Load regulation is tight enough only at 5V. The 12V rail’s load regulation could be tighter if its voltage level weren’t as low at the 20W load, which is my start point at 11.907V. At 40W load, the 12V rail climbs to 12.01V. If I took the 40W load test as a reference, the load regulation at 12V would be 0.28%, which is pretty tight.

Ripple suppression is good.

Bad fan profile settings. Initial fan speed is too high, 940 rpm is loud. It was better before.

Nope, I don’t remember testing this unit! Basically I never heard of this brand before. Hmm, I will investigate this.
i’ve seen that the Maxwell Duke 1000W internals looks like 1stplayer NGDP 1000W https://photo.coolenjoy.co.kr/data/editor/2407/647933e3d3d50b746a68c7235da86ad64c5491bb.jpg this is your tearing down the ngdp 1000w https://hwbusters.com/wp-content/uploads/2023/09/top1-2.jpg
This new series is a disappointment
