ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a motherboard of a desktop, and more specifically, to a motherboard with a 4-pin ATX power male connector.
BACKGROUND OF THE INVENTION
With the advance of electronic science and technology, the multimedia computers have high audio and video quality. And the increasing use of personal computers also has driven the development of computer industry to become more vigorous. For instance, PENTIUM 4, the fourth generation CPU manufactured by Intel, has a more fine and complicated internal frame fabricated with the process of 0.13 micrometer to provide powerful computing functions. However, with the structures of the CPU becoming more enormous and complicated, and the power consumption thereof has increased substantially. And it is a challenge to apply the prior power supply configured to provide sufficient power for driving the PENTIUM 4®.
Please refer to
FIG. 1A
, where the motherboard applied to support the PENTIUM 4 CPU is illustrated. The components configured on the motherboard comprise a socket
12
to mount the PENTIUM 4® CPU from Intel Corp. and a chipset
14
constituted with a memory controller hub (MCH). Besides, four sets of RIMM sockets
16
located on the motherboard are applied to mount memory devices, and an accelerated graphics port (AGP)
18
is designed to mount a graphic card. And five sets of PCI ports
20
are applied to install expansion cards.
It is noted that according to the motherboard specification prior to the PENTIUM 4 CPU, only the ATX power supply male connector
22
with twenty pins is configured on the motherboard
10
to provide the power for driving various components thereon as shown in FIG.
1
B. And only one pin (Pin
1
) of the ATX power male connector
22
is applied to provide 12 volts of DC voltage for the CPU operation, as shown in FIG.
1
B. The other pins thereof are applied to provide +5 or +3.3 volts DC power or ground for driving the chips and devices on the motherboard
10
.
However, abundant power is required to provide the CPU operating in a stable state because the PENTIUM 4 CPU has an normous core frame and higher execution rate. For the purpose of preventing the computers from crashing frequently due to lack of power supply, a square male connector
24
is provided by Intel in the specification of motherboard for providing the PENTIUM 4 CPU an extra +12 volts power supply. As illustrated in
FIG. 1B
, the square connector
24
has four pins arranged in a square. Two pins (+12V DC) of the square connector
24
are applied to provide +12 volts of DC power and the other two pins (GND) are applied to connect to ground.
Because of applying the above four pins to provide an extra +12 volts for the PENTIUM 4 CPU, it is required to add a new connector of power supply suitable to the specification of the PENTIUM 4. Please refer to
FIG. 2
, in which the power supply
30
supporting the motherboard of the PENTIUM 4 is illustrated. The power supply
30
has four types of power lines. An ATX female connector
32
with twenty pins can connect with the 20-pins (20-pins) ATX male connector
22
to provide power for the CPU and the chips on the motherboard
10
. And a large 4-pins female connector
34
, called a 5.25 inches (5.25 inch) drive connector (P7), is applied to connect and drive peripheral devices such as hard disks and CD-ROM drives. As to a small 4-pins female connector
36
, called a 3.5 inch drive connector (P9), is applied to connect and drive the soft diskettes. Besides, a square female connector
38
with four pins is applied to connect with the square male connector
24
on the motherboard
10
to provide power for CPU operation.
However, for the present desktops, the ATX power supply only includes the above 20-pins ATX female connector, the 5.25 inches drive female connector and the 3.5 inches drive female connector. Namely, there is no extra square female connector suitable to the motherboard of the PENTIUM 4. Thus, when consumers want to upgrade their present desktops with a PENTIUM 4 motherboard and CPU, they have to pay much money to buy the new ATX power supply
30
with the extra square female connector
24
for supporting the specification of the PENTIUM 4.
Therefore, how to provide sufficient power for the operation of the PENTIUM 4 CPU based on the present ATX power supplies and housings is an important issue. And for the consumer, they can still use their prior ATX power supply to provide an extra +12 volts of DC power for supporting the PENTIUM 4 motherboard and ensuring the reliability and stability of operations thereof.
SUMMARY OF THE INVENTION
One purpose of the present invention is to provide a motherboard that can support processors such as the PENTIUM 4 and above for satisfying the prior ATX power supply.
Another purpose of the present invention is to provide a motherboard with multiple power supply connectors, whereby the prior ATX power supply can be applied to provide the PENTIUM 4 CPU enough power.
The present invention provides a motherboard with a multiple power supply. The components formed on the motherboard comprise a 20-pins ATX power male connector and a 4-pins ATX power male connector. The 20-pins ATX power male connector is coupled electrically with devices and a CPU socket on the motherboard through circuits thereon. And the 4-pins ATX power male connector with four pins configured in line is applied to provide individually +12 volts/ground/ground/+5 volts power. The 4-pins ATX power male connector is coupled electrically with the CPU socket.
