BTX motherboards use a 24-pin power connector.
A P1 connector is a power connector found on ATX power supplies. It is used to provide main power to the motherboard, and to control ACPI functionality (tell the power suppy to turn off and back on).
It is the control circuitry that includes all the connectors head including the supporting boards also. To identify this i.e. to name it as main board the steeper motor and carriage motor power connection is attached to this board. The main board includes the controller IC/CPU that controls the data buffering. the supporting ICs may transform the data in bit stream to generate the electrical pulses. Only in main board the Adapter power connector is attached which is markedly difference from any dependent board.
The most common power supply connectors for motherboards will be either a 20 or 24 pin connector. Older unit used less pins like the ATX but the cure standard is the 20 or 24 pin main connector.
If it as a 20 or 24 pin connector and a 4 pin connector then it is a ATX power supply.
It works like a computer. You have a main board with intergated graphics and network card. When the power cable to connected and the xbox turns on. The board will start up and boot other devices like hard drive, disk drive etc.
Connecting a floppy Drive in a Desktop ComputerYou should connect the 4-Pin 12 Volt non-molex Connector from the power supply to the power input of the Floppy Disk Drive, also the IDE ribbon cable from the FDD output on the Main-board to the FDD input on the Floppy Disk Drive, with the pink stripe on the outside of the FDD Input & Output sockets, it is important to make sure you are grounded to the case whilst doing this with the PC Power Cord plugged in but switched off

It could be due to a fault on the power supply board (Bad Caps). Assuming the 'main board' refers to the main processor board.It could be due to the new board not being an exact replacement.There could be a short circuit on the main board, taking one of the supply lines down.The plug in cables may not be seated properly or in the wrong socket.

Any SATA drive will work, that board even has an IDE input so older drives that require a ribbon cable will also still work. But there`s no sense in that, so get a good Western Digital or Seagate SATA II drive and you`re good too go. Motherboards do not care what Brand of drive you install, only how the drive connects to the board, which nowadays the main connector type is the SATA port. The drive will be automatically recognized and initialized once it`s installed, then you just partition (if you wish) and format it.
A regular ATX motherboard uses a single 20-pin P1 connector with optional 4-pin auxillary power connector
