Yup, it's OK to put a 20 pin in a 24 pin hole.
Pin 1 goes to pin 1, leaving four empty pins bunched
at one end of the connector. The "shape" of the
nylon shells, helps check the alignment of the
proper pins.

Using a 24 pin connector, is more important if you are
installing two PCI Express video cards. If only
one PCI Express video card is present, then for the
most part, the 20 pin supply connector is good enough.

The 20 pin connector has one 12V wire. The 24 pin
connector has two 12V wires. That increases the room
for current to flow, when something in the motherboard
needs more current. Some video cards draw 12V @ 4A through
the video slot, and when two of those cards are present,
and 8 amps is being called for while 3D gaming, that is
when the 24 pin power supply is a better choice for power.

Thanks, well explained, but I hear there are also adapters, can those
do the job for two pci-e video cards and a 480 watts power supply?

Very, very unlikely. The older PSUs foccussed on 3.3V and 5V
power. The new ones put most into 12V. Get a new PSU. The
cost of the 4 (!) adapters needed will be wasted.
