front Rosewill Tachyon 550W & Silentnight 500W Review

 

Today we have a review of the Tachyon 550W and the Silentnight 500W power supplies, two middle range, 80Plus Platinum certified products from Rosewill, the company which evolved from the in-house brand of an e-tailer to a stand-alone manufacturer. Both units share the same OEM and a similar output but each aims at a different target group. Read on to find out more about their features and performance. 

Rosewill is one of the fastest growing suppliers of PC-related products in the North America at the time of this review. The company started off as an in-house brand of Newegg, the very large and well-known electronic store, but quickly grew into a stand-alone manufacturer, exporting their products in several other countries. Today the company designs, manufactures and exports myriads of products, including hardware for advanced users and enthusiasts. In this review we will be looking at two of their middle capacity but high performance power supply units, the Silentnight 500W and the Tachyon 550W. Although both power supplies are based on the same design, each is aiming towards a different market group. Read on to find out more about their similarities and differences, as well as their advantages and disadvantages.
