I replaced my power supply, do I need to check anything else?

I know this is a stupid question... but im new to all the computer building and this was my first time replacing my old power supply cx600 with a 750w toughpower grand rgb.

Everything is working fine, the power supply turns on, motherboard on, graphic card on, cpu on, ram on, sata, it's running just like a normal computer. I did the cable management as good as I can to make it neat and everything. I was just wondering do i need to check anything else incase I might've screwed up or doing something wrong, I'm just scared that the computer can turn off any moment.

I have a deepcool kendomen case which I installed the power supply into.

I would stress test the computer. Just booting up Windows is fine, but that won't put a load on the new power supply. Run something that makes the videocard work hard, then you'll know for sure everything is okay.
