Xigmatek NRP-PC702 700W PSU - Introduction


Xigmatek may be a relatively new player in the market but their innovative cooling solutions and various power supply units quickly earned the company a good reputation. We have reviewed many of their cooling solutions and high performance power supply units in the past few months and today we are going to have a look at a new PSU from their NRP-PC range, the NRP-PC702 700W. Xigmatek aim the NRP-PC range at the mainstream market, combining value and good performance for the average users who want more than just a cheap product for their systems. Xigmatek makes some bold claims about the performance and electrical efficiency of their NRP-PC702; let’s see if they have achieved their goals...

Manufacturer Features & Specifications
