      Why is there a shipping charge for this item?

      Sellers with Flipkart Assured waive off the delivery charge for Orders over Rs 500. For Orders under Rs 500, a nominal delivery charge is added per item.

      Sellers without Flipkart Assured may or may not add a delivery charge to your Order. This is subject to Seller discretion.

      What is the estimated delivery time?

      Sellers generally procure and ship the items within the time specified on the product page. Business days exclude public holidays and Sundays.

      Estimated delivery time depends on the following factors:

      • The Seller offering the product
      • Product's availability with the Seller
      • The destination to which you want the order shipped to and the Seller's location

      Why does the delivery date not correspond to the delivery timeline of X-Y business days?

      It is possible that the Seller or our courier partners observe a holiday between the day you placed your order and the date of delivery, which is based on the timelines shown on the product page. In this case, we add a day to the estimated date. Some courier partners and Sellers do not work on Sundays and this is factored in to the delivery dates.

      What do the different tags like 'In Stock', 'Available' mean?

      'In Stock'

      Products‘In Stock’ are readily available with seller.

      'Available'

      Products listed as ‘In Stock’ are readily available with seller.

      'Preorder' or 'Forthcoming'

      The product is not released yet. You can however ‘book’ an order for this. Shipping happens only after the product launch.

      'Out of Stock'

      Currently, the item is not available for sale. Use the 'Notify Me' feature to know once it is available for purchase.

      'Imported'

      Sometimes, items have to be sourced by Sellers from outside India. These items are mentioned as 'Imported' on the product page and can take at least 10 days or more to be delivered to you.

      'Back In Stock Soon'

      The item is popular and is sold out. You can however 'book' an order for the product and it will be shipped according to the timelines mentioned by the Seller.

      'Temporarily Unavailable'

      The product is currently out of stock and is not available for purchase. The product could to be in stock soon. Use the 'Notify Me' feature to know when it is available for purchase.

      'Permanently Discontinued'

      This product is no longer available because it is obsolete and/or its production has been discontinued.

      'Out of Print'

      This product is not available because it is no longer published and has been permanently discontinued.

      Why does the estimated delivery time vary for each seller?

      Delivery times are influenced by product availability, geographic location of the Seller, your shipping destination and the courier partner's time-to-deliver to your location.

      Please enter your default pin code on the product page to know more accurate delivery times on the product page itself.

      Seller does not/cannot ship to my area. Why?

      Enter your pincode on the product page to know whether the product can be delivered to your location.

      If you haven't provided your pincode until the checkout stage, the pincode in your last used shipping address will be used to check for serviceability.

      Whether your location can be serviced or not depends on:

      • Whether the Seller actually ships to your location
      • Legal restrictions, if any, in shipping particular products to your location
      • The availability of reliable courier partners in your location

      At times Sellers prefer not to ship to certain locations. This is entirely at their discretion.

    Value For Money, Ideal for Indian conditions

    I guess I was the first one to buy this from flipkart. hehe. Bought it just 2 days after Cooler Master launched the Thunder series in India. (and it was in-stock at flipkart within 48hrs!)
    Been using it since one week, and hasn't found any cons yet.

    This is absolutely a value for money PSU (better than Corsair vs450) and I have a few points to justify that:
    1. 450w at 85% efficiency
    2. Operating voltage 180 to 260w (specially made for Indian conditions)
    3. Low on Noise (surprisingly stays qu...

    Solid Performance without any fancy LED gimmicks

    Dont expect this SMPS to throw a lot of blue LED lights around. This is totally LED-less. But the connectors, cables, braids are top notch. Never faced any issues installing this work-horse. This can be installed in tall cabinets too. Wires are really lengthy and you wont need any extenders.

    Performance wise, never faced any issues. The volts appear to be solid and my system never showed any issues. Has one big fan, that sucks the inside air, and blows on the circuit. The hot air then gets p...

    WARNING: UK/European Socket Plug not Indian Plug.

    WARNING: UK/European Socket Plug not Indian.

    So you will need to use an adapter. Or use a different power cable. Real pity, since the included power cable is fuse protected and otherwise solidly built!

    Disappointed

    Starts making a noise after about an hour of use if mounted on the top of cabinet. perhaps it behaves better if it is in bottom mount cabinets (as the fan direction will change to top).

    But, expected better from Cooler Master. A new PS making an irritating sound after some 45-50 minutes of usage is surely not acceptable, especially from an expensive brand like cooler master.

    Other than this, the PS worked as expected.

    Silent POWER

    It is one of the entry level PSU series from Cooler Master. Its a great PSU for its price, very silent and cool. Before getting this I was using an iBall PSU (cheap one) which caused random reboots after nearly 3 months of usage. While selecting a PSU, if you go for cheap brands then you may end up with a fried motherboard someday. Its wiser to do some research and spend some money on a branded PSU like the ones from Corsair, CM, Antec, Seasonic, etc. This one has got long cables and the cabl...

    A very silent SMPS

    This is a very good power supply for PCs. Though I have connected only one HDD and an optical drive along with one chasis fan to my PC, the power supply works without much heating up. In future I would be adding one more HDD to the PC and I feel that the PS would be able to take it coolly. Since my use does not include overclocking or gaming I have nothing to report negative about the PSU during the past one month's use.

    Loved it

    I am writing this review after 2 years of usage.
    The product is very very silent and yes it works flawless even after 2 years with all the dust around it.Its powerful enough to cool down the temperature even if the dust particles sticks to it.
    You must go for it.
