Introduction
We reviewed no less than three high output power supply products from Xigmatek in the past few months all of which were premium products and received glowing reports. Today we will test the performance of a mid-range product from Xigmatek, the NRP-MC651 650W. The NRP-MC651 is sourced from the same range as the MC851 850W which we reviewed not long ago. The unit on test today however is considerably less expensive and meant to compete in the mainstream market. Today we will find out the corners Xigmatek have cut to reduce the price for the different market.
