Load Regulation
It measures the stability of the output voltage when the load connected to the power supply varies.

Load regulation is tight on all rails except 5VSB, where it was extra loose.

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.

Leakage current graph is for the 1000W models so wrong graph used here, too bad your graphs don’t include Pure Power 13 M , that model seems to be a better value and maybe better unit than this.
BQ can snatch loyal Seasonic and Corsair users with these 2025 models, good job from them. Thanks for the review!
Do you think that the Dark Power 14 worth the premium over the Pure Power 13 M?
…in addition, Pure Power has more compact dimensions 160 vs 175 (Dark Power) and fits into e.g. Lancool 207, or Sugo 14, while Dark Power does not 😉
