The iStarUSA TC-300R8 is a redundant server power supply with two 300 W modules and a 20+4-pin main connector, suited to server builders whose systems require this power-supply format and configuration.
Recommended For
- Operators maintaining a compatible rackmount server who need a like-for-like replacement for the TC-300R8’s PS/2-size redundant supply.
- Small-server administrators who prioritize continued operation through a power-supply-module failure and need hot-swappable, redundant power in a supported chassis.
- Administrators restoring a legacy server whose motherboard and workload fit the supply’s listed ATX/EPS connections and 300 W output.
Real-World Use Scenarios
- Running a server that needs to stay available: if one power module fails, the redundant design is intended to let the other continue supplying power, reducing the chance of an unexpected shutdown.
- Powering a file server or disk-array system: the redundant supply is aimed at systems where keeping storage available matters more than relying on a single power module.
- Replacing a failed module during maintenance: in a compatible redundant-power setup, the manual describes identifying the faulty module and replacing it, helping avoid a full system shutdown during the repair.
- Refreshing an older server build: its PS/2-size design and 20+4-pin main connector may suit a compatible legacy server chassis, so users should check the chassis fit and connector requirements before choosing it.
