    I already have 600W, im glad if it getting better, more performance i hope with same thermal footprint, but who knows, we need more reviews of these components..

    Well, Titanium means efficiency 90 - 94%.
    If PSU is running at 600W this means 36W is lost as heat. Ok, it is not lost in single device but x570 chipset is 15W and has fan for cooling.

    Cause PSU does not have fan it relies on case to provide cooling what will be difficult with some cases. Eg my Fractal has almost isolated PSU at bottom.

    Nice to see fanless design.

    But without a little airflow, temps tend to sooner or later get out of control.

    An optional super low rpm, like 500rpm, will be completely silent and lower the temp by a good margin.

    Yes you are right , although you did not factor in the surface the x570 is a tiny chip and all 15 watts are all "cramped" over there , meanwhile the heat generated on a psu is not on just one component so the surface and volume in the psu to absorb the heat are vastly bigger in a psu , also depends how big of a heatsink you can smack on to of those .

    I have the PSU in my Define 7 mounted with the fan up, and it never spins up. While it did spin up with the fan down.

    So i'm sure a Fanless PSU will work fine there as well.

    Just buy a case with a vented PSU shroud.

    I need a fan to move the dust around.
