Introduction is a company specializing in hard-to-find connectivity and technology parts, which it manufactures. recently sent us a WattSmart 750W EPS12V 80 PLUS Power Supply (EPSPOW750PRO) for review, and we were impressed by the quality and features present in this model: quad 12v rails, high energy efficiency, dual ball-bearing fans, and more connectors than we'd ever need.

The 80 PLUS program is a unique forum made up of electric utilities, the computer industry, and consumers. The organization's goal is to bring power-efficient power supplies to both desktops and servers. For a power supply to qualify for this certification, it must be able to achieve 80% or greater energy efficient at 20%, 50% and 100% of rated load with a true power factor of 0.9 or greater. The efficiency is calculated by dividing the power drawn from the wall (AC) by the power the power supply outputs (DC). For every 100W of AC power used, the power supply must output atleast 80W of DC power.

Packaging & Appearance

One of the things I like the most about's packaging is that it's different than most other companies you tend to run into. Instead of your typical, small cardboard box, packaged the power supply in a glossy box covered in the color scheme. A sticker on the top of the packaging shows a picture of the power supply, the name, and some of the awesome features.

The box opened up to reveal a bubble-wrapped power supply and a spare power cord. Removing the bubble wrap, I found an attractive, dark-gray-colored power supply, and several cables fully sleeved in black nylon.

The power supply itself measures 7.5 inches in length, and approximately 3.5 inches in height, while the power cables reach about 16 inches. With 16 inches of cable, there shouldn't be anything in even a full tower case that this power supply can't reach.

Also featured on the EPSPOW750PRO are two dual ball-bearing fans, engineered for longer life and quiet usage. One is located on the rear of the unit, while the other resides on the front. Unlike many current power supplies, there is no fan on the underside.

The EPSPOW750PRO isn't a modular power supply, nor is it small by any means. With the long 16 inch cables, this power supply isn't going to leave much airflow in smaller cases. However, with four 12v rails, the EPSPOW750PRO is ideal for server or advanced desktop usage. Let's take a look at the unit's features and specifications on the next page.
