Hi,

I'm building a Bitcoin miner and plan to add 3 more graphics cards once I get it up and running. So that's 4 x 7970 GHz Edition cards and I don't think the 1000W PSU I picked out is going to be enough. What say you?

$482.00 Gigabyte Radeon HD 7970 – 3GB GDDR5 – (1100MHz, 6000MHz) Ghz Edition GV-R797TO-3GD
$339.00 Intel Core i7 3770K Quad Core CPU
$312.00 Antec 1000W HCP Platinum Series PSU
$207.00 ASUS P8Z77-V Mainboard
$163.00 Fractal Design Define R4 USB3.0 Mid Tower Case Titanium
$107.00 Corsair 16GB (2x8GB) DDR3 1600MHz CL10 LP Vengeance Unbuffered
$84.00 Intel 330s/60GB/SATA3/R 500MBs,W 450MBs/25nm/3.5"Kit

Total $1,694.00 (plus 3 x $482.00 Radeon HD 7970 in future). No current plans to over clock, but might do I future. My alternative was to put a Corsair 1200W AX-1200i $395... Better to be safe??

Note: Prices are in Australian $.

Kind regards,
QG
P.S: I know I might be a little late with the GPU mining, but I'm not doing this for the money. More for fun and research. Might use the PC for a gaming PC after a year or two.
