Hi Guys,

I have a package waiting in customs right now that I'm patiently waiting for. In order to complete the build, I have to order a couple more parts. Here is the current build:

Current Build:
1 x ASROCK H81 PRO BTC
1 x INTEL G1821 CPU
1 x 8GB RAM
6 x GIGABYTE R9 280X
6 x USB POWERED RISERS

So, I still need to order my power supplies. I was thinking of going with these guys:

1 x 1000w EVGA SUPERNOVA G2
1 x 1300w EVGA SUPERNOVA G2

Question 1:
Would this be overkill in terms of wattage? Perhaps I can save $50 and go with two 1000w? And how should I connect everything up.. 4 cards on one psu and the system + 2 cards on the other?

Question 2:
I've heard of people linking power supplies together so they get turned on at the same time, how do I do this and is this necessary? What do they mean by "do not mix" when doing this.

Question 3:
I have 6 USB powered risers.. some of the posts I've read from people make me nervous about this whole power concept. But my plan now is to connect the two molex on the motherboard up, as well as connect all six powered risers to each card. I guess I'm concerned about frying the motherboard or the cards. Hopefully someone can give me some advice here on the plan.

I think that's all the questions I have for now.. thank you all.

Hello ima get this mobo and cpu too.However I will buy 2gb goodram ddr3 9/9/9/24 (cheapest ddr3 I found)and i wont use a case hard drive etc.Also i will underclock all except gpu for max power save.Make sure these psu have been reviewed properly and do more research.

Q1) there is no info on internet (at least i couldnt find any) on exactly how much power do cards use when scrypt mining. There is only that one radeon uses 50 W more bitmining than gaming. I will just measure power usage with one card and two to find out better.

Q2 Paperclip is best option I think. You ll keep pc on so you wont care about that paperclip anyway.

Q3 Im not sure about the risers theoreticlly they wont be used unless needed but you dont want anything to burn. If anything would go wrong then you have warranty anyway
