Default Alternatives for Seasonic PRIME?

Interesting consumer power supplies with MTBF ≥ 150,000 + Hold-Up Time ≥ 30ms + high-capacity capacitors (Titanium serie). Did not find other vendors of such power supplies. But can such PSU be available?

30 ms is double the Intel spec, so get a good supply and run it at half its rated power; this will also significantly extend its MTBF

I once took a hard drive and formatted it to less than full capacity, so only the outer part of the disks were being used; this meant it had faster average transfer rate and the heads had less far to move.

But this does not compensate for built-in high-capacity input capacitors in Prime Titanium. Russian operating conditions require high capacity capacitors.
Adding external compensation devices can degrade total reliability of computer's power system.

Robert Pease in Troubleshooting Analogue Circuits (P77) quotes MIL-217 that concludes that "a circuit's reliability decreases when components are added"; but he objects on the grounds that some of those added components are for protection.


Concerning the Titanium
https://seasonic.com/prime-ultra-titanium#specification

MTBF 150,000 hours (at 25C excluding fan)

BUT

Life Expectancy 50,000 hours (at 40C)

which fits Arrhenius' equation if the life is halved for every 10C


The tendency these days is to go for hot server rooms, given how much cooling costs.

Back to that Bulk overkill Inputs...and quite a few units now hitting the market, that you do kinda want to see the innards...some look like a decent deal and priced well.

I read about this fan. Weak link. Small rotational speeds will save service life. Electrical part has a low heat dissipation
