High-Capacity ATX Power Supply

The KHACHIMO 2500W ATX unit delivers substantial power for demanding workstations and servers. It targets builders who need reliable, high-wattage output for multi-GPU arrays or dense compute clusters. Buyers seeking a modest desktop PSU should look elsewhere.

Sustained-Load Behaviour

Resonant LLC topology with DC-to-DC conversion maintains clean, consistent power during prolonged heavy workloads. The 80 PLUS Gold certification ensures high efficiency, reducing waste heat and keeping internal temperatures lower over time.

Pre-Installation Checks

Verify that your chassis can accommodate an ATX form-factor supply of this rating and that your AC circuit can handle the draw. Confirm the motherboard and GPU cable requirements match the unit's connector complement before ordering.

Questions about this item

How loud does the 2500W unit get when it runs all day?

The 80 PLUS Gold certified design keeps waste heat low, and the Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation.

What cables or connectors must I already have to install this supply?

It uses a standard ATX form factor, so your case must accept ATX power supplies and your motherboard needs the usual ATX power connectors.

Will this PSU work reliably with older components I plan to keep?

The resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine, making it compatible with legacy hardware.
