corsair power supply tx 550m is a good power supply for running ENTRY graphic cards like RADEON 7770 HD , NOT LIKE mine msi radeon r9 270x , THIS CARD IS POWER HUNGRY SO PURCHASE A HIGH VOLTAGE POWER SUPPLY TO RUN IT PROPERLY also flipkart service was very good , since i received the product 5 days before the actual delivery date mentioned on website . the psu is running as well as it could.

I LIKE TO MENTION THAT THIS POWER SUPPLY SAYS 550 IN ITS NAME BUT THAT DOES NOT MEAN IT IS A 550 ...

The price for TX650M is almost the same as this one on flipkart (Rs. 7000).
Go for that one instead. Or if you dont need modular then just the TX650 (Rs. 6000) if you're going to SLI. I use TX650 myself with GTX680 SLI.

If you're going to use a single gpu, there is no need to go for anything higher than TX550.
On local store this TX550M is priced at only Rs. 5800.

3 stars here - for the high price.
