Does it really matter? Its not a cheap Chinese thing for sure. I used it to run a server for a while with 6HDD's I know its capable of powering the units. But maybe I am just being ignorant?
What make would you recommend and why?
Maybe, but since you said it can run 6 hdd, then we can pass the psu.
The other culprit maybe overheat. Some already open the heatsink & report that the work around the chip is a mess.
