Getting a new PC (from CyberPower), and fear i may have messed up with the PSU (have read the stickies)

I am in the midst of buying a new PC and am a bit limited in what this place offers for PSUs. I will post my build, and the options, but if they all suck, I AM willing to buy a separate one in person and replace their stock one if need be, but would be easier on me if one of these qualified as I am forced to pay for at least their stock, which reviews say are terrible, so is cheaper on me if i can replace it with them. I will add I have already ordered (Friend of mine told me the stock PSUs were fine, then i did some reading, this is on me) so I am calling them tomorrow to see if they will let me swap it out (as I only ordered on friday). If not, then I will have to pay for another and install it myself.

Also to note, I am Canadian, so conversion is a thing i have to keep in mind, plus shipping for anything i order from the states.

IN CONCLUSION:

I am not on a SUPER tight budget, but have already dropped a fair bit, so i don't want to go crazy with the PSU. having read the stickies, and a bunch of reviews, my plan right now is to try and get the EVGA SuperNOVA 1050 sale price, and if I cant, get the Corsair RMi Series RM650i instead, and if they won't replace it at all, then i will have to figure out what to buy in person. But of course I am posting this because I want to hear what you have to say! Thanks for your help!

*EDIT*

I want to note I recognise that for a single card set up, 1050 is WAY overkill, but if i can get the sale price, it is CHEAPER than the RM650i
