Load regulation is within 1% on all major rails. 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 12.003V. At 40W load, the 12V rail climbs to 12.107V. If I took the 40W load test as a reference, the load regulation at 12V would be 0.23%, which is pretty tight.

Ripple suppression is good enough.

Any news about the 750w protection features?
I think you were right and a lot of people who read your review are wondering if the retail 750w model should be considered when making a purchase.
Thanks a lot for all the amazing work.
Would you consider testing the Super Flower Zillion FG ATX3.1/PCIe 5.0 power supplies? I’ve recently stumbled across them as they are currently on sale and was wondering if they were good.
Aris you should review the SuperFlower Leadex III ATX3.0
