350 W 1U Flex ATX power supply

This 350 W 1U Flex ATX power supply fits slim desktop and server chassis that accept the Flex form factor. It delivers a single 350 W rail through a fixed, non-modular cable set. The unit is aimed at system integrators and hobbyists building compact ITX or 1U rackmount machines.

Sustained-load behaviour

Active power-factor correction maintains a stable draw across the 164 V to 264 V input range during continuous operation. A single internal fan provides airflow while the supply runs at full rated output. The fixed cable loom means all conductors are always present, so voltage regulation stays consistent regardless of which connectors are populated.

Deciding specification

The 20 + 4-pin ATX main connector and single 4-pin CPU power connector define motherboard compatibility. Two SATA power plugs and two D-type peripheral plugs limit the number of drives and accessories that can be powered simultaneously. Builders needing more than two SATA devices or an 8-pin CPU connector should choose a different unit.
