The following are the basic connector you can see in a power supply:
 ATX 24 pin main power connector is the standard motherboard power connector
used in nearly every computer.
 SATA 15 pin power supply connector is one of several standard peripheral power
connectors. SATA power connectors only connect to SATA drives like hard drives and
optical drives. SATA power connectors do not work with older PATA devices.
 Molex 4 pin power supply connector is a standard peripheral power connector.
Molex power connectors connect to many different kinds of internal peripherals
including PATA hard drives and optical drives, some video cards, and even some other
devices.
 Floppy drive 4 pin power supply connector is the standard floppy drive power
connector. The floppy power connector, also called a Berg connector or Mini-Molex
connector, is included in even the newest power supplies even though floppy drives
are becoming obsolete.
 ATX 4 pin power supply connector is a standard motherboard power connector used
to provide +12 VDC to the processor voltage regulator. This small connector usually
attaches to the motherboard near the CPU.
 ATX 6 pin power supply connector is a motherboard power connector used to
provide +12 VDC to the processor voltage regulator but the 4-pin variety is the more
commonly used connector. This small connector usually attaches to the motherboard
near the CPU.

Motherboard
The Motherboard is also known as mainboard, system board, logic board or MOBO.
It holds and allows communication between the crucial components of the computer such as
the CPU and memory. It also provides connection for other peripherals. This provides the pat
