Soldato
Indeed but they've been using CWT for ages, it isn't anything new really, maybe a bit more often than not. You do tend to pay for the longer warranty, customer care etc and frankly a lot of OEM snobbery is just that, means very little for the low to mid range build.
XFX are good value due to the Seasonic OEM, but make sure to deal with the retailer as their customer care is atrocious.
OcUK Do over 28 Days support for both and under 28 Days for XFX anyway...
