ATX 400W server power supply

The Lemincrash ATX 400W unit delivers 400W of continuous power through a 20+4Pin main connector and a 12V connector for modern graphics cards and motherboards. It operates on 110-230V input at 50/60 Hz with a 5A input current rating. A 120mm hydraulic-bearing fan provides cooling while integrated RGB lighting activates during operation.

ATX form factor limits

The standard ATX dimensions of 150mm by 140mm by 85mm fit typical server and desktop chassis designed for this form factor. The single 120mm fan handles thermal loads within the 400W envelope but offers no redundancy for mission-critical uptime. Input voltage auto-ranging covers 110V to 230V without a manual switch.

400W capacity headroom

The 3.3V rail supplies 12A for a maximum of 40W, supporting peripheral and logic loads on compatible boards. Total output of 400W suits entry-level builds with modest CPU and single-GPU configurations. Systems requiring multiple high-end GPUs, heavy overclocking or redundant power paths will exceed the practical headroom of this unit.

Questions about this item

Should I pick the 3.3V 12A rail or the 12V connector for my build?

The 3.3V rail delivers 40W for legacy components while the 12V connector powers modern graphics cards and motherboards; both are present on the same unit.

What does the 400W rating actually deliver inside my case?

It supplies up to 400W total across all rails with a 120mm hydraulic-bearing fan keeping temperatures down under load.

Is the 20+4Pin ATX connector limited to 110V or 230V input?

The supply accepts 110-230V at 50/60Hz so the single 20+4Pin connector works worldwide without switching.
