Lemincrash 500W ATX Server PSU

This Lemincrash 500W unit is an ATX server power supply rated for 500W maximum output with 80 Plus certification. It accepts a universal 100-240V input at 50/60 Hz and uses a single 120 mm fan for cooling. The 20+4Pin main connector fits standard ATX motherboards. It ships new without a power cord.

Who this suits and who should look elsewhere

Builders assembling a standard ATX server or workstation needing 500W of reliable power with six protection circuits will find this unit suitable. The intelligent temperature control adjusts fan speed automatically for quieter operation. Systems requiring more than 500W, redundant power modules, or a bundled AC cable should look at other options.

Capacity and headroom

The 500W maximum rating comfortably handles typical single-CPU server boards with moderate GPU or storage counts. The 12V rail delivers the bulk of power for modern components. High-density multi-GPU configurations or dual-socket platforms with heavy peripheral loads will exceed the available headroom.

Questions about this item

What motherboard power connector must my board provide for the 20+4-pin main cable?

Your motherboard needs a standard 24-pin ATX socket; the 20+4-pin cable splits to fit either 20-pin or 24-pin headers.

Will the 100-240 V input range let me keep my existing 110 V or 220 V mains wiring?

Yes, the unit accepts 100-240 V at 50/60 Hz, so it works on both 110 V and 220 V circuits without any switch.

How can I confirm the 120 mm fan is responding to load after installation?

The intelligent temperature-control circuit varies fan speed with internal heat; you should hear the 120 mm fan spin up as power draw rises.
