SFX 550 W Server Power Supply

The Lemincrash SFX650 delivers 550 W from an SFX form factor designed for compact server chassis. It carries 80 Plus Bronze certification and operates on a 110-220 V input range at 50/60 Hz. The unit ships new and includes only the power supply itself. Builders working in space-constrained rack or small-form-factor enclosures will find the footprint familiar.

Verify SFX Clearance And Modular Cabling

Confirm that your chassis accepts an SFX-sized unit and that the mounting holes align with your frame. The supply is fully modular, so plan which cables you need before assembly. Check that the 550 W ceiling covers every component in the build, especially high-draw GPUs or multiple drives. The part number shown in the confirmation image must match your requirement exactly.

1300 g Unit With Full Modular Connectors

At 1300 g the power supply adds minimal mass to a dense build. Full modular connectors mean unused cables stay out of the airflow path, simplifying routing in tight server bays. The bronze-rated efficiency target reduces waste heat under typical loads. No extra accessories are bundled, so cable kits or adapters must be sourced separately if the stock set falls short.

Questions about this item

Does the package include any cables or mounting hardware, or just the PSU itself?

The package contains the PSU only. Cables and mounting hardware are not included and must be sourced separately.

Should I choose the 550W or 650W label when my build needs 550W continuous power?

The unit delivers 550W maximum power. The 650W figure in the model name is a series identifier, not the rated output.

Will the 80 Plus Bronze rating still benefit me if my mains supply is 110V instead of 220V?

Yes. The PSU accepts 110–220V at 50/60Hz, so the Bronze efficiency certification applies across the full input range.
