Super Flower SF-1300F14XG (WH) 1300W power supply

Leadex VII Gold 1300W ATX 3.1

This 1300W power supply targets high-end desktop builds that need reliable delivery for multi-GPU configurations or intensive compute workloads. It carries 80 PLUS Gold and Cybenetics Platinum certifications and meets the Intel ATX 3.1 and PCIe 5.1 specifications. A fully modular cable set with ribbon-style wires keeps routing clean in white-themed cases. The unit operates on 100V to 240V input with active PFC.

Sustained-load behaviour

At 20 percent load the PSU delivers 87 percent efficiency, rising to 90 percent at 50 percent load and holding 87 percent at full rated output. Cybenetics testing shows 89 percent overall efficiency at 115V input and 91 percent at 230V input. The single +12V rail design maintains stable voltage during prolonged heavy draws without the current balancing issues of multi-rail layouts. Modern Standby support allows low-power sleep states without rail instability.

Thermals noise and power draw

A 140mm fluid dynamic bearing fan runs under the Cybenetics Standard+ noise rating, keeping acoustic output low during typical gaming or workstation sessions. All internal capacitors are rated 105°C Japanese components, supporting long-term reliability at elevated internal temperatures. The compact 150mm depth leaves room for airflow in most ATX chassis. Protection circuits include over-voltage safeguards for connected hardware.
