Is my system ok?

[mathieu.du.jardin]

RTX 2070 Founders Edition
i7-9700K
Gigabyte Z390 Aorus Elite
2x8GB DDR4 3000MHz
Noctua NH-D15S
Corsair HX750 Platinum
NZXT H500

Is this a good gaming rig? And is my psu also good for future upgrades or should I have bought a HX850 Gold?

Should be a solid rig for several years
