In some aspects, power supplies for liquid cooled plasma cutting systems configured to support plasma arc generation by a torch head connected to the power supply can include: a set of electrical components for plasma arc generation; and a power supply housing containing the set of electrical components, the power supply housing having a front panel and at least two side panels and defining: a set of inlets for allowing a cooling gas to enter the power supply housing to thermally regulate the set of electrical components, at least one inlet of the set of inlets being positioned at a corner of the housing and oriented at a non-zero angle relative to the front panel and to at least one of the two side panels; and a set of vents for allowing at least a portion of the cooling gas to exit the power supply housing.
