Inside, the unit comes with all the cabling necessary to install into your box.  The chassis itself is brushed aluminum, with good machining and no obvious quality control issues.  The size is standard for 500W-class units (which is about one inch longer than the traditional 350W units that dominated in the early days.  Something to think about if you have an existing top-mounted blowhole in your case).

   One feature that sets this unit apart from the norm are the modular connection points in the rear of the unit, where you connect the included proprietary cables. I won't editorialize on this point any further than to say that modular connections should be standard on every unit, except perhaps in uber-mission-critical applications where the miniscule voltage drop from an extra connection point is unacceptable.  Fortunately, few of us use computer power supplies to operate heart-lung machines. 

   As with most power supplies, the voltage outputs are labeled on the body of the unit itself.  I'll talk a bit about the electrical qualities later in the article. 

   Another feature the Sintek sports is the ability to control the memory and PCI-E voltage rails from the back of the unit (+/- 5%).  This is a feature only the hardcore overclocker would actually use, although mainstream users may wish to fine-tune the outputs to match the ideals that their hardware recommends.

   Finally, provision is included to vary the fan speed to alleviate noise concerns.  Ideally, this would be handled automatically based on temperature, but manual control is better than no control.
