| Dec 12, 2019 at 0:54 | comment | added | Russell McMahon♦ | Lifetime (if properly calculated) is an MTBF (mean time between failures) figure based on an overall calculation of failure rates of all components. | A and perhaps THE major failure mode is electrolytic capacitor degradation. ECap lifetimes about double per 10 degrees drop in their mean operating temperature - so keeping a supply cool and/or blowing more cool air over the Ecaps and/or lightly loading it on average are all probably useful factors. If there are other heavily loaded components they too will usually benefit from additional cooling. | |

| Dec 11, 2019 at 20:55 | comment | added | Stelios Liakopoulos | @EugeneSh. but what causes it to fail? What components usually break down? | |
| Dec 11, 2019 at 20:53 | comment | added | Eugene Sh. | OK, I see it "long lifetime upto 5-8 years". So it is how long it is typically working with a typical usage | |

| Dec 11, 2019 at 20:47 | comment | added | Eugene Sh. | Where does it say it can last 5-8 years? | |
