The Inter-Tech TFX-350W is a compact 350W power supply unit designed for desktop systems that require reliable, space-saving power delivery. It includes multiple connection options and a PCIe 6+2 pin connector to support discrete graphics cards with higher power needs. With an efficiency above 82% and 80 PLUS certification, the unit balances performance and energy efficiency in a small grey TFX form factor.

Advantages

The TFX-350W offers a compact TFX design (85 x 175 x 65 mm) suitable for small or slim desktop enclosures, an 80 PLUS certification for improved energy efficiency, and a dedicated PCIe 6+2 pin plug for higher-power graphics cards. It provides a 20+4 pin ATX motherboard connector and active cooling via an 80 mm fan to maintain stable operation under typical loads. The unit’s compatibility with 110–240 V AC and 50–60 Hz makes it suitable for a wide range of regions.

Suitable for

• Small form factor or slim desktop PCs with TFX power supply bays
• Office and home systems with modest power requirements
• Builds that need a single graphics card with moderate power draw using the PCIe 6+2 pin connector
