Thanks for the heads-up would never compromise with PSU brand or quality. Out of these brands which one is good in terms of after sales (especially RMA). I remember my Seasonic one was acting up at the end of its warranty life and getting it replaced without any  hassle.

All of the above mentioned most likely will be good, since these are considered to be reputable brands.
However I don't know if one of them sucks at after sales services or one is really good at it so it's also a good option to do research on their after sales service.
Going with a brand you have already used is a great option since it can bring a sense of reliability.

However speaking of their wattage output, the 550 watt nzxt will be fine, just barely.
Though the deepcool one seems to be a great option since it has 80 + gold and 10 years of warranty. Also with deepcool, you can upgrade to a wattage monsters like the 9070 xt or the 5070 ti.

Though always your call.
