Silverstone TX300 TFX Power Supply

The Silverstone TX300 is a 300W TFX12V power supply built for small form factor systems that require a compact footprint. It suits builders assembling slim desktop cases or upgrading proprietary OEM chassis where standard ATX units will not fit. The unit carries 80 PLUS Bronze certification and is rated for continuous 300W output at a 40°C operating temperature.

Sustained load performance

The power supply delivers its full 300W rating continuously at 40°C, making it suitable for 24/7 operation without derating. An 80mm fan keeps noise to a minimum of 18 dBA under typical loads, while active PFC helps maintain stable input current. Efficiency meets 80 PLUS Bronze levels, reducing waste heat during extended use.

Compatibility checklist

Verify that your case accepts the TFX form factor and that the fixed cable set provides the connectors your components need. The unit includes a single PCI-E 6pin connector for graphics power, so confirm your GPU does not require additional or different power inputs. Ensure the 12V rail capacity matches the demands of your CPU and graphics card before ordering.

商品問答

How loud is the 80 mm fan when the TX300 runs continuously at full load?

The 80 mm fan is rated at 18 dBA minimum, so even during 24/7 operation at 300 W and 40 °C the noise stays very low.

Which power connectors must my motherboard and graphics card already provide for this TFX unit to work?

The TX300 has fixed cables with a 24-pin ATX connector, a 4+4-pin CPU connector and a single PCI-E 6-pin connector; your board needs matching sockets.

Will the TX300 fit and power a legacy TFX chassis that only has a 12 V rail?

Yes, the TX300 is a standard TFX12V design with Active PFC and 300 W continuous output at 40 °C, so it drops into older TFX cases and delivers the 12 V power they expect.
