Ruth's sister TF350W 350W Flex ATX PSU

The Ruth's sister TF350W is a full-modular Flex ATX power supply delivering 350W continuous output at 40 rated operating temperature. It targets builders assembling compact desktop or server systems that require the Flex ATX form factor and a single +12V rail design. Japanese main condensers and active PFC support 24/7 operation in small chassis.

Check Flex ATX clearance and connector needs

Verify that your chassis accepts the Flex ATX form factor and that the 20+4 pin main connector matches your motherboard. The unit provides an 8-pin CPU connector, two 6-pin graphics connectors, two SATA ports and two D-type bus connectors. Ensure your components do not demand additional PCIe or peripheral connectors beyond this allocation.

Full-modular cables reduce internal clutter

The full-modular design lets you attach only the cables your build requires, improving airflow in tight 1U or mini-ITX enclosures. A sealed housing resists moisture and dust ingress. The black painted shell adds durability without affecting electrical performance.

Questions about this item

Does the TF350W come with all cables attached or are any sold separately?

The unit is fully modular so only the cables required for the build need to be connected; no extra cables are included in the box.

The specs list 350 W continuous and 450 W peak — which rating should I use for a 24/7 server?

Design the system around the 350 W continuous figure at 40 °C; the 450 W value is a short-term peak, not a sustained load rating.

What does the single +12 V rail mean when the supply is installed in a desktop?

All 12 V components — CPU, graphics cards and drives — draw from one combined rail, simplifying load balancing and removing multi-rail limits.
