TF400 350W Flex ATX unit
This 350W Flex ATX power supply fits 1U and small-form-factor chassis such as POS and all-in-one systems. It delivers a maximum output of 450W with 90% efficiency and active PFC. The unit is fully modular and built for 220V mains only.
Full modular cabling and connectors
All cables detach from the unit, leaving only the 20+4 pin motherboard lead, an 8 pin CPU connector, two 6 pin PCIe leads and two SATA plugs inside the case. This reduces clutter in tight enclosures and eases assembly or service work.
Temperature-controlled fan and 220V input
A PWM fan adjusts speed to load, keeping acoustic output low during typical operation. The supply accepts 164V to 264V AC and does not support 110V regions. Continuous rated power is 350W across the 3.3V, 5V and 12V rails.

Questions about this item
What does the 20+4 pin ATX interface limit in practice?
The 20+4 pin ATX connector supplies up to 350 W continuous and 450 W peak across the 3.3 V, 5 V and 12 V rails.
What physical space does the 170×40×83 mm Flex ITX form factor need?
It fits a standard 1U Flex ITX bay measuring 170 mm deep, 40 mm high and 83 mm wide.
How is the full-modular unit installed, and which step is often missed?
Mount the 1U chassis, plug only the required 20+4 pin, 8-pin CPU, two 6-pin GPU and two SATA cables, then verify the 164-264 V AC input matches your mains supply.
