Load regulation is within tight enough at 12V and 5V, but loose at 3.3V.

A glance at the light-load table is always useful, as the PSU typically operates at light loads.
Ripple Suppression
Ripple in power supplies refers to the small, unwanted AC voltage fluctuations superimposed on the DC output. It occurs due to imperfect filtering during the AC-to-DC conversion. Lower ripple is highly preferable because it ensures a cleaner, more stable DC output, reducing noise and potential interference in sensitive electronics, improving performance, and extending component lifespan. High ripple can cause instability, overheating, or damage to connected devices.

Ripple suppression is good overall.

Will you have a written reviews on the recently released Dark Power 14 models? Thank you for your work on PSUs by the way and sorry for posting it here
I will start them now that I finished the PT series.
Cybenetics reports are up. 🙂
