That's why there is the internet or am I missing something?

some people don't have internet access

But he obviously has. May I ask you where you live?

I don't understand what you are asking.
I would not hesitate to use a multi rail power supply, so long as I knew what I was doing and knew I could evenly load all 12V rails. Why would you buy a mono rail power supply at an extra cost if it's not needed? I can't really tell you what would be a good deal in your area, though. Your market is much different than mine, unfortunately.
There seems to be some internet rumor going around that you can't use more than one power supply on one rig, but that couldn't be further from the truth. The servers bringing you the text you are reading now, they have multiple redundant power supplies and they do alright. I run lots of 6 gpu rigs, and I generally use split power supplies. I generally size one 100-200 watts larger than the other one, just for the cpu/mobo overhead.
Since you already have some power supplies, I would suggest getting a power meter like a kill-o-watt so you can figure out exactly what your gpus need for power. Then you can buy power supplies sized perfectly to your needs. I had the lucky advantage of using a power supply that would read off pre and post 12v conversion power draws though, you will need to do some simple math to figure what the gpu itself uses.

Hey Thanks for your feedback!
What i am asking is this:
How can I power my 12 gpus using the 2 psu i already have, and any combination of those PSU i have listed above? that are the only psu available to me atm.

Prices are in ARS that are only for comparison between the psu and for comparing single to dual psu prices, say 1x 1kw platinum costs AR$3299 and 2x 750w erp750-sp cost AR$2538, meaning 1kw for AR$3299 and 1.5kw for cheaper AR$2538.
