1RK-4RU-KIT and is also available separately for replacement or as an addition to the 1RK-4RU-BASIC-KIT.
Product Description
The 1RK-4RU-PSU delivers 250W of DC power to devices installed in the ONErack 4RU chassis. This is the chassis-specific designation of the standard ONErack PSU, ensuring the correct unit is ordered for the 4RU frame. It provides a significant improvement over individual wall wart adapters: centralized power delivery, consistent voltage, and reduced rack clutter from excess adapter cabling. The PSU mounts inside the ONErack 4RU chassis and connects to the chassis power bus via two locking rear outputs. A front power connector provides accessible servicing without requiring the PSU to be fully removed from the chassis. The front power output also supplies power to the optional ONErack Fan Cover accessory. While the standard 250W PSU is appropriate for most 4RU chassis deployments, integrators requiring higher power capacity or live PSU replacement should consider upgrading to the 1RK-4RU-PSU-2-HSWP (450W hot-swappable). The 1RK-4RU-PSU is a direct replacement for a failed or aging PSU in an existing 4RU installation, and the appropriate pairing PSU when the chassis is purchased via the 1RK-4RU-BASIC-KIT. Available from Creation Networks.

Frequently Asked Questions
Is the 1RK-4RU-PSU included with the ONErack 4RU Kit?
Yes. The 1RK-4RU-KIT (Standard Kit) ships with the 1RK-4RU-PSU pre-installed. The standalone PSU is for replacement use or for pairing with the 1RK-4RU-BASIC-KIT.
Can I upgrade from this PSU to the hot-swappable version?
