"In this review, we will take a closer look at the CS650M with, as its model number implies, a capacity of 650 W. Its single +12V rail can deliver up to 51 A, which can, along with the four PCIe connectors that equip the PSU, feed two mid-level VGAs for a SLI or Crossfire configuration. The CS650M's price also looks fair for what it offers, but we will put together a clear picture of its price/performance ratio once we finish all testing and have the necessary data in hand to precisely calculate the performance-per-dollar score. When it comes to commercial products like PSUs, the most interesting bit is the performance they offer in relationship to their price, and we really busted our heads to implement an algorithm that effectively calculates the pure performance of a PSU by taking into account all of our test data, but that is another story we already told here."
