    28,000,000 watts

    That’s usually written as 28MW. I know some Americans don’t like metric much, but one of the points of metric is that you don’t ever need to write that many zeroes - you just need to use the right prefix (kilo, mega, giga, tera, etc) on the unit.

      True, but 28 million watts really puts things in perspective when your average PSU is less than 1000w.

        Exactly. This is literally a PC gamer article. Writing it out like that really puts it into perspective for the average reader.

        That’s true.

        average PSU is less than 1000w

        Unrelated but I wish it was easier to find lower-wattage PSUs. My local PC store doesn’t have anything under 650W. I know modern GPUs use a lot of power, but not all PCs use a GPU! I have a home server where 400W would be more than enough, yet the smallest I could find was 550W, in stock from just one manufacturer (Be Quiet).

          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.

                  Well, it depends on how much you’re spending: 80 plus titanium units, for example, are 90% efficient at both ends of the spectrum, which is as good as a 80 plus gold unit at the ideal 50% load.

                  Of course, they’re expensive, and thus maybe not really the best solution since the wasted power is probably never going to add up to the cost of the better PSU, but there is enough of a demand for high and low load efficiency that it’s a thing that you could go buy.

      you just need to use the right prefix (kilo, mega, giga, tera, etc) on the unit.

      Oh, thanks.

      Bruh, it’s PC Gamer.

      quick edit: Hey! Why aren’t you converting it to Joules?

        Because Joule is the SI unit of energy, meanwhile the Watt is the SI unit of power, equivalent to one Joule per second.

        “Converting” joules to watts would be like converting m/s to US dollars.

          I liked the analogy but I do think it would be clearer to say something like joules = money in bank account and Watt = spending per second
