Driver Heaven posted a review on the Hiper Type M 4M630 PSU

Hiper were first known within enthusiast cycles for their Type-R PSU series released back in early 2005. We reviewed two of these units a few weeks ago and found them to be good products. That said, the Type-R units were marketed firmly at enthusiasts and could not compete against aggressively priced units in the value conscious sector. To address this Hiper introduced the Type-M series back in early 2007. We have a Hiper Type-M 630W unit for review today.
