Silentmaxx Fanless 423W PSU
| Fanless 423W PSU [Discontinued] | £110.00 |
And now for something completely different! For many years, customers have been asking for power supplies which are completely silent - with no fan whatsoever. Of course this is an extremely difficult challenge from a technical/cooling point of view. But now we are privileged to bring to market a range of power supplies that noise-wise, really are "as good as it gets"! Introducing the Silentmaxx Fanless 423W.

This power supply has been developed and built in Germany using all of Silentmaxx's expertise in chassis design and electronics. The chassis has been developed from scratch with noise elimination as the primary design goal. We are delighted to say that this is achieved with flying colours!
Fanless 423W
The Fanless 423W power supply (pictured above) is 100% fanless. This obviously means it does not make any noise whatsoever! The heat generated by the power supply is transferred to a large heatsink mounted at the rear of the unit using a special patented heat transfer system (Silentmaxx guard the exact details of this very closely!). So if you are looking for the highest quality fanless power supply on the market it does not get better than this.
Installation considerations
Fanless power supplies can become very warm. With this in mind, we recommend that you maintain good airflow through your PC system and make sure there is plenty of open space around the back of the machine.
