I just got a new power supply and the 24 pin ATX connector is actually a 20+4 connector. The first 20 pins are on one connector connect just fine into the MOBO. However, the last 4 are on another connector that (due to the shape of the connector) I am unable to plug in both the 20 and 4 pin connectors into the MOBO. I just have the 20 pin connector seated, and the 4 pin connector dangling. Is this ok? What's the deal with 20+4 configuration?
