The be quiet! Dark Power 13 850W uses a high-end FSP platform which offers top efficiency, dead silent operation and ATX v3.0 and PCIe 5.0 compatibility. If only performance was higher.
be quiet! strengthens its cooperation with FSP with the Dark Power 13 series. Because of the Titanium efficiency, the platform uses a bridgeless APFC design for lower power losses. Moreover, the quiet operation was among the top priorities, with the unit achieving below 15 dBA average noise, scoring an impressive Cybenetics ETA-A++ rating. This brand is known for its silent operating products, and the Dark Power 13 line is a fine example. You cannot go wrong with a be quiet! PSU, if you mostly care about noise output.
The Dark Power 13 uses a fluid dynamic bearing fan driven by a highly relaxed fan speed profile. I agree with the non-inclusion of a semi-passive mode. There is no need for a fan-stop option from the moment the fan’s noise is negligible at low speeds, and the bonus is that there is no heat build-up at the PSU’s internals.
