Load regulation is not tight enough.

Ripple suppression is satisfactory but not competitive.

Does your Dark Power model suffer from a fan that spins with an “rrrrrrrrrrrr” noise?
I have a Dark Power Pro 12 and some user reviews of the Dark Power 13 in the UK report that the fan noise is persistent.
There are some areas where then noise is increased, because of the bearing noise, but it is too low in general.

I got two Dark Power 13 100W from two different online retailers and they both have obvious bearing noise. Stay away.
A bit of further messing about, it seems that the one I tried it with would make no irregular fan noise when placed fan up, but makes obvious bearing noise when oriented fan down.
A review of the be quiet! Dark Power Pro 13 1300W (or 1600W) would be very welcome.
The 1600 is on my list 🙂
Great! Do you have a time frame for the release of your review?
