550W ATX Power Supply

The KHACHIMO ST-550P-AD is a 550W ATX power supply built for standard desktop builds. It delivers the rated wattage through a conventional ATX form factor. The unit suits system integrators and DIY builders assembling mid-range workstations or gaming rigs. It arrived as a new component first listed by the manufacturer in 2024.

Sustained load behaviour

The supply has been test working to confirm stable output under continuous demand rather than only peak bursts. Good quality components help maintain consistent voltage rails during extended sessions. This steady delivery protects connected hardware from ripple during long rendering or gaming workloads. The design targets reliable operation across the full rated capacity.

ATX interface limits

The ATX standard defines the physical dimensions, connector layout and signalling used by this unit. Builders must ensure their chassis accepts ATX-sized supplies and that the motherboard provides the matching main and CPU power sockets. Cable lengths follow the ATX specification, so routing in larger towers may require extensions. The 550W ceiling caps the total system draw this supply can support.

商品問答

How much heat and fan noise does the 550W unit produce when running all day?

The 550W ATX supply is tested working and built with good-quality components, which helps keep heat and noise low during continuous operation.

What must my system already have for this ATX power supply to connect and work?

Your case needs an ATX PSU mounting space and your motherboard must accept the standard ATX power connectors that this unit provides.

Will the ST-550P-AD power older components I keep in the same build?

Yes — it delivers 550W through the standard ATX interface, so it supports legacy parts that draw power from the same connectors.
