Compact 350W Flex ATX Power Supply

The Ruth's sister 350WXH is a 1U form-factor unit rated at 350W continuous with a 400W peak capability. It targets small-chassis desktop and server builds that require a full-modular cable set. The 20+4 pin main connector and CPU, PCIe and SATA leads are all detachable, reducing clutter in Mini-ITX cases.

Sustained Load Behaviour

Active PFC and a single silent fan maintain stable output across the 90V-264V input range. The +12V rail delivers up to 22A while the +3.3V and +5V rails supply 20A and 30A respectively. Over-voltage, under-voltage, overload, over-current and short-circuit protections engage automatically during prolonged high-demand operation.

Interface Practical Limits

The modular interface uses a 14-pin motherboard connector fed by a 20+4 pin cable, a 4+4 pin CPU cable, one 6-to-2+6 pin PCIe cable and a daisy-chain SATA/IDE lead with two SATA plugs. Cable lengths are fixed at 47cm, 53cm, 63cm and 53cm plus three 17cm segments respectively, limiting routing options in larger enclosures.

Questions about this item

How much heat and noise does the 350W single silent fan produce under continuous load?

The single silent fan cools the 350 W rated output while active protections manage voltage and current limits.

Which motherboard and GPU connectors must my build already provide for the 20+4Pin interface and 6-pin cables?

The set includes a 20+4 pin to 14 pin cable, a 4 pin to 4+4 pin CPU cable, and a 6 pin to 2+6 pin GPU cable.

Will the 4-pin CPU connector and SATA leads work with older boards and drives I want to keep?

The 4-pin CPU lead and the daisy-chained SATA plus IDE cable support legacy motherboards and storage devices directly.
