T.F.SKYWINDINTL 350W Flex ATX 1U Server Power Supply

Compact 1U Server Power Supply

This 350 W Flex ATX unit fits 1U rack enclosures and small all-in-one chassis where depth is limited to 150 mm. It targets system builders who need a replacement PSU for cash-register servers or thin industrial PCs. The forced-air design relies on a single 40 mm double ball-bearing fan to move heat through the narrow profile. Buyers who need redundant or hot-swap modules cannot use this form factor.

350 W on the +12 V Rail

The +12 V line delivers 20 A, which is the limiting factor for modern CPU and GPU loads in this class. Combined 3.3 V and 5 V rails are rated at 12 A each, while minor rails provide -12 V and +5 VSB. The 20+4 pin main connector, one 4-pin 12 V (P4), two SATA, two 4-pin Molex and one 6-pin peripheral cover typical 1U server backplanes. Systems requiring more than 20 A on +12 V must choose a higher-wattage design.

Thermals Noise and Power Draw

Universal 90–264 V input allows operation on 110 V or 220 V mains without a voltage switch. The 80 Plus series rating indicates baseline efficiency under typical server loads. A single 40 mm fan runs continuously to cool the 150 mm x 81.5 mm x 40.5 mm enclosure, producing audible airflow noise in quiet rooms. Power draw at the wall follows the load; no fan-stop or semi-passive mode is specified.
