^^Its your wish then.. I know about Hipro, have used it... Though it is better than intex stuff, still it isnt in same league of Gigabyte 460W (FSP 400W OEM)..
So, if i were you, i wouldnt mind spending 2k on a Good PSU to safebound a 6k GPU and a few HDDs...
Hence my 2 cents:
1. Get a Gigabyte 460W - Rs. 1.7k/1.9k after selling your Hipro
2. Get a Palit 9800GT - Rs. 5.6k from theitwares.com (mumbai)
Total = 7.3k something = Much Better than 4770 on a uncertain and old 300W psu
Else if budget no tension then:
1. Get a Corsair CX400 - Rs. 2.8k something after sellling hipro
2. Get a Palit 9800GT
here you can upgrade to HD4870 later after upgrading to a 22" or 24" monitor.
