some manufacturers claim 1000w minimum, others 850w minimum.
check for this particular model and see what ASUS recommends.

i would try some stress testing with the current unit and see if any problems arise.

At least get the Corsair 12VHPWR cable https://www.corsair.com/eu/en/p/all...5-0-12VHPWR-Type-4-PSU-Power-Cable-cp-8920284

The RM850x is not a ATX3.0 unit so it will shut down @ 1100w but I don't expect this to happen.

If it's too close to the limit, it will affect the efficiency of the PSU. And the noise.

Buy a 1200w high end PSU.

This also depends on what CPU your using, if it's a fairly low power draw then your probably OK / borderline if it's a power hog your probably not.

I put absolutely zero stock in what the manufacture says is needed because they have no clue what the rest of your PC parts are.

https://pcpartpicker.com/product/Nf...lly-modular-atx-power-supply-titan-gold-1200w too, is at least as good as and doesn't even cost half of the Seasonic. The Seasonic is way to expensive.
