Be Quiet! Straight Power 11 650W died (end 2019 - 11.05.2026 2:33am)
It fired a 7700k with a 560Ti till 2022 and then a 1070Ti. Other components are: 4 Fans (12cm), 4x8GB DDR3 (i think) + 1 m.2 + 1 hdd over the whole time. The usage was light (mainly office, seldom more "heavy" use aka browser or opening windows media player, twice ultra heavy load aka installing windows/drivers/programs and once running benchmark for an hour to test system stability).
It died at night while PC off with a barely audible crk fzz. Overvoltage/Undervoltage/Overcurrent is out of the question, it ran in a stabilized environment. It just decided to go off while be(ing) quiet. I did not open it to check what is going on.
The warranty from be quiet for this was 5 years. The system ran stable all the time. Their promise was thus fullfilled 🫡 (aka we dont expect failure in warranty time).
To be fair: we were at least 100W away from Pmax. It ran at like 50-120W most of the time. It didn't die with a bang while running which is good. In the view of all that I'd have loved to see it going for at least 8-10 years. As comparison:I bought imo an Ultraforce 650W in 2011 which powered a 2600k then 4790k then 5950x with said 560ti, then said 1070ti, then a 2060S in a way heavier system. It got unstable, but by then it was over 14 years old (and that thing got the heavy duty treatment - like 8hrs per day+ gaming). It died end of last year.
So... My verdict: the straight line is the lower end of their lines. Price wise it was okish initial (imo 65€ in 2019), but in the view of how long it kept going rather not so good (the ultraforce was a bit higher in price at its time, but by far not 50 or 100% above). It kept the system safe even after death. So overall: it did the job well, but longevity left much open.
I'm still deciding what to do. On one hand: the system components are all quite old and efficiency is not that good anymore. I want to upgrade my girls PC. Maybe when the new AMD 10k come a 10800x3d + 9070xt - something along these lines. So I can go with another Seasonic Prime 1600 Noctua edition and just call it a day (or better 15 years) or go with a much more well dimensioned (yet more inefficient) 1000W Pure Power, but maybe have to swap it out in another 5-7 years?
