I tried to just use the 20 pins and plug the 4 pin the cpu slot and nothing happens.
Take that 20 pin +4 connector and put it into the main slot.
Make sure your 4 pin atx connector is inserted in properly.
Check your case wires closely, one for pwr, rst, led and hdd.
Take your pwr and connect it first, power on the machine.
If nothing happens, you have the wire in reverse, flip it and reinsert.
Once you here it fire on, shut it down after 10 seconds and do the rest of the wires correctly/
For the record, please specify which psu model brand you have.
Look at the label on the psu and look for the model number.
