Example implementations relate to power supply chassis. For example, an apparatus may include a power supply chassis. The power supply chassis may include a handle and a sidewall defining a latching slot. The handle may include an inner slot. The apparatus may also include a release lever to slidably connect to the handle via the inner slot. The release lever may include an engagement tab. The apparatus may further include a latching member in physical contact with the engagement tab. The latching member may include a latching fang. The release lever may control a position of the latching fang relative to the latching slot via a rotation of the latching member.
