KHACHIMO 500W ATX Power Supply

The KHACHIMO 500W ATX power supply delivers 500 watts of continuous power for mainstream desktop builds. It targets system integrators and upgraders who need reliable energy delivery for standard components. The unit carries 80 PLUS Gold certification and supports Modern Standby for rapid wake times. Its compact ATX form factor fits typical chassis layouts.

80 PLUS Gold efficiency and headroom

Gold-rated efficiency reduces waste heat and keeps fan speeds lower across typical workloads. The 500W capacity handles mid-range graphics cards and multi-core processors with comfortable overhead. Peak demands from heavy gaming or sustained compute tasks will approach the unit’s limit. Builders planning dual-GPU arrays or extreme overclocking need a higher-wattage model.

Modern Standby and ATX constraints

Modern Standby compatibility enables ultra-fast sleep transitions on supported motherboards and operating systems. The ATX specification fixes physical dimensions and connector placement, limiting cable routing options in compact cases. DC-to-DC conversion improves voltage regulation but does not alter the standard 24-pin and peripheral connectors. Systems requiring server-grade redundancy or non-ATX form factors cannot use this unit.

Questions about this item

Will this ATX power supply work with my older motherboard that still uses a 24-pin connector?

Yes, the ATX form factor uses the standard 24-pin main connector that has been common on motherboards for many years.

How can I verify the 80 PLUS Gold efficiency is active after installation?

The unit will run cooler and the fan will stay off longer under light loads because Gold-rated efficiency reduces waste heat at typical desktop power levels.

Does the box include all power cables or do I need to buy extra PCIe connectors for my graphics card?

The package contains the power supply unit with its fixed cable set; check the connector ends against your components to see if any adapters are required.
