Zalman ZM850-HP review at techPowerUp!
This go around, it looks like Zalman is using an Enhance 850W for their new ZM850-HP 850W semi-modular PSU reviewed over at techPowerUp!
This same Enhance platform is used by SilverStone, Antec, Cooler Master...
According to the results, the unit didn't test as well in efficiency as it's SilverStone branded cousin, but is much quieter than anything else techPowerUp! has reviewed.
