High-output ATX power supply

The KHACHIMO ZXD1500 V5.6 delivers 1600W of continuous power in a standard ATX form factor. It is built for workstations and high-end desktops that draw sustained heavy loads from multiple GPUs or dense storage arrays. The unit carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion for clean output.

Practical limits of the ATX standard

ATX power supplies share fixed physical dimensions and connector layouts that determine case compatibility and cable reach. The 80 PLUS Gold rating guarantees at least 80 percent efficiency at typical loads, which reduces waste heat but does not change the maximum power the form factor can safely distribute. Cable lengths and plug counts follow the ATX specification, so very large chassis may require extensions.

Checks before ordering

Verify that your case accepts a standard ATX power supply and that the total system draw stays within the 1600W rating. Confirm the motherboard and graphics cards use the native ATX 24-pin, EPS and PCIe connectors supplied with the unit. Ensure the chassis airflow path can handle the heat output when the Zero RPM fan mode disengages under load.

Questions about this item

Which capacity version of the ZXD1500 V5.6 should I pick for my build?

The ZXD1500 V5.6 is offered as a single 1600W model; choose it if your system's peak draw fits within that rating.

What does the 80 PLUS Gold rating mean for daily power use?

It guarantees at least 80% efficiency at typical loads, so less electricity turns into heat and the fan can stay off longer.

How does the ATX form factor limit where this 1600W unit can be installed?

It fits standard ATX cases, but the physical length of a 1600W unit may exceed compact chassis clearances.
