In the photo of the new power supply 4 pin connectors, the connector on the left is a universal fit configuration. It will fit in any 4 pin connection on an atx motherboard. I know Corsair uses it. The connector on the right is not a universal fit; however, it will fit one side of an 8 pin connection on a motherboard. You just have to look at the shape of each individual pin (round vs square) and match it up to the left or right side of an 8 pin connection on your motherboard.
