Abstract

The invention discloses a power supply device which comprises a first power conversion device and a second power conversion device which is arranged outsides the first power conversion device and is electrically connected with the first power conversion device, wherein the first power conversion device is used for converting voltage of household electricity to first direct current voltage and transferring the first direct current voltage to the second power conversion device, and the second power conversion device is used for converting the first direct current voltage to at least one second direct current voltage and outputting the second direct current voltage. In the power supply device, compared with the power supply device in the prior art, the volumes of the first power conversion device and the second power conversion device which are arranged in a split way are relatively reduced, and the first power conversion device and the second power conversion device can be respectively installed at different positions in a crate so that the internal space of the crate is fully utilized; and furthermore, when the power supply device is detected, the first power conversion device and the second power conversion device can be respectively detected, and therefore, fault judgment is easier, and the detection process is very convenient.

Description

technical field [0001] The invention relates to a power supply, in particular to a power supply used in a computer. Background technique [0002] The power supply in the computer is used to convert the voltage of domestic electricity into different voltages suitable for various electronic components in the computer. The power supply includes a casing, and a first voltage converter and a plurality of second voltage converters arranged in the casing. When the power supply is in use, the first voltage converter converts the domestic electricity voltage, such as 220V voltage, into 12V voltage, and then converts the 12V voltage into 3.3V voltage through the second voltage converter. V, 5V and other voltages are used to supply different electronic components in the computer, such as CPU, hard disk, etc. [0003] However, this kind of power supply integrates many voltage converters, which is bulky and takes up a lot of space, and cannot adapt to the trend of miniaturization of co...
