Load regulation doesn’t look good in the graphs above, mainly because of the tough competition. I am satisfied with a 1% deviation, which is the case at 5V. Still, the PSU scores in the last place in this graph, and not only.

Ripple suppression is decent.

Hi!
I’m really interested in the DP13, but I’ve read a lot of reddit threads and horror stories about it either coming with an unbearable rattling noise off the bat or with the DP13 straight up dying right after installation or some time after, a week to a year.
Have you by any chance heard anything of the current stability and safety of DP13? The reddit threads have certainly died down in the past half a year, suggesting that perhaps bequiet fixed their batches, but I’m still very nervous about it, as it’s quite a pricey faustian bargain to take.
My sample worked as I described in the review. Unfortunately, I cannot do torture testing in all PSUs I get, but what I know is that be quiet! has a very strict policy on quality, and its PSU team takes seriously everything that users report, so I doubt any problems still exist.
