i clouldn't arrange alternate psu for testing so i have decided to buy new one , is following psu will work fine ?
Corsair CMPSU-430CXV2UK 430 Watts PSU | Psu | Flipkart.com
This SMPS is great considering your RIG specifications, go for it and I am glad you found it on flipkart. Pricing is good and shipping is free so overall great buy.
I hope you are 100% sure that you do not want to adding anything else to your RIG in the coming months, years; in the light of that the Seasonic S12II 520W is a better buy.
Pricing is on the higher side [for the Seasonic unit], try to source it locally [where do you stay?].
You can get the Seasonic SMPS from this deal thread on TE as well.
Hope this helps, Cheerio!!
