GameMax GT300 300W TFX Power Supply - Compact Efficiency for Small Form Factor Builds

The GameMax GT300 delivers reliable 300W power in a TFX form factor designed specifically for small form factor and compact desktop systems. This 80 PLUS Bronze certified power supply achieves up to 85% efficiency, reducing energy waste and heat generation while maintaining stable power delivery for your components.

80 PLUS Bronze Certified Performance

Certified for 80 PLUS Bronze efficiency with active PFC (Power Factor Correction) reaching up to 0.99, the GT300 ensures optimal power conversion and reduced electricity costs. The unit operates at maximum 85% efficiency across typical load ranges, making it suitable for budget-conscious system builders who need reliable performance without compromising quality.

Optimized for Compact Chassis

The TFX form factor measures just 85 x 65 x 175 mm, fitting seamlessly into slim desktop cases and HTPC builds. Three L-shaped SATA connectors simplify cable management in tight spaces, while the 4+4 pin CPU connector supports modern processors. The compact 0.9 kg unit includes a 20+4 pin main connector, one 4-pin Molex, and all essential connectors for small form factor configurations.

Quiet Operation with Intelligent Cooling

An 8cm fan with intelligent speed control keeps noise levels below 17 dBA while maintaining proper cooling. The honeycomb ventilation design promotes optimal heat dissipation through the high-end SECC 0.6mm casing, ensuring components stay cool even under sustained loads. The fan automatically adjusts speed based on temperature, balancing acoustic performance with thermal management.

Comprehensive Electrical Protection

Multiple protection circuits safeguard your system components: OPP (Over Power Protection), OVP (Over Voltage Protection), UVP (Under Voltage Protection), and SCP (Short Circuit Protection). These safety features prevent damage from power anomalies, backed by CE, FCC, and CB safety certifications. The unit is rated for 100,000 hours MTBF and includes a 2-year warranty.

ATX 12V 2.3 Compatibility

Full compatibility with ATX 12V 2.3 standard ensures the GT300 works with current motherboards and components. The 100-240 VAC input accepts worldwide voltage standards, though a power lead is not included with the unit. Package includes mounting screws, two cable ties, one Velcro strap, and installation manual.
