Using a 20 pin Powersupply on a 24 pin power connector on a motherboard?

I notice the cheaper computers with inexpensive $10 power supplys only have 20 pins on the PSU main power connector, but they use a 20 pin power supply on a motherboard that have 24 pins on the motherboard power connector port. When the PSU is plug in there are 4 empty power ports on the mobo.

The computer boots and run fine.

What is the major disadvantage of using a 20 pin PSU on a 24 pin Motherboard?
