Technical Specifications

Efficient Power for Compact Builds

The GT-300W’s 80 Plus Bronze certification ensures reduced energy consumption and lower heat output compared to standard PSUs. This efficiency translates to cooler operation and potentially lower electricity bills over time. The active PFC technology further stabilises voltage delivery, protecting your components from power fluctuations that can cause system instability or damage.

Quiet Cooling with Smart Temperature Control

A temperature-controlled 80mm fan keeps the PSU cool while maintaining minimal noise levels under 17 dBA. The honeycomb ventilation design improves airflow efficiency, allowing the fan to spin slower under light loads for quieter operation. This makes the GT-300W particularly suitable for living room PCs or office environments where noise reduction matters.

Comprehensive Protection for System Safety

Built-in protection features include Over Power Protection (OPP), Over Voltage Protection (OVP), Under Voltage Protection (UVP), and Short Circuit Protection (SCP). These safeguards work together to prevent damage from electrical faults, ensuring your valuable components remain protected during unexpected power events or hardware failures.

Essential Connectivity for Modern Compact Systems

The PSU provides all necessary connectors for typical small form factor builds, including a 20+4 pin motherboard connector, 4+4 pin CPU connector, three SATA power connectors, and one Molex 4-pin peripheral connector. This connector selection covers most compact PC configurations without unnecessary excess cables that would clutter the tight interior space.
