    I mean, it should be fine, just because the PSU can provide more watts doesn’t mean the system is actually using that much power. I have an 800w PSU in my gaming rig, but its average load is only 240 - 320w during gaming (I’ve measured it by powering the system with a portable Ecoflow battery).

        Where are you getting this from? Intuition?

        I think the quiescent current and losses are less in a well engineered psu.

          This is verifiable in manufactures data sheets.

          Efficiency at less than 20% and greater than 80% loads isn’t great relative to in between those ends.

          This is compounded by lower wattage PSUs being more limited with regard to features and benefits.

          If you end up with a 650w PSU and your system idles at 80 watts for the bulk of a working day you spend long periods of time in this less efficient window.

          We need to see some quality 300w to 600w designs come back onto the market.
