Ronnie, CyberPower 600VA UPS is more than enough if you go with any 75w GPUs like Zotac GTX1050Ti 4GB.
Link for the UPS :Cyber Power Ups 600Va - Buy Cyber Power Ups 600Va Online at Low Price in India - Snapdeal
Local price listed for the above UPS is 2k
Link for the GPU : Buy Online | ZOTAC GTX 1050 Ti Mini 4GB Graphic Card ZT-P10510A-10L | Price in Indi
Local price listed for the above GPU is 12.3k
Zotac GTX1050 Ti 4GB Mini is sufficient.
Mini is a single fan version and so cannot be overclocked but OC version is dual fan version and can be slightly overclocked as it does not have any extra 6pin pcie power connector.
The OC / Dual fan version of Zotac GTX1050 Ti is priced around 13.7k in primeabgb.com
MSI or Asus has overclocked or gaming versions but priced well over 15k and so has 6 pin pcie power connectors.
Also, What are the components that you have purchased or ordered until now with prices, Please specify...
