TFX 300W Bronze PSU for compact builds
This TFX form factor power supply delivers 300W continuous output at 40°C and carries 80 PLUS Bronze certification. It fits small chassis that require the thinner TFX profile while maintaining ATX12V v2.4 compatibility. The unit is rated for 24/7 operation in always-on systems.
Replaces proprietary slim PSUs when efficiency
The adapter upgrades older low-efficiency TFX units in office PCs or home servers where the original supply lacks active PFC or Bronze-level efficiency. The jump is worth it when the existing unit runs hot, lacks protection circuits, or cannot sustain 300W under load. It is not for builders who need higher wattage or modular cabling.
Steady 300W at 40°C with quiet 18 dBA fan
The single 80mm fan operates at a minimum of 18 dBA while maintaining full rated output at 40°C ambient temperature. Active PFC, over-power, over-voltage and short-circuit protections engage under sustained load. Dual +12V rails provide 14A and 15A respectively for stable distribution.

Questions about this item
Will the TFX form factor fit my slimline case mounting holes?
The unit follows the standard TFX form factor so it aligns with the mounting holes used by slimline cases designed for TFX power supplies.
How do I connect the PCIe 6-pin plug without bending the pins?
Route the fixed cable to the graphics card, align the keyed 6-pin connector, and press straight in until the latch clicks; forcing it at an angle is the step most people get wrong.
When should I clean the 80 mm fan to keep noise near 18 dBA?
Use compressed air to clear dust from the fan intake every six to twelve months; a clogged fan spins faster and raises the acoustic level above the rated minimum.
