MP3DP -- best way to connect wires to power terminal

i got 10 awg wire today to rewire my power supply to the ramps 1.4 board.

i got the wire secured on the power supply but the green power terminal to wire into just cant handle the thick wire.

what would be the best way to connect this wire to the terminal? would a bullet terminal connector work?

also would the c shaped terminal connector be better to connect to the power supply?

thanks

I use cord end terminals for my power supply/RAMPS connection -> http://amzn.to/2fAuolv and ring terminals to power supply
