    You do not need anywhere near 720W, unless you've got dry ice or liquid nitrogen cooling and are benching for world records...
    Where are you buying from? Link some shops that are convenient for you, if possible...

    None of them are great but the RM is better because ripple suppression on the XT sucks
    Cant you find anything else?

    But as said above you dont need anywhere near 700 watts a 550 watts PSU is all you need

    I don't mean to be rude, but you already have a thread asking this question. Try to keep it to one place, just as many people will see it.

    Hey everyone,

    I'm looking for a decent PSU but there's so many on the market now and I've been out of the game for a little while. I've been rocking my TX 850 for about five years now so it's definitely time for a change!

    The most critical thing is that I need a PSU which is super-quiet, if not silent. As in, as-quiet-as-a-ladies-wind kind of quiet. ;)
    I've been leaning towards the Be Quiet! 800w, which seems like it might fit the bill. Are there any other major players I should be looking at?
    And are there any decent passively-cooled PSU's on the market? I recall seeing some a few years back.

    Current rig is a Gigabyte x58a-UD7 with an i7 920 (Ancient, I know... they'll be getting the boot soon too. ;) ) and a GTX 970.

    Thanks in advance..
    /Mick

    @roast Seasonic has a 560W fanless model. Here it's about €150, FSP has a fanless 500W unit for about €130. If you want more power, the big EVGA 1600W Supernovas will do more than that in fanless mode, if you have a well ventilated case.;)

    Depends on exactly what video cards you try to run with it. 700 watts is not enough for 290X crossfire, although it is plenty for a single 290X. Personally, I wouldn't try crossfire 290X with less than 850 watts. 290X is a very power hungry video card.

    thanx for response.

    actually i meant for single 290x and this is extreme power draw i know and if centauro 700w can handle single easily 290x this means, it will a good future proof option. thats why i mentioned 290x single for reference. OK. and what about 280x CFX on this PSU, would be a good enough??? just in case

    Depends if you're planning on running Furmark on them. Then it will not be enough as that has 50W on the 12V line = 600W which those cards will attain. Honestly I would not do it, and I'm very liberal in my PSU recommendations.

    I've always felt that 50% to 80% of max as a good target. I start having concerns if you end up needing to run a PSU above 80% of max. Some quality single-rail PSUs can be good, like Seasonic and many corsair units. While the Xigmatek @The N described is a single rail PSU, I can't say anything for the build quality. I personally wouldn't go less than 850 for 290X crossfire.

    It's decent, but only 50A on the 12V rail. I probably wouldn't go under 850W even for 280x crossfire on the odd chance you want to run Furmark for funsies. It's not a realistic load, but still.

    OH, 700w centauro is outta stock right now. now i am going for Centauro 800w PSU, with 58A @12v . with difference of 1K new price. in our country, can't find many brands. i only find xigmatek in my range with good specs ad review. corsiar is very expensive

    oh people, while i was focussed on xigmatek to buy and with no other options. suddenly i received an offer of be quiet 750w 80+ GOLD, Modular, used though. so i bought it wihtout any thought as i already read its review and it seems very very efficient due to GOLD rated and future proof.

    I would rather take the Zigmatek PSU. At least it only has a single +12v rail where the Be Quiet has 4. Despite efficiency, I think the Zigmatek is the better choice.

    Just keep an eye out on how you plug stuff in on the rails and you'll be ok.

    EDIT: Don't run furmark on the 280x's btw.
