Supersuperuncle YQ-400S 250W SFX Server PSU

The Supersuperuncle YQ-400S is a 250W SFX server power supply built for compact desktop chassis. It targets builders who need a small-form-factor unit to run low-power server or workstation hardware. The SFX footprint allows installation in tight enclosures where standard ATX units will not fit. This unit delivers the rated output for modest component configurations.

Practical limits of the SFX form factor

The SFX form factor restricts physical space for larger cooling solutions and higher-wattage designs. A 250W ceiling limits support for power-hungry CPUs, multiple GPUs or large drive arrays. Builders who need more headroom for future upgrades or high-end graphics cards cannot rely on this capacity. Systems requiring redundant power or higher continuous loads are not suited to this unit.
