Looking for a PSU for the AMD build for gaming. removed link

I tried a Corsair RM 850x but had some issues with the computer not powering on and it making some squealing noises. Decided to return it in the 30 days.

I was going to order a Supernova 850 T2 based on the cybernetics report but I feel maybe that’s not the best idea due to,it’s age and it’s 180mm in length which is not leaving a lot of room for cables on the Torrent Compact case. I know I can make it work if I had to.

based on a few reviews I am trying to decide to go to smaller psu of the EVGA 850 G7 which had good reviews here and on Toms or the Seasonic Focus px-850 which I’ve only found the cybernetics report and a Russian review. My other though is to go with slightly shorter Antec Signature 1000 titanium or the Seasonic prime tx-1000 which are both available to me in Canada. 
Any help narrowing it down would be great. I know I don’t need a 1000w psu really and it’s as high as I want to spend at just under $400 cdn.
