Wow! Thanks so much for the advice! So what do I do? I'm looking at 5k watts with 10 GPUs total.
Measure your wattage pull from your socket w/ a kill-a-watt or similar device. Also, each card should use no more than 250-300w depending on your settings. Since you will have 2 systems up and running, you could just separate them onto different circuits in your house. Another option is to use a 220-240v socket, which is rated at much higher (will allow your PSU to run more efficiently too). For each 5gpu system, I'd estimate about <1500w draw at the wall when undervolted and underclocked. This depends on what type of card you get though, as some draw more power than others. You really should read up on basic electrical knowledge before attempting to plug in a 2-3000w heater into one socket. =) Once you start using a multiplicity of GPUs to mine, your power draw needs to be taken into consideration, and complexity of the operation will rise exponentially as well. This isn't as simple as 5x the GPU, 5x the profit. There are diminishing returns (however slight), and those need to be taken into consideration. Keep in mind that your power bill will skyrocket as well, and depending on your area's pricing, this could easily put you into the highest tier electricity bracket which is $0.30+ in some areas. ie - 3kw use, running 24/7 for a month is 72kwh/day, 2160kwh/month... multiplied by your cost per kwh. What some people do, when they're operating lots of rigs, is to get the power company to install a dedicated high voltage line in their house. Exactly. Most US NA circuit breakers are 20A. This will generally be per room. 20 amps at 110v is 2200 watts. Running dedicated GPU farms requires an electrician or at least the ability to wire and supply capacity from a breaker box. *disclaimer here.. felt it was needed. Thanks for the advice guys  As far as profit margin, I'm not doing it for monetary gain... although that's definitely a perk. The GPU specs have the watts listed as 500, so I'm going to buy 4 850w PSUs to handle the load. I've mined bitcoins before so not a true noob to the process (not a techie tho), but certainly the power requirements for these dang GPUs are scary to say to the least! I've already talked to the hubbie about the power requirements and he also suggested to connect it directly to the breaker box. We've already had it wired for our spa, so I'll check to see if that amp box (or whatever that switch thing is), can be used in some way. |

Hi RickJamesBTC,
You ever found that answer to the number of GPUs per system? Also, what are your thoughts about powering a 10 GPUs?

And Neptune's are available pre-order for less mula and it has hash rate of 3TH....

Lucky Cris,
Be sure not to draw too much power from your electrical sockets. A standard wall socket provides 1800 watts. 120 volts x 15 amps = 1800 watts
The sockets and the wiring are only rated to run at 80% of 1800w continually. 1800 watts x 80% = 1440 watts
Do not use over 1440 watts continually from your socket or you are risking an electrical fire. I'd recommend only using around 70% continually to give yourself some headroom. Purchase a Kill-A-Watt wall meter so you know how much power you're drawing from the socket. Do NOT you leave the kill-a-watt device plugged into the socket while your are mining for an extended time, because the kill-a-watt meters have been know to burn up (FIRE HAZARD) if large amounts of power are drawn through them continually.
Wow! Thanks so much for the advice! So what do I do? I'm looking at 5k watts with 10 GPUs total. |

So, are they trustworthy?
Anyone else that has already made a transaction and withrawed from there?
So far, so good, but I've only done small transactions with them. Another member did a 5k transaction, you can search the forum for his post. They allow fiat withdrawals to your bank account, but I haven't used that service yet. |

Okay, thanks for all your help guys |

So here's the site I'm using as a baseline: http://miningrig.a-r-d.me/I'm not getting the GPUs from Amazon, but I believe all the other pieces are in stock. Here's the plan: 2 AM3 5 socket motherboards unsure which extenders I'll need 2 cheapest AMD CPU 4 of the 850W PSUs 2 of the bare min memory. Will this set up work? I am sure of everything but the power, Configuration and capacity. There can be issues if you accidentally connect the +12v between the two separate power supplies. Either directly or through the card/mobo. I know that the pcie 6 pin connectors are isolated, I am not sure if you use powered risers, if that totally isolates the card +12v from the mobo +12v. Okay, now you're talking a different language, lol. I'm just reading directions, here. Do you suggest anything else aside from what's listed here? |
|
|

It is also my preference not to overload power supplies more than 60% of capacity. If you use them continuously above 60% the life span and efficiency take a dump.
repairguy, you're scaring me, lol. This is supposed to be fun! lol It is fun! I don't mean to scare you, 80% is probably ok for life but efficiency goes down. lol, I hear ya... and trust me, I'm heeding to the advice Did you see my post about the other pieces I plan to get... what do you think about those? |

Who has setup instant buy with coinbase and how long did it take? Does it work as easy as they make it seem. Is it compatible with Wells Fargo?
In the beginning it was just that - instant. But lately they've been cancelling people's order due to 'high risk.' |

I believe he was saying motherboard/ram/processor.
Hehe. Told you I'm no techie  |

With 10 gpus you would statistically find a block about every 20 days. You could just use pooled mining and eliminate alot of the risk.
Yes, I know. I want to first give it a shot solo. You neva kno! |
|
|
|
Ah! So I can build 2 separate computers with 5 GPUs each and still have the same probability of finding a block. That's if someone has found out how to point them at the same litecoin software. RickJamesBTC mentioned building a base system for under $200 each. I guess I must be going to the most expensive sites because for the PSUs alone (calculate I'll need 4), they're going to cost me 1 something each. Am I missing something? |
|
|
|
Just do two 5 gpu computers. You can build the base system for under $200 each. You won't have any issues, windows or linux.
But wouldn't this impact solo mining efforts? Aren't my chances of finding blocks greater with higher hash power? |
|
|
|
|
Damn it. Is that using Windows, tho? What about if I use linux? Can I beat that 8 driver limit?

I'm a little skeptical about coin.mx.. since they're only what.. 3-4 weeks old? and nobody but you on the forum has used em? Ehhhh
And btcquick's site came up on my internet security software as a malicious site related to online scams/fraud. No thanks. I think I stick with Coinbase until the price comes down. Only buying 1-2 coins then gonna trade anyway..
No, I'm not the only person to use Coin.mx... search the forum. Also btcQuick is a reputable company; they just never seem to keep in them stock lately. Oh, and please do keep us all informed when Coinbase cancels your order... it will happen |

8 GPUs for one mobo? The max I've read about is a 7 GPU config... how is 8 possible? Is that a special motherboard?
|
|
|
|
|
Yes, I want to solo mine, but I don't want two separate rigs. From what I've read, a mobo can only handle 7 GPUs at most. Forgive me, I'm not a techie.
