I have had a good look around for how much power my PSU's are using and have got some quite weird answers. One in particular said that the mains power usage / current draw is around half of what the PSU puts out.
Now using that logic my latest - Corsair HX 1050 rated a bit below that figure it turns out would be drawing 400 -- 450 watts from the mains supply? This I find very hard to believe in view of the technology and having made a few battery chargers in my time I have never seen those sorts of figures before.
So does anyone know what mains power PSU's actually use? I know a device will only reflect the input by what it is putting out even so with the cost of power as it stands using my machines could be very costly.
