XFX introduced the Pro Series Core Edition power supply lineup, this is a new series of non-modular PSUs with a single +12V rail. They are available in 650W, 750W and 850W editions.
These are non-modular, single 12V rail design PSUs which feature what XFX refers to as "EasyRail" technology, that ensures all components get to draw their required amount of power since a single-rail design is more accommodating compared to a multi-rail design. It is available in 650W, 750W, and 850W models. The company did not detail the connector layout of each model in detail, but we can tell that all models are SLI and CrossFire certified, and going from bottom up, support 2-way and 3-way multi-GPU configurations.
