Questions about this item

What type of motherboard connector does the KHACHIMO 300W ATX Power Supply use?

It uses a standard ATX connector, so any motherboard with an ATX power socket will accept it.

Will this 300W unit run an older system that still uses a 20-pin main power plug?

The supply follows the ATX form factor; if the older board uses a 20-pin ATX plug it will fit, while boards with the newer 24-pin socket accept the same connector with the extra 4 pins left unconnected.
