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.

You may want to PM the maintainer of the cgminer software ckovalis he had/has a 4x 7970 rig running so should be able to tell you the power needs also seen mention he was thinking of selling it off, he is fellow aussie so you may be able to work out deal with him and save some cash.
