Ruth's sister ST-200UAB-05E 200W power supply

This 200 watt unit fits 1U desktop and server chassis. It delivers +3.3V at 17A, +5V at 18A and +12V at 14A from a 100-240V input. Active PFC corrects the power factor. The non-modular design keeps all cables fixed inside the case.

Fixed cables with 20-pin and 4-pin connectors

A 20-pin main connector powers the motherboard while a 4-pin plug feeds the CPU. Two SATA ports supply drives without extra adapters. The 18 by 10 by 4 centimetre footprint matches standard 1U bays. Non-modular wiring reduces loose cables but limits routing flexibility.

200W output with 14A on the 12V rail

The +12V line provides 14 amps, which determines how many drives and expansion cards the supply can support. Builders needing more 12V current for additional GPUs or large drive arrays should choose a higher-rated unit.

Questions about this item

What does the 20-pin ATX connector on the ST-200UAB-05E limit in practice?

The 20-pin ATX connector delivers +3.3V at 17A, +5V at 18A and +12V at 14A, capping total output at 200W for compatible 1U systems.

What clearance does the 18 cm × 10 cm × 4 cm chassis of the ST-200UAB-05E require?

The unit fits a standard 1U rack slot measuring 18 cm long, 10 cm wide and 4 cm high, so verify your chassis has that exact internal space.

How do you connect the two SATA drives to the ST-200UAB-05E without a modular cable?

Because the supply is non-modular, plug the two fixed SATA power leads directly into each drive; the 4-pin CPU lead goes to the motherboard header.
