    Corsair has been making PSU since the second half of 2006…
    They unveiled two appetizers to market, 520W and 620W PSU.
    The performance and product specification is really great.
    I knew some users take them to compare with Seasonic’s M12 series.
    No matter the spec and appearance, both of them have something in common.
    Hence, I analyze them by a comparison.

    Price is always significant to consume, so:
    Seasonic M12 about US$148
    Corsair HX520W about US$121
    If you are the users who care about quality,
    guarantee period and reasonable price, Corsair HX520W might be a better choice.

    The Corsair HX520W Modular Power Supply
    We take a look at the package first, it’s a bit bigger than some “same-level” product.

    Corsair HX520W itself

    The major heat dissipating system is the 12cm temperature-control fan.
    The RPM is low when light loading. If in a heavy loading situation, the noise is still acceptable.
    [​IMG]

    There is a cellular heat dissipating “holes” for a better heat-dissipation.
    It is a “auto-switch”, no need to put a 110/220v switch there.
    [​IMG]

    12V x 3, up to 54A, 480W
    That can support most of mid-range to entry-level high-end VGA,
    which under SLI/ Crossfire mode without problems

    A modularized sockets: 24/ 8/ 4pins
    [​IMG]


    CPU:INTEL Core 2 Extreme QX6800
    MB: DFI LANParty P35-T2R
    DRAM:CORSAIR Dominator TWIN2X2048-8888C4DF
    VGA:ELSA FALCOX HD260XT 256B3 HDT RH
    HD:Seagate 7200.10 320G
    POWER:Corsair HX520W Modular Power Supply
    Cooler:Thermaltake V1
    [​IMG]

    The settings under OS:
    CPU: 333X10=>3333Mhz
    DRAM: DDRII 1000 CL4 4-4-9
    VGA: 2X ELSA HD260XT
    The voltage of DFI P35 is a little low, that’s because the power consumption is keep on.
    [​IMG]

    OCCT is an useful testing software
    In the test, it can make all the cores in a full-loading status

    The variation of the CPU’s voltage is more related to motherboard’s design.
    The performance is good if the voltage can reach 1.3 to 1.34V while all cores is full loaded.
    [​IMG]

    3.3V: about 3.22 to 3.25V, the voltage “drop” about 1% only
    [​IMG]

    5V: about 4.76 to 4.81V, also, the voltage “drop” about 1% only
    [​IMG]

    12V: it sticks in 11.9V
    [​IMG]

    OCCT is mainly for testing the voltage (3.3/5/12V) variations of CPU and RAM while under OS full-loaded.
    For some minimal error of mobos or high-end VGA cards, it is not for it.

    The PSU works fine with quad-core CPU and 2600XT CrossFire in a OC situation.
    In the test,
    The RPM of the fan is not high and the working temperature is acceptable too(around 40C) includes all the merits I introduced,
    this PSU shows a high C/P ratio.

    The coming up review of mine is the most popular Elsa 8800GT 512MB VGA card.
    Then, I’ll use Corsair HX520W PSU again!!

    HX620W is the best PSU I've ever owned, and I've probably owned at least 15 of them over the years.

    For the money it cannot be beaten. Quiet, and cables are funky too.

    Yep, mine came off as well, put a bit of glue and problem solved.
    Also, although the cables look sleek I dont like em because they are too stiff :tongue:
    But performance wise you cant beat it :thumbup:

    Question would be, does the new VX and TX series live up to the standards set by the HX series.

    I think I've read somewhere the VX550 is no longer a seasonic, but the VX450 is. Not sure about the TX series

    I think you will find all the VX series Corsairs are assembled by CWT (Channel Well Technology).

    A good point to make here is that even though the HX series are assembled by Seasonic, they use Corsair specifications. They are not Seasonic PSUs.

    Yup another mad HX620 fan here! Love it!

    Re the 750W one, it's not modular. :( Looks to be a good one tho.

    Lol, that's the only problem I found with my HX520W :sick:

    I've seen a couple of reviews of the HX520/620 where the sticker is coming off as well.

    Maybe Corsair should have spent 5c more and got stickers with better glue :)

    Very happy with the PSU though...

    nothing compared to Tagans packaging, you get a suitcase and all for ya PSU :)

    wouldnt be too hard to expect a 700w+ one soon as the Seasonic M 12 comes in 700w :) seasonic obciosly have the core, corsair just have to re package it :)

    This PSU is great, I got a POS Hyper Type-R which was noisy and unstable and when I heard about this cheaper "seasonic" I snaffled it and have never looked back!
