The Continuum is an 'okay' supply if you can get it on heavy discount, I'd have a problem buying a platinum rated unit that only has a 5 year warranty however. Even mid range Seasonic's and similar have 7-10 years minimum, I'd rather go with the company that has faith in it's product.
All my other supplies are Seasonic Personally if it's in something I care about they are the only brand I buy. The continuum has run 13gpu's (rx550/rx560 level cards) just fine for over two years so given that load I think it will be fine in my mrs little 2700x machine.
