3L is a lot. where are you based? make sure that your electrical setup can take the load coz that much money will add 2-3kW to your load (very rough estimate)

Anyways, the main component you should focus on is the GPU. While the 7990 is the fastest in terms f hash rate/card, it is too expensive and as a result not the best in terms of Rs./khash.

For 3L, you can build 3 rigs (unless you can get your hands on some powered risers) - Config:

GPU: R9 280x ~23-25k (gives you about ~700 kh/s) 2-3 on each rig
MB: Gigabye UD3 ~9,500
CPU: AMD Sempron 145 ~1,800
RAM: 2GB Kingston/Corsair ~2,200
PSU: Seasonic/Corsair/CoolerMaster
        650w ~3.5-4,000 - will barely take 2 280x's (i wouldnt risk it)
        850w ~9-11,000 - will take 2 280x's
        1000w ~ 12.5-14,000 - will take 3 280x's

For the PSU, you can choose to go with multiple 650w's on each rig in order to reduce cost. Use a 2PSU cable.

corsair GS800 - 800W power supply only about Rs. 7,500  ,

With that budget you can purchase 7 x 290. (non x version) . Price is around 34000 per 290. If you purchase 8 units you can bargain and reduce the price.
7 x 34000= 238000 Rupees.
with the  remaining money you can purchase other parts.

@archit this is very good info here...i myself use exactly these component PSU is 850 watts with 2 r9 280x (one of them is sapphire toxic)
i measured the power the rig uses only 620 watts on full load..room for one more r9 270x

Hi,

I am looking to build a mining rig, my budget is at max 3,00,000

well if you like it  you can  get one from Highkart, they have the miner on a DIY, they send you the parts and you build it your self.

Hi,

This is specific to Scrypt based coins, Try to get your hands on 7990 graphics cards, they are expensive, but give you a hash rate of atleast 1.1 to 1.4 MH/s per card. (much easier to handle heating issue with less no. of cards per rig)

Or from a value point of view, go for Asus r9 280x cards (700 odd KH/s per card), as they are cooler and easy to handle with the GPU tweak software.

Try to get your hands on riser cable of this kind          - https://bitcointalksearch.org/topic/sold-out-flexible-usb-based-powered-pci-e-risers-18-20each-370907
Try this link, will help you get an idea about diff rigs     - https://bitcointalksearch.org/topic/--7216

Hope the above details are helpful  Grin
