Abstract
The invention relates to mainboard which comprises a PCI-E expansion card and a signal transfer card electrically connected with the PCI-E expansion card. The mainboard is provided with a first voltage end and a second voltage end. The signal transfer care comprises three slots. Each slot is electrically connected with the first voltage end and the second voltage end. The PCI-E expansion card comprises three available ports. The three available ports provide first voltage and are electrically connected with the second voltage end. The mainboard further comprises a power connector which provides second voltage and is electrically connected with the first voltage end. By the mainboard, the same signal transfer card can support one display card and two network cards at the same time.
Description
Technical field
The present invention relates to a kind of motherboard.
Background technology
At consumption electronic products as in PC, if video card etc., network interface card etc. are directly inserted on motherboard, then can take the height space in main frame, now, general install on motherboard one can horizontal positioned signal switching card thus reduce the height of main frame, the height of whole electronic product is compressed further, to meet the demand of user to miniaturization.Existing signal switching card is directly by the PCI-E slot power of motherboard, according to the specification of PCI-E, motherboard is maximum provides the power supply of 75 watts to signal switching card, on a signal switching card, support the network interface card of the video card of 75 watts and 15 watts or 25 watts if want, the power supply on motherboard cannot satisfy the demands simultaneously.
Summary of the invention
In view of this, be necessary to provide a kind of motherboard that can meet power demands.
A kind of motherboard, it comprises a PCI-E expansion card and a signal switching card be electrically connected with this PCI-E expansion card.This motherboard have first voltage end, second voltage end.This signal switching card comprises three slots, and each slot is all electrically connected with this first voltage end and this second voltage end.This PCI-E expansion card comprises three vacant ports, and these three vacant ports provide one first electricity and are electrically connected with this second voltage end.This motherboard also comprises a power connector, and this power connector provides second voltage and is electrically connected with this first voltage end.
Motherboard of the present invention, by three of PCI-E expansion card vacant ports are accessed first voltage, second voltage is provided to increase power supply to these three slots by a power connector again, can realize on same signal switching card, support a video card and two network interface cards simultaneously, this motherboard namely can be made to meet power demands.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of motherboard provided by the invention.
Main element symbol description
Following embodiment will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described in further detail.
Refer to Fig. 1, a kind of motherboard 10 that embodiment of the present invention provides, it is in the electronic products such as PC, and this motherboard 10 comprises a signal switching card 11, PCI-E expansion card 12 and a power connector 13.Wherein, this PCI-E expansion card 12 is a PCI-E X16 expansion card.
This motherboard 10 has a first voltage end U1, the second voltage end U2 and auxiliary electrical pressure side U_AUX.Wherein, the voltage of this first voltage end U1 is 12 volts, and this second voltage end U2 draws from the bus plane of this motherboard 10, and the voltage of this second voltage end U2 is 3.3 volts, and the voltage of this auxiliary electrical pressure side U_AUX is 3.3 volts.
This signal switching card 11 comprises a first slot S1, the second slot S2 and a 3rd slot S3.This first slot S1 and the network interface card of this second slot S2 all for plugging 25 watts, the video card of the 3rd slot S3 for plugging 75 watts.
This PCI-E expansion card 12 comprises 16 port P0 ~ P15 and three vacant port Pa, Pb, Pc.These 16 port P0 ~ P15 are electrically connected with this first slot S1, this second slot S2 and the 3rd slot S3 respectively.Particularly, port P0 ~ P3 and this first slot S1 of this PCI-E expansion card 12 are electrically connected, and port P4 ~ P7 and this second slot S2 of this PCI-E expansion card 12 are electrically connected, and port P8 ~ P15 and the 3rd slot S3 of this PCI-E expansion card 12 are electrically connected.Three vacant port Pa, Pb, Pc provide first voltage, and are all electrically connected with this first slot S1, this second slot S2 and the 3rd slot S3, provide power supply for giving this first slot S1, this second slot S2 and the 3rd slot S3.In present embodiment, three vacant port Pa, Pb, Pc are all electrically connected to this second voltage end U2, and for strengthening the voltage of this second voltage end U2, the value of this first voltage is 3.3 volts.
First voltage end U1 and this first slot S1, this second slot S2 and the 3rd slot S3 are all electrically connected, this the second voltage end U2 and this first slot S1, this second slot S2 and the 3rd slot S3 are all electrically connected, and this auxiliary electrical pressure side U_AUX and this first slot S1, this second slot S2 and the 3rd slot S3 are all electrically connected.
This power connector 13 is all electrically connected, for providing second voltage to this first slot S1, this second slot S2 and the 3rd slot S3 with this first slot S1, this second slot S2 and the 3rd slot S3.In the present embodiment, this power connector 13 is a 6PIN power connector, and this power connector 13 is also electrically connected to this first voltage end U1, and for strengthening the voltage of this first voltage end U1, the value of this second voltage is 12 volts.
Be appreciated that these three vacant port Pa, Pb, Pc also can provide this second voltage to be then electrically connected to this first voltage end U1, for strengthening the voltage of this first voltage end U1.And this power connector 13 can provide this first voltage to be then electrically connected to this second voltage end U2, for strengthening the voltage of this second voltage end U2.
