    Default Swapping out a noisy Corsair 750HX. Good alternative?

    Hello Guru's!

    I have been happy with my PSU so far, but after having tried getting my PC to be silent, sadly it is no longer so. After buying a Corsair Obsidian 550D case and 4 Noctua Redux NF-S12B 700 I found out that the fan-noise that was bothering me was actually coming from the PSU. Yes, I should have checked before buying but I really wasn't expecting the PSU to be louder than 4 cheap 120mm fans + a Noctura CPU fan + a graphic-card


    A bit of googling and it turns out it is a known problem of Corsairs

    What would be a good alternative in the same price range that is (more) silent?

    PC specs:
    * ASUS Sabertooth P67
    * 8GB RAM
    * Intel Core I5 2500K
    * GIGABYTE GeForce GTX 760 OC
    * 4 case fans
    * DVD-RW
    * 2x SSD's

    I'm located in Denmark and usually use this site.

    Corsair HXi for example, but do you really need 750W?

    There are several ones: if you may state rig specs and location we could try to advice you better.

    Would a Seasonic Platinum Fanless Series - 520W be enough I wonder?

    I really have no idea how much I need. Using a online calculator I get 450-550w depending on age. So 520 isn't enough is it?

    Seasonic Platinum Fanless 520W is more then enough, but isn't the be quiet! Straight Power 10 400W available in Denmark?

    It is: http://www.pricerunner.dk/cl/640/Str...+power+10+400w much better buy imo.

    Which would you recommend if it had to be modular? I'd rather not have all those cables

    With a case like the Corsair Obsidian 550D, a modular PSU isn't really a plus, all the cables you don't gonna use can easily be put behind the motherboard tray. Your also gonna use all cables or all with the exception of one. So its not really useful if you ask me.

    The only useful thing will be a full modular PSU, so you can easily take it out for dedusting. So you can get a Corsair RM450, but it's worse quality wise.

    If silence (and build quality) is paramount, that one will be one I would look at: http://www.edbpriser.dk/stroemforsyn...d-6334375.aspx

    Alternatively (and of slight lesser quality): http://www.kelkoo.dk/ss-be-quiet-500...-power-10.html

    Among the cheaper but quiet (given an expected power draw around 230W while gaming) I'd give a look at:

    http://www.proshop.dk/Stroemforsynin...U-2430897.html

    Which one is better suited for your needs, price-wise?

    P.S.: performance-wise a Seasonic Platinum is better than any other option I quoted.

    Denmark isn't far from here.
    I just need to drive to the nearest port (about 15km) and take a ship...

    Besides that:
    For THAT, a good 400W PSU like the Straight Power E10 is more than enough.
    If you want to overclock, you may want a 500W PSU. But no more...

    If your GPU is too slow, sell it and buy a new one...

    Hey, we're talking about one, maybe two cables you may save with CM...
    So IMO it's not really worth it. You may want to save a buck or two for other things...

    For example, a 500W Straight Power has:
    1 ATX connector (needed)
    1 CPU 4+4 Connector (needed)
    2 PCIe 8pin cables (both needed).
    3 Peripherial connectors. You need one, eventually a second one...

    So one or two cables may be hanging 'round in your case.
    But for that you could use zip ties (some are delivered with the PSU if I'm not mistaken)...
