be quiet! TFX Power 2 300W Gold review

be quiet! are using an 80mm Protechnic Electric fan – model number MGA8012LR-A20 rated at 12V 0.15A. This fan measures 80mm x 80mm x 20mm and is classed as a server ‘square fan'. It is a sleeve bearing fan.



The design is clean inside and due to the efficiency be quiet! have only installed a single heatsink to help with cooling directly under the small fan. Soldering on the PCB seems fine.


be quiet! are using a Chinese TEAPO 85c rated capacitor in the primary stage. This is rated 420V and 180uF. TEAPO wouldn't be our first choice, but it looks as if be quiet! are working to a very specific budget. Secondary stage capacitors are a mixture of Chinese brands … mainly TEAPO.

The cables are not sleeved into the chassis, but be quiet! are using a plastic ring around the bare cables to offer protection against the raw metal.
