Corsair TX vs. OCZ ZT 550W
In this review we will compare two almost identical products from OCZ and Corsair. Even so, there are still some differences between the offerings. With 550W both PSUs deliver more than enough power for most current systems. On the following pages we'll find out which handle overload situations the best, who has the highest efficiency, and which PSU provides the best voltage regulation.
With sales of more than 100,000 PSUs each month, Corsair is one of the most important vendors for retail power supplies. They have a lot of experience even if they don't own a factory. In addition they are a leading manufacturer of SSDs and (good-looking) ATX cases. A few months ago Corsair presented the latest addition to their Enthusiast series. The TX brand has the goal of delivering low prices, quality, and high efficiency. Today we take a look at the TX550M 550W and find out if they meet the requirements. It's another solution with 80Plus Bronze, one +12V output and modular cables—quite common features.

Corsair TX550M vs. OCZ ZT550W 550W

The second unit we test today is a power supply from OCZ Technology Group. They're now famous for their SSDs, but they have many power supplies as well. We'll look at the OCZ ZT-Series ZT550W. OCZ is using an 80Plus Bronze design from Great Wall with a few changes in the details. The 80 Plus Bronze certification is standard for any decent PSU today, but maybe it's good enough to beat up Corsair. An advantage is the fully modular design, which is an uncommon feature for the mid-range price segment (except SilverStone's Strider Plus 500W).
