500W to 550W: 12 Power Supplies Compared

Sunbeam Tuniq Potency POT550 - Overview

Sunbeam is a company based in Taiwan, selling products in both the US and European markets. They became famous for their modding products several years ago, and those continue to sell quite well. They now manufacture cases, coolers, and power supplies -- many of our readers should be quite familiar with their well-regarded Tuniq Tower 120 CPU cooler. The Tuniq Potency is black like most of the other power supplies, with a 120mm fan and two 25A 12V rails.

The internals look very similar to the OCZ ModXStream Pro; in fact, it's exactly the same layout with the same Transcend Electrolytic capacitors. There are small press/copper plates between the components and the heatsinks in the middle, though we aren't sure how necessary/effective these are as they're too small to be all that useful. The primary difference between the OCZ ModXStream and the Sunbeam Tuniq Potency is the cable management system on the OCZ unit.
