Re: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH
this WILL void warranty as per BMT. if possible i would connect all 3 pcie to each hashboard.
Alcheminer-like scrypt miners are equipped with only one PCI-E power connector at each hashing board. The boards run more or less OK with ~300 Wt per board. From this point of view 2 PCI-E connectors for each S7's hashing board should be more than enough.
Sure the more connectors are plugged the better S7 will work.
i am NOT going to re-phrase it AGAIN & AGAIN.
even 1 pcie will work
but again LAST time ! from BMT themselves :
There are 3 PCI-e connectors for +12V DC input on each hashing board and all 3 are required.
of course it is up to each owners choice & risk as :
A 90-day warranty is provided starting from the shipping date.
just saying, there MUST be a reason why there are 3 & NOT 2 or 1, if they can make lesser & lower the cost etc why didn't they make it ?
Other miners are other miners, this is S7 itself.
I may sound harsh or rude, but it is for each & everyone's sake.
miner breaksdown *hopefully* not then starts crying, waiting, complaining, sendig defective pasrts to bmt, etc . . . by that time, TOO LATE to say uh-oh
