Power Supply Unit Silverstone SST-DA750R-GMA 750 W

The Silverstone SST-DA750R-GMA 750 W power supply unit delivers stable power for ATX-based PCs with 80 PLUS Gold efficiency. It includes a 24-pin ATX motherboard connector, a silent 120 mm fan with semi-fanless operation, and flat cables for improved flexibility and tidier cable management. The unit supports a 12V-2x6 (12+4 pin) PCIe connector compliant with ATX 3.0 to handle instantaneous GPU peak power and uses a powerful single +12V rail architecture for reliable output during upgrades or overclocking.

Advantages

The PSU is designed for high efficiency (80 PLUS Gold) to reduce wasted heat and lower power consumption. Flat cables increase flexibility and ease of routing inside the case. A specially designed cover aids in dissipating residual heat. The semi-fanless 120 mm fan ensures quiet operation at low loads while providing active cooling when needed. Advanced protection features (over current, over power, over voltage, short circuit, under voltage and over temperature) enhance system safety.

Suitable for

• Gaming PCs with modern graphics cards that require ATX 3.0 / 12V-2x6 PCIe support
• Workstations and home PCs that need reliable 750 W power delivery
• Systems where cable management and compact routing are important
• Users planning future component upgrades or light overclocking

How to use

Install the Silverstone SST-DA750R-GMA into a compatible ATX case and secure it with the supplied screws. Connect the 24-pin ATX cable to the motherboard and use the 12V-2x6 PCIe connector for modern graphics cards according to the GPU manufacturer’s power requirements. Route flat cables along case channels or behind the motherboard tray for improved airflow and tidiness. Ensure AC input falls within 90–264 V and switch on the system; the semi-fanless fan will remain quiet at low loads and engage as temperature or load increases.

Recommendations

For optimal performance, place cables to avoid obstructing airflow, verify GPU power connector compatibility before installation, and ensure adequate case ventilation. Regularly check system temperatures and the PSU fan for dust build-up to maintain cooling efficiency and longevity.
