The PSU cables aren't labeled, which is a bit confusing.
Bought the BeQuiet SFX-L Power 500. Cables are not marked and I am somewhat perturbed. There is a standard 20+4 pin cable for the Mainboard, but the other side splits into a 20 Pin and an 8 Pin connector. For the CPU I can only imagine I am supposed to use this 10 pin P8 connector? (Middle two pins have no wiring on that cable). So 28 Pins on PSU side for Mainboard, 20+4 on MB side 10 Pins on PSU side for the CPU, 8 on MB side. Is this right? (In the image basically the two MB connectors for the MB cable, the P8 connector for the CPU)
Examine the label... two lines of text, the top row for the connector rows. Correct. The connectors should be labeled properly. You shouldn't be able to place them in incorrect headers on the power supply (unless you really try).
I understood the question, but I wasn’t sure about the P8 connector or its pin configuration. It uses ten pins and has two unconnected ones—thank you for asking!
They likely employed a 2x5 connector to avoid reusing the 2x4 header, maintaining a similar appearance to the MB header, which might lead users to connect the wrong connector. Alternatively, earlier models could include additional wires for Sense, allowing direct voltage measurement at the motherboard entry point to fine-tune voltage based on losses in the power supply connections.
