Load regulation is within 1% on all rails, unlike the Dark Power 13, especially at 230V, where the 12V rail initially started high at light loads and suddenly dropped at 20% load (from 12.185V @ 10% load to 12.032V @ 20% load).

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.
Aris, when you ill add the certification of husky 1200w on database?!
