    Another question - Quietest PSU?

    Now that I've got quiet case fans, my gfx card has a zalman fan, my processor has Arctic Pro 7 on it, my PSU is by far the loudest thing in my box. It's a coloursIT 700w
    I've got e6750, 8800GT, 2 SATA HDD, so between 500-600w?
    I'd like to keep it between £50-60 if possible.


    Thanks in advance

    The corsair's are supposed to be very quiet, not that i have one, just what people say. I have a silverstone Zeus which is the quietest thing in my case, even though the leafblower on my 3870 drowns eveything else out.

    Re: Another question - Quietest PSU?

    The corsairs are certainly very quiet. The 520W HX is great at it's price, modular as well. You won't hear it above anything else, I don't think i've ever heard mine lol

    The quietest would either be one of the zalman fanless jobbies.. or the the new Enermax modu82+ (or something like that) which silentpcreview hailed the quiestest of them all (that have a fan)

    Re: Another question - Quietest PSU?

    I can vouch for the Corsair HX PSUs too, inaudible when operating alone.

    The Seasonic S12 series are very quiet too. In fact Seasonic make the HX PSUs for Corsair.

    Re: Another question - Quietest PSU?

    I've never heard my Seasonic S12 - in fact the fan is slow and the air out is 'luke-cool'.
    To keep quiet the PSU needs to be of good quality (so that the ratings are true) and run at <50&#37; loading (although this might vary according to make and model) so that the fan stays on its lowest speed.
    However, the efficiency of a PSU is at its ~80%+ level between about 20% and 80% of rated load, so there might be a trade-off. (My S12 is 330W but the system on idle is about 45W input so the PSU is only about 10% output - couldn't find a good PSU lower than this with a decent 12V rail).

    I've got the Corsair HX 520W, and it's very quiet, modular and very stable.
    Cave canem!
