Electronic device

An electronic device comprising:

• a chassis comprising a base and a first side plate, the base defining an opening;
• a circuit board attached to the base;
• a first connector attached to a back surface of the circuit board;
• a power supply, located between the circuit board and the base and substantially perpendicular to the first side plate;
• and a second connector attached to the power supply;
• wherein the second connector of the power supply is configured to slide along a direction substantially parallel to the circuit board to electronically connect to the first direction;
• in a first position, the second connector is electronically connected to the first connector, and the first side plate is attached to the base to cover the opening;
• in a second position, the second connector is removed from the first connector, and the first side plate is disengaged from the base to expose the opening;
• the base comprises a first retaining panel, a second retaining panel, and a third retaining panel located between the first retaining panel and the second retaining panel, the first retaining panel, the second retaining panel, and the third retaining panel cooperatively define the accommodating space, and in a third position the power supply is received in the accommodating space, wherein a cutout is defined in the third retaining panel, the cutout being adapted for the second connector to pass through, wherein the power supply comprises two sliding portions, one sliding portion abuts the first retaining panel, and the other one sliding portion abuts the second retaining panel, wherein the base comprises a sliding slot and a positioning block adjacent to the sliding slot, the first side plate comprises a sliding tab, and the sliding tab is slidably received in the sliding slot and abuts the positioning block.
