Charging over the Mrp and wrong warranty period

The product is good. Original MRP of this product is 4250.00 (inclusive of all taxes) and the warranty period is 3 years as shown on the box. Flipkart is charging 4188.57 + 209.43 as tax total of 4398.00, 148.00 more than the MRP and showing the warranty on the website is 5 years which is actually wrong and misleading. If u want to buy the product buy from somewhere else.

Amazing so far

I think most people have covered the stellar performance of this PSU in their reviews. I'd like to add a couple of points :

1.Before assembling my new PC I took a multi meter to the output of the Seasonic S12II 520. The amperage of 12v/5v/3.3v was within miliamps of what was claimed. And that is amazing. My experience with another popular competitor was disappointing.

2. There is hardly any noise from this PSU again comparing with the popular competitor this was superior in every respect...

Very Good Gaming Power Supply

Got this during the first week of June 2012 and going great since then.
Ample number of cables and a spare converter cable.
All cables are sturdy and are covered with glass fibre gauze sleeve to protect from damage from any fans/ hot spots.
A couple of cables needed for motherboard/ GPU connections may clutter with the GPU/ cabinet/ cPU fans. One can easily take care by straping.
The ATX cable, HDD, ODD cables can be managed very well.
I have connected 12V 24 pin (ATX), 8 pin, 4 pin to ...

Great PSU though slightly expensive

There are a lot of options in the price range that this PSU sells for. However, what drew me to this one was the 5 years warranty as well as the fact that it is the Original Equipment Manufacturer(OEM) that is selling the units unlike some other brands which are re-branding units from other OEMs. It is slightly more expensive but it gives good clean silent power and I am using this with the MSI Cyclone R6850 1GDDR5 PE/OC GPU with no problems at all.

* powering 560 ti OC and 5 HDD's with ease

Pros:
* Great Unit : A must buy
* Silent

Cons:
* You can see 5 years warranty but packing shows 3 Years.

Very good PSU

Seasonic has a good reputation and makes high quality PSUs
I am using this with a phenom ii x4 970 processor and gtx 550ti and it runs smoothly
Pros
40Amps on 12v rail
Silent
Made with highest quality parts

Cons
Cables are Stiff and hard to bend

P.S - If you are confused btw corsair cx500 and this then I would suggest you buy this PSU because corsair's CX and GX series PSUs are pretty generic and have a high chance to be dead on arrival(DOA) also this has 40amps compared to 34 of the corsai...

Internationally The best in 500-520 watt

THE BEST MODEL - many good features and good quality product.Input voltae and other protections are very good features whics are not available in local/simple psu.
It works fine in range of (90-250 watt) input power, which is good in fluctuating conditions and it is silent machine which works perfectly. I'm writing this review after 4 month of use and fid this psu very efficient. Don't ever go for cheap psu because some people thinks that psu only deliver power to other parts,it just do t...

Fantastic PSU

This is a fantastic PSU. I have a Corsair VS550 which theoritcally has 30W more output than this Seasonic model. But Seasonic outperforms without working too hard!

The Seasonic's interface connectors are just easy to plug-in and plug-out. With the VS550, I had to try hard to do the same. Both PSUs have similar braided wires and that is all very well.

The Seasonic boasts 2 PCIe connectors: 1 with 6-pin and another with 6+2-pin. The spec in Flipkart says only 1 PCIe 6-pin. This should be cor...

Best PSU in this price range

Using IBALL psus for years.I decided to buy this PSU for my Geforce GTX 650 ti Boost which requires 24A on +12v rail. This PSU provide 40A on +12v rail which is amazing. Quility of this product is best. You never go back to those cheap PSUs after using this. PSU is so silent for one moment you think it isn't working. Price is high but quallity does cost. So go for it you want disappoint.
