Compact 350W Flex ATX 1U PSU

This 350W Flex ATX 1U power supply fits all-in-one machines and 1U server chassis. It delivers 350 watts across a 90-264V input range with active PFC. The non-modular design includes a fixed 24-pin ATX connector, a 4-pin CPU plug, two SATA ports and a 6-pin graphics connector. It targets builders deploying compact desktop or cash-register servers.

80 PLUS Gold efficiency and thermal profile

Gold-rated efficiency reduces waste heat and keeps power draw lower at typical loads. The 1U form factor relies on a small internal fan that spins faster under load, so audible noise rises with sustained output. Input voltage auto-ranges from 90V to 264V, covering 110V and 220V mains without a switch.

Fixed cable bundle simplifies small builds

The non-modular loom supplies exactly the connectors listed: 24-pin motherboard, 4-pin CPU, two SATA drives and one 6-pin GPU plug. No extra cables remain to route in a tight 1U enclosure. Builds needing more SATA devices, an 8-pin GPU connector or modular cable management cannot use this unit.

Questions about this item

How do I install the 24-pin and 4-pin CPU connectors on this non-modular 350W Flex ATX 1U PSU, and which step do people get wrong?

Route the fixed 24-pin motherboard cable and the 4-pin CPU cable into the 1U chassis before securing the PSU; the common mistake is tightening the PSU screws first, which traps the stiff cables and blocks the CPU connector.

What maintenance or replacement will the active PFC Gold-rated 350W Flex ATX 1U PSU need later?

Expect to clean dust from the intake fan and heatsink every 6–12 months; the internal fan is the only moving part and will eventually require replacement when bearing noise appears.

What limit appears first on this 350W Flex ATX 1U PSU under sustained 90–264V input load?

The 350 W continuous power ceiling is reached before voltage regulation or thermal protection activates, so total system draw must stay below that figure.
