KitGuru reports this model offer good efficiency for a 80Plus Bronze power supply. The main downside is the loud fan in high load.

"Many regular readers this will never have seen an ‘ADATA’ branded power supply before, however like many companies in this sector, the underlying design is created elsewhere. The HM Series 650W power supply we are looking at today is actually based around a Channel Well Design – a company who have made power supplies for other companies in the past such as Thermaltake, Antec and Corsair."
