It's just enough. However I wouldn't keep the system overclocked or push GPU power limits.

However, given how cheap an RM850x is, you should consider whether it's really worth economising.

Would the corsair rmx750 also be a good choice?

One thing about the Corsair RMx series I don't like is the cables. Mine is the 2021 version and the cables are ugly, bulky and very stiff. It's impossible to get a tight bend on the 24 pin and 8 pin EPS due to the stiffness and bulk because of the added capacitors so I am using my braided extensions again. No wonder people pay silly amounts for aftermarket cables!!

Any recommendation for the after market extension cable?
