Both are extremely good quality.
Seasonic is a manufacturer which makes top of the line PSUs when it comes to quality.Seasonic also makes the XFX PSUs,so they're great quality too.
You can't go wrong with either of them.

A power suply has no effect on frame rates. It is either capable of providing enough power to components and you get the same performance out of any of them or it is not and you get random crashes, reboots, display corruption and various other issues.

RAM only uses 2-3W per DIMM so it is pretty much inconsequential for PSU selection.

The Seasonic one is top quality,while the others are great too.
They definitely won't cause any reboots or stuff like that.
And yes,it is compatible with your build. -_-

All GPU manufacturers grossly overstate their cards' requirements because there are tons of sub-par PSUs in the wild that cannot reliably deliver more than about half their stickers' ratings.

Even the R9-290X only peaks at 350W. Add 150W for a typical worst-case for the rest of the system, you get 500W. Add a 50% safety margin on top of that, you get 750W.
