Server Redundant Power Supply

The iStarUSA IS-2000RH1UP is a 2000W redundant server power supply with a 24Pin main connector. It fits a 1U form factor and accepts 100-240V universal input. Active PFC and industrial Japanese components rated for 40 degrees temperature support continuous operation. Automatic fan thermal control manages cooling noise.

Suits High-Availability Servers

This unit suits rack servers that require N+1 redundancy to maintain uptime during a module failure. The 24Pin connector and -5V rail provide backward compatibility with older motherboards. Builders needing a single non-redundant supply or a different main connector pinout should look elsewhere.

2000W Redundant Capacity Decides Fit

The 2000W redundant rating is the specification that determines whether this supply meets the load and availability target. Efficiency reaches 75% at full load with MTBF exceeding 100000 hours. Protections include OPP, OVP, OCP and SCP. Remote sensors monitor +5V and +3.3V rails with power failure alarm signals.

Questions about this item

At 2000 W continuous draw, what is the first thermal or electrical limit the unit hits?

The supply is rated for 2000 W maximum power with over-power protection that trips if that limit is exceeded.

How loud does the fan get and how much waste heat appears during all-day operation?

Automatic fan thermal control adjusts speed based on internal temperature; efficiency is 75% at full load, so heat output scales with actual power drawn.

Which existing server chassis and backplane connectors are required for this 24-pin redundant module to function?

The unit uses a 24-pin main connector and an industrial DIN connector; it fits 1U redundant bays that accept those interfaces.
