Introduction

Cooler Master is perhaps most well known for its cases and cooling units, as its name implies, but Cooler Master also has a line of powerful power supply units. The Cooler Master Real Power Pro 650W PSU is the Taiwan-based company's newest offering in its PSU line. ThinkComputers previously reviewed Cooler Master's eXtreme Power Duo 600W PSU and it performed well receiving a 9 out of 10 score. We will see if the Real Power Pro can perform just as good if not better.

Packaging

The packaging is very minimal, yet well-designed and informational. The box bears all of the information given in the Specifications section of this review. The box also has pictures and descriptions of each connector and a number indicating how many of each the PSU has.

The box is well-protected with packing polystyrene. It includes the PSU, a power cord, some mounting screws, and a manual.

For the interested, the manual is in English, French, German, Italian, Japanese, Portugese, Spanish, Dutch, and Chinese (I think-could be Thai).
