SFX 400W Fully Modular Server PSU

This Lemincrash SFX power supply delivers 400W of continuous power in a compact 125*110*63mm form factor. It carries 80 Plus Bronze certification and operates on a wide 110-230V input range at 47-63Hz. The fully modular cabling design lets you connect only the cables your build requires, reducing clutter and improving airflow inside tight server chassis.

Ideal for compact servers.

This unit suits administrators deploying space-constrained servers or workstations that need reliable, efficient power within the SFX footprint. The hydraulic-bearing fan aids heat dissipation in dense environments. Builders planning multi-GPU arrays, heavy overclocking, or systems that demand more than 400W should look at higher-capacity alternatives instead.

400W maximum output is the deciding spec

The single figure that determines fit is the 400W maximum power rating. Verify your complete system draw stays below this limit under full load. The 20+4Pin main connector and 12V connector support modern motherboards and graphics cards, but total available wattage remains the hard constraint for component selection.
