Abstract

The invention discloses a double-power expansion card of a computer, which comprises a computer expansion slot fixing baffle plate, a circuit board, a computer power supply 20 PIN socket, computer power supply 20 PIN plugs with a certain length wire, a diode, a resistor and the like. The expansion card is fixed on the computer expansion slot fixing baffle plate by a bolt; the two computer power supply 20 PIN plugs are connected to the expansion card at the same time; and the computer power supply 20 PIN plugs on the expansion card are connected to the computer main board, which can start up or power off two computer power supplies connected to the expansion card at the same time when a computer power button is triggered. One of two power supplies connected to the expansion card mainly supplies power to the main board, and the other one mainly supplies power to peripheral devices, such as a hard disc, a CD driver and the like. According to the invention, one large-power power supply can be replaced by two computer small-power power supplies.

Description

technical field [0001] The invention relates to a computer power supply connection device, in particular to a computer dual power supply expansion card. Background technique [0002] At present, there are more and more devices connected to the computer, such as multiple hard drives, multiple optical drives, high-performance graphics cards, multi-core CPUs, printers, scanners, mobile phone chargers, and even electric coasters, etc. Computer accessories are constantly being added and upgraded. Higher requirements are put forward for the power supply, and the output power of a power supply is always limited. The power of a normal computer power supply is between 200W-300W. For a large increase in power consumption, there are often problems with computers due to power failure. Crash and other failures. Purchasing a high-power computer power supply is indeed an effective solution, but the cost is high. At the same time, the replaced power supply becomes electronic waste, and the...
