We didn't know what to expect when we received this latest HM Series 650W power supply from ADATA. They aren't a company we would normally associate with producing a high quality power supply.

Initial impressions out of the box were positive, the subdued appearance ensures the supply will fit well inside a good cross section of systems. Anti scratch paintwork helps to maintain the good looks over many rebuilds. The modular cabling is very well presented, with colour coded ports, all clearly labeled underneath, and a high quality felt pouch for storing the unused cables. A non modular design causes substantially more cable routing work for the end user, especially if the system is exposed with a side window panel.

Technically, there really is little to fault with the ADATA HM Series 650W power supply. Load regulation shows a healthy Channel Well design and it managed to cope with our Cross Loading stress tests. Efficiency results confirm strong 80 Plus Bronze certification and the ripple results are positive, and well within the rated parameters.

The choice of high quality Yate Loon D14BH-12 fan ensures that the components are well cooled, even in less than ideal conditions. It isn't the quietest supply we have tested, but it won't be intrusive under normal operating conditions.

Pros:

• good efficency for 80 Plus Bronze
• great paintwork
• attractive, understated design
• internal components are high quality
• modular cabling
• we like the storage pouch

cons:

• not the quietest under high sustained load

KitGuru says: An excellent all round modular power supply at a very modest price. Only £75 in the UK.
