    Seems odd that the fan is controlled by the amount of load on the PSU and not the temperature, wouldn't it be better to not run the fan until X temperature is reached rather than X load. What happens if you live somewhere really hot, will the PSU cook its self ?

    The 750W one is the sweet spot in terms of price:

    Power (W) Price (£) W/£
    450 78.95 5.70
    550 86.99 6.32
    650 92.99 6.99
    750 99.95 7.50
    850 124.99 6.80
    1000 149.99 6.67

    which is handy as that's one I'm looking at.

    The website states that thermal sensor controls the fan speed.

    Perhaps it is pre-emptive: once it passes 40% load the temperature starts going up and they want a smoothly flattening temperature curve rather than a sudden shock of cooling kicking in.

    I like the sound of passively cooled power supply. You could get a higher than needed one and have it passively cool most of the time.

    There's plenty of possible reasons to use load instead of temp. The sensor may not be effective at lower temperatures due to passive cooling elements. So sensor doesn't read anything until a certain heat level is reached but you want to kick the fan in earlier than that. Heat /electrical power, its all watts anyway.

    Another could be purely marketing. People are more used to dealing with load rather than heat when it comes to the psu. Whats hot cool or normal temps for a psu?
