## Long description

Aqirys AQRYS\_PULSARLS550W is a 550 W ATX power supply designed for desktop PCs and standard ATX builds. It delivers up to 550 watts of continuous power and uses a 20+4 pin ATX motherboard connector. The unit is non-modular with fixed ribbon-type cables including CPU, PCIe and SATA leads, and operates on 200–240 V AC at 50–60 Hz. Efficiency is rated 80 PLUS White. Cooling is provided by a 120 mm fluid-dynamic bearing fan and the PSU comes in a compact black ATX form factor suitable for system upgrades and new builds.
Advantages
The Aqirys PULSAR LS 550W combines a reliable 550 W output with an 80 PLUS White efficiency rating to balance performance and power consumption. It incorporates a Japanese main capacitor rated for 105°C and Active Power Factor Correction for improved electrical stability. The integrated protections include over-voltage, under-voltage, over-current, over-power, over-temperature and short-circuit safeguards. Fixed black ribbon cables improve cable management and airflow within the case, while the 120 mm fluid-dynamic bearing fan offers effective cooling with controlled noise levels.
Suitable for
Home and office desktop PCs requiring a 550 W ATX power supply
Entry to mid-level gaming systems and upgrades using discrete GPU and standard storage arrays
System builders who prefer fixed ribbon cables for cleaner internal layouts
Compact ATX cases where a standard non-modular PSU fits the build

How to use
Install the Aqirys AQRYS\_PULSARLS550W into a compatible ATX case following standard safety procedures: disconnect mains power before installation, secure the PSU to the case with the supplied screws, and connect the 20+4 pin ATX cable to the motherboard. Attach CPU, PCIe and SATA connectors to the corresponding components, ensuring correct orientation and firm seating. Verify input voltage selection if present and route the fixed ribbon cables to optimise airflow. After connecting all components, power on the system and confirm stable boot and normal operation.
Usage recommendations
Use this power supply in systems where total component power draw does not exceed the rated 550 W. Maintain case airflow by arranging the fixed ribbon cables to avoid blocking intake or exhaust paths, and keep the PSU intake and fan clear of dust. For reliability, pair the PSU with a compatible motherboard and components within the recommended voltage range and consider periodic visual inspection of connectors and the fan for dust buildup.
