    Excellent PSU

    Good design
    430 W
    Cables protected by mesh plastic sleeves
    Perfect SILENCE
    80 PLUS BRONZE Certificate (abt 85% power efficiency)
    Its a Seasonic - reliable.

    No modular cable.
    Its expensive.

    Prefer buying a mid tower/full tower cabinet that supports PSU bottom mount and with good cable management.Top mounting this PSU will make it heavier due to heavy cables. Buy a good cabinet of a reputed brand.
    Cable management will be a problem in small cabinets. So choose ...

    Its 1 x 12V not 2 x 12V

    Input 100 - 240V not 90 - 264V as flipkart saying (see the psu picture given, even in it it shows 100 -240VAC). Many other incorrect information here, for correct technical details visit seasonic site and look for S12II-Bronze.

    Seasonic S12II 620, 520, 430 all variants of same S12II-Bronze series.

    Its 1 x 12V not 2 x 12V, there is no special rail 1 or 2 for the division of amperes. +12Comb carries 30A.

    One of the best buy @ this price point

    Recently my PSU (cooler master) was not working and I decided to replace.After a lot of research,zeroed on Seasonic Brand. Now the verdict: I am happy after one week of use.The positives include very very fast delivery by Flipkart and beautiful online tracking. But packing done was absurd and hence one side of the PSU was deformed.The happy news was that the PSU was working well and is completely safe as internal parts was not damaged.

    Got the best price from Flipkart.

    Very silent

    Simply excellent!

    Simply excellent

    Fk delivered on the 4th day, which is good since the expected delivery was a full week later at the time.

    -Very silent
    -Stable voltages
    -Fully sleeved cables down to even the second and third connector.
    -80+ Bronze certified
    -5 years warranty
    -Has probably every connector you can think of (and never use LOL)
    -This specific model has been extensively tested by Hardware secrets so just reading the conclusion there is enough to buy this "flawless" PSU.

    -Too many c...

    fake image

    Ok. So i had ordered this product few days back after looking at the images i thought it a modular cable PSU, but actualy this is not a Modular cable psu this a normal sleve cable PSU plus the price they had kept for it is too high for the actual product, i think corsair vs 450 would be a much better product than this and at half of its price so plzz dont look at the picture and buy it as i did so i would recommend u to google the product and then go for it....coz this product is not worth of...

    Great PSU

    I burnt my previous Corsair VX450. Replaced it with this one, and it works like charm.
    I had installed a cheap 550W for a few months while I searched for a better one. That cheap one was from lolBall. Couldn't handle the system at all.

    The product is really good and properly priced. Delivery took some time but it wasn't from WS Retail. But Overall, I'm satisfied.
