ATX Power Supply
The more recent models of the ATX are more power efficient than their previous models. ATX 12V design has substantially improved the power efficiency which was previously missing. The power supply is up to seventy percent efficient in the ATX 12V. The current power supply cable used in the ATX motherboards is a 20 + 4 pin combination.
It is the industry standard that is being followed by just about everyone and has been working well for almost two decades now.

BTX Power Supply
The BTX motherboards are designed in a manner to take less space in comparison with other motherboards. They also have better heating control systems in place which allows for better performance and less energy loss to make the motherboard more power efficient.
The idea was introduced by Intel and was first manufactured by Gateway, Inc and then Dell and MPC. Some of the elements are followed by the Apple’s Mac Pro as well.
It incorporates a 20 + 4 pin power input.
