Question Looking for basic reliable psu around $100; SF Leadex3, Corsair RMX, Other?

[Coyle]

I just have a simple build, i3-10100, Asus rog strix B460, no gpu yet but won't be anything more power hungry than an RX570 4GB. I'd purchased a CX650 that was DOA. I just want a quiet reliable psu that's not likely to fail on me. The ones I've found that are in my price range and in stock are Super Flower Leadex 3 Gold 550W, and Corsair RM650X Gold. But I'm flying blind, reading threads, reviews etc. Is one of these better than the other, or is the a better psu for the price, and that's in stock?
Thanks.
