I planned to set up a mining rig which would allow me to play a game or two with almost all the eye candy one. I do test rigs and advice friends basis the component availability. I have focus on efficiency rather than just the statistics. I had planned to setup a R9 280x based rig but had to settle for a 270x as 280x was not available in India at that time.
The data is pertaining to India and alot better prices will be available abroad.
Following is the component selection list.
Motherboard: Asus M5A78L-M-USB3 32GB DDR3 AMD Motherboard – Rs 4600
Processor: AMD FX-Series FX 6300 6-Core Processor (FD6300WMHKBOX) – Rs 7995
RAM: Corsair 4GB (1 x 4GB) DDR3 1600MHz Desktop Memory (CMZ4GX3M1A1600C9) – Rs 3250
Power supply: Corsair VS Series VS650 650W High Performance Power Supply (CP-9020051-WW) – Rs 4350
Hard disk: Western Digital Caviar Blue 500GB SATA – Rs 3740
GPU: Asus Radeon R9 270X 2GB DDR5 – Rs 17580
Cabinet: Doesn’t matter (I bought Circle CC830) – Rs 4500
Total- Rs 46015
Would have been Rs 56000 with a R9 280x.
One can opt for a cheaper processor for AM3 socket which would reduce the cost further. I wanted to game as well so didn’t want that to be a bottleneck.
The above can decently mine at 410+Khash/s at less than 70 degrees. The cabinet has 5 fans for the airflow.
I would recommend to buy a motherboard with at least 2 PCIE 16x slots so as to have room for upgrade if you wish to add another card for mining.
I had to order another Gigabyte motherboard which can support 2 full slot cards and another 2 on ix slots via riser cable.
I would also recommend a beefier power supply just in case you don’t want to run on two separate PSUs.
