Power supply device and computer system

A power supply device, wherein the power supply device comprises a first contact and a second contact;

• the first contact is configured for electrically connecting a conductive interface of a power supply end and the second contact;
• the second contact is configured for electrically connecting a conductive interface of the power supply end and a power interface of a server;
• wherein a length of the first contact is greater than a length of the second contact, so that, during insertion of the power supply device into the power supply end, the first contact makes contact with the conductive interface first to raise a voltage of the second contact in advance, and then the second contact starts to connect with the conductive interface to supply power to the server;
• wherein the power supply device further comprises a current limiting circuit, and the current limiting circuit is connected between the first contact and the second contact;
• the power supply device further comprises a filter energy storage circuit connected to the second contact, the filter energy storage circuit comprises a filter capacitor for storing and filtering a current transmitted to the second contact via the current limiting circuit;
• the power supply device further comprises a bleeder circuit and a logic control circuit;
• the bleeder circuit comprises a bleeder switch, and three ends of the bleeder switch are respectively connected to the second contact, the logic control circuit and a ground end;
• and
• the logic control circuit is configured for controlling a switching state of the bleeder switch, and current in the filter capacitor is discharged when the bleeder switch is turned on.
