High-wattage ATX 3.0 server PSU

The Lemincrash FM-1600W delivers 1600 W of continuous power through a fully modular ATX design. It targets dual-CPU server builds and high-end workstations that demand maximum headroom for multiple GPUs and expansion cards. The unit accepts 100-240 V input at 47-63 Hz for worldwide deployment.

Sustained load behaviour

A single 12 V connector supplies up to 600 W to PCIe 5.0 graphics cards without cable clutter. The 20+4 pin main connector and 25 A output rating support stable delivery during prolonged compute or rendering sessions. Fully modular cabling ensures only necessary leads are installed, reducing resistance and voltage drop under heavy demand.

Thermals, noise and power draw

A 140 mm hydraulic-bearing fan handles heat dissipation across the 185 x 150 x 85 mm chassis. The bearing design maintains consistent airflow while minimising mechanical noise during typical server operation. Universal input voltage allows efficient operation across global mains standards without manual switching.

Questions about this item

How loud does the 140 mm hydraulic-bearing fan get when the unit runs at 1600 W all day?

The 140 mm fan uses a hydraulic bearing for sustained heat dissipation, and the fully modular design lets you attach only the cables your build needs, reducing clutter and improving airflow.

Which cables come in the box so I know what I must already own to finish the build?

Only the AC power cord is included; the unit itself is fully modular so you supply every ATX 20+4 pin, CPU and PCIe cable your system requires.

Will the 12-pin connector that delivers 600 W for PCIe 5.0 cards work with the older GPU I plan to keep?

The 12-pin connector is rated for 600 W on PCIe 5.0 graphics cards; older GPUs that use 6+2 pin or 8-pin plugs will need the appropriate modular cables you provide yourself.
