Just talked to my supplier and since the crappy one is still under warranty
they've agreed to replace it with anyone I choose.
I can pick from any of these:
(They have Corsair, CoolerMaster, Chieftec, Gigabyte, LC Power)
I'm mainly looking at Corsair:
Which would you recommend for my system?
More importantly, as the supplier is replacing your faulty LC Power (LegionX v2.9 1050W), I suggest to pick the most powerful quality PSU that they allow you to choose.
Among the four listed, HX650 is the best (better features than the TX650: modular, a little bit more quiet, 2 more PCIe connectors, longer warranty...etc)
