The Bitcoin network protocol was designed to be extremely flexible. It can be used to create timed transactions, escrow transactions, multi-signature transactions, etc. The current features of the client only hint at what will be possible in the future.

The Nitro version draws about 250W on games and around 325W on tests so I assume that XFX version will not be much different. I'm not sure what will be their load while mining Ethereum, but it should be somewhere between 80 and 100%. I believe that you need 2 power supplies just to be safe. 1 x 1000W gold rated and 1 x 750W gold rated.

Thank you for the advice. How would I go about connecting two PSU's to the same rig? I assume the 1000w would be used to supply power to the motherboard and 3 cards, and the 750w for the remaining 2 cards. Do I need any special power connectors for it?

i think you can do it with a single 1300w from evga, you just need to undervolt your 390 to -100mv so around 200w each at maximum, in this way you can avoid all the trouble with two psu, because i've read bad story about two psu and a h81 pro btc, when using double molex

I think they both require 1 x 6 pin and 1 x 8 pin connectors so you have to be sure that you can connect them all with the available cables from the PSU's. i think you can do it with a single 1300w from evga, you just need to undervolt your 390 to -100mv so around 200w each at maximum, in this way you can avoid all the trouble with two psu, because i've read bad story about two psu and a h81 pro btc, when using double molex
That's the better decision, but I'm not sure if he can do it...

Are you referring to the 1300w Gold rated one here? - http://www.newegg.com/Product/Product.aspx?Item=N82E16817438011My local vendor does not seem to have it in stock at the moment. Are there any other PSU recommendations I can look at? My local shops seem to have a few Corsair, EVGA and Coolermaster PSU's, but most of them show that I need to email them to confirm availability.

He meant that you will need 1300W gold rated PSU. It doesn't have to be EVGA, but it has to be from a good brand.

Ah, I follow now. What are some good recommendations for 1300w PSU's?
Alternatively, another option would be to use the above parts (H97; G1820 and the 1200w PSU) for 4 cards. I assume that at ~250w load, the 1200w EVGA would prove sufficient if I leave the cards at stock voltages, or am I wrong in my assumption?
And then, I can maybe try and get another setup with the same Motherboard and CPU, and add 2 cards to that build for a total of 6. My question then is whether a 750w PSU would be suffice for 2 cards in a similar build? Assuming a worst-case scenario of 275w power draw on each card and about 150w for the Mobo/CPU/RAM - which is about 700w total.
Thank you for your assistance so far as well, it is much appreciated.

Basically you need to have about 15-20% difference between the power consumtpion of your computer and the PSU specs (i.e. if your total power consumption is 800W, the PSU should be 1000W).
