1800W ATX Power Supply

This KHACHIMO R750 R750XS unit delivers 1800 watts through an ATX form factor. It is built for workstations and high-end desktops that demand sustained heavy loads. The D1800E-S0 model carries 80 PLUS Gold certification for efficient power conversion.

Suitable for high-power single systems

Enthusiasts running multi-GPU arrays or compute-heavy workloads will benefit from the resonant LLC topology with DC-to-DC conversion. Builders assembling compact or budget-oriented rigs should look at lower-wattage units that match their actual power envelope.

80 PLUS Gold efficiency rating

The Gold certification confirms high efficiency across typical load ranges, reducing waste heat and electricity cost. Zero RPM fan mode stops the fan at low and medium loads for silent operation. Modern Standby support enables faster wake-from-sleep transitions.

Questions about this item

How can I confirm the 80 PLUS Gold certification is active after installing the 1800W unit?

The power supply will deliver up to 1800W with high efficiency, resulting in lower power draw, reduced noise and cooler running temperatures under load.

What cables are included with the ATX power supply and what must I source separately?

The unit ships with the standard ATX connector set required for motherboard, CPU and GPU power; any specialised adapters for legacy components would need to be purchased separately.

Which model variant should I choose between the R750 and R750XS designations?

Both designations refer to the same 1800W ATX platform with Modern Standby support, Zero RPM fan mode and resonant LLC topology with DC-to-DC conversion.
