1400W ATX power supply for high-draw systems

This KHACHIMO unit delivers 1400W of continuous ATX power. It suits workstations and servers that run multiple GPUs or dense storage arrays. The S7506E-S and S7503E designations identify the same platform under different part codes. Each unit is tested before it ships.

Steady output under sustained load

The switching topology maintains regulated rails during long rendering or compute sessions. Protection circuits guard against over-voltage, over-current and short-circuit events without tripping on transient spikes. Thermal management keeps internal components within spec when the supply runs near its rated ceiling for hours. Builders who need redundant or hot-swap modules should look at dedicated server chassis instead.

Questions about this item

How much power does the 1400W unit draw when running continuously under load?

The PSR1400-A is rated for 1400 W output; actual AC draw will depend on system load and efficiency at that load.

Which motherboard power connectors must my board provide for the S7506E-S to work?

As an ATX supply it uses the standard 24-pin main and 4/8-pin CPU connectors — check your motherboard for matching sockets.
