A power supply's motherboard lead splits so it can plug into either a 20-pin or a 24-pin motherboard connector. Which lead is that?
Select an answer to reveal the explanation.
Short Explanation
The big lead to the motherboard comes apart so it can dress for an older board or a newer one. You want the 20+4 pin connector. A drive power plug, a graphics-card plug, and a legacy peripheral plug are other leads.
Full Explanation
The 20+4 pin connector is the motherboard power lead that can be used as 20 pins or as 24 pins by seating or leaving off the extra four. A supply that splits to fit either board is using that lead. A SATA power connector feeds drives. It is not the motherboard socket. A PCI Express graphics power connector feeds a graphics card. It does not replace the motherboard lead. A Molex connector is the older four-pin peripheral plug. It is not a 20-pin or 24-pin motherboard connector. Exam caveat: seat the extra four pins when the board has the 24-pin socket. Leaving them hanging on a 24-pin board can leave the board short of the power pins it expects. Operational check: match the plug to the board's socket, latch it fully, and confirm the board powers on. Seat the extra four pins when the board has a 24-pin socket. Latch the connector and confirm the board powers on. Do not leave the four-pin section hanging on a 24-pin board.
