Cooler Master's Real Power Pro 850W is targeted at the enthusiast who craves the latest (and often most power-hungry) technology and requires a PSU that's up to the job.
The 3.5kg box is testament to the heavy-duty PSU inside. Classic Engrish [sic] is in evidence from the Taiwanese manufacturer. Always good for a laugh.
The contents include the PSU itself (duh!), 3-pin power cable, a pack of screws, and a multi-language booklet that provides basic reference material, much of which is quoted in the table above.
The rear has a honeycomb pattern that's designed to increase the airflow within the unit, with the fan pushing air through the PSU. Note that there's no PSU power switch, so hard resets will require manually unplugging the mains cable or switching off at the mains.
Taking into account the larger-than-normal fan used and the PSU's dimensions, you'll need a wide chassis to accommodate it comfortably.
