What this power supply delivers

The KHACHIMO Z620 is an 800 W ATX unit built for modern desktop systems that demand stable output and high efficiency. It suits builders assembling new workstations or upgrading existing rigs where reliable power is a priority.

The efficiency standard that matters

Certified to 80 PLUS Gold, this supply meets strict efficiency targets across typical load ranges, reducing waste heat and lowering electricity draw during everyday operation.

How it runs quiet and cool

A Zero RPM fan mode stops the fan completely at low and medium loads for near-silent performance. Resonant LLC topology with DC-to-DC conversion keeps output clean, cuts coil whine, and supports energy-efficient sleep states for cooler temperatures.

Questions about this item

What does the 800 W rating mean for my actual system build?

The 800 W rating is the maximum continuous power the unit can deliver across all rails, so a build drawing up to that load under full stress stays within spec.

What does the ATX form factor determine for installation?

ATX defines the physical dimensions and mounting hole pattern, so the unit fits standard ATX cases and aligns with the motherboard's 24-pin and CPU power connectors.

How much clearance do I need inside the case for this power supply?

The unit follows the standard ATX depth, so any case that accepts a regular ATX power supply provides enough room for installation and cable routing.
