[Group Buy] Avalon ASIC Batch 3 [CLOSED- Seven 4 module Avalons ordered]

[Miner99er]

US Breaker Box

95A ((20X4)+15) * 110v = 10.450KW

7 * 650w = 4550w or 4.55KW  so basically half his available wattage...if nothing else was run off that service.

I was just trying to point out some possible problems that might come up. I wish everyone the best of luck with this endeavor.

He's running them on 220v  

No...he WILL hoping he can run them on 220v..it really depends on what powersupply you have...

Just be aware...I posted in this thread because I saw what I felt where some legit questions that had not been addressed by the OP.

MOST powersupplies are 110v/220v auto switching. There's even a little 110v/220v switch on the ones that aren't.

Another thing, the PSU's are bought in China. China is 220v. Why would they throw in a 110v only PSU? These are shipping world wide. There's no logical reason to throw something like than in.

REGARDLESS, Do the math. Most homes in the United States are wired for 220V service, with either 120, 150, or 200A mains. Power is simply NOT an issue. I'm all for throwing a line conditioner if the group thinks it would be wise, but other than that, let him keep them in his house. No need to co-locate something already co-located. /Queue Xzibit.

That's how this forum is.  In the Market Speculation subforum everybody is a fund manager, in the services subforum everybody is a professional, and here everybody knows all about electronics

[Miner99er]

I'm not a certified electrician.

Not even close.

But I have asked Certified Electricians how this works, and I try to pick their brain simply cause I'm curious.

It's pretty simple.

Amps * Volts = Watts * 0.8 for overhead.


Edit: But yeah, ask me to run conduit lines, proper pipe radius bends, what the difference between 5 different types of 110v outlets, etc, etc... I couldn't tell you. Least, not right now.

I actually went to school for this and these guys are schooling me. lmao

Yes, there are still units for purchase. I decided I did not want to take on any more investors, as it was starting to get a little out of control.

It would be nearly impossible to keep track of all the transactions if I ordered one/two/several more. I already have my work cut out for me as it is.

Let me know if you need/want any help trying to automate things. It wouldn't take me long to put all the donations and payment addresses in a database and help automate the dividend payments. At the very least, we could generate a script to run on a bitcoin qt client or something. A properly configured linux VPS should be able to automate most of the payouts. We could also put all the info on a .com somewhere so investors can check their earnings based on that week/month's mining coins.

Just my $0.02.

This sounds practical and sensible to me.

Very good idea. Though I hope you mean 0.000225479 BTC?

he had the ability to order without PSU, which they actually recommend to avoid any problems in customs.  so hopefully he did that option and will just purchase 7 high-end PSUs to install himself.

REGARDLESS


As stated before....use whats between your ears. Have you looked into 220v power supplies?  Have you looked into the different connectors between 110v and 220v? Sure you can plug your stove or washing machine into a 220v receptacle....most computers(i.e. power supplies)? Not so much. You want to argue and defend this post..fine..I have no problem with what the OP is doing....I was just pointing out that there might be something that was overlooked that could end up being a problem.

Actually most modern ATX power supplies are autoswitching, and can take anywhere from 90V to 250V or so.

I just plugged my GPU miner with it's regular Antec PSU right into my outlet that I had wired up for 240V and turned it on.  No magic smoke came out, just hashes.

If in doubt, the label on the side of the power supply will indicate acceptable input voltage(s).

This is also kinda what I was pointing out. You want to jury rig your 70k investment with improper wiring that's fine. i.e. wiring a 110v receptacle's for 220v.....BRILLIANT!

/done with trying to be nice to idiots with their heads up their asses.

[skyhigh2004]

Why is anybody still arguing about power issues or constraints?  He already uses 5000 watts of gpu-miners and the asics will draw less power and in turn generate less heat.  There's really no need to bash people and tell them to use their brains when if you do use your common sense you'll known his wiring is more than adequate for the asics.

Edit: totally forgot that the asics will have the fourth module therefore will use a little more juice than his gpu-miners.  Still way more than adequate.

Let me clear up some misinformation about power issues that others have said ITT. Some people have hit the nail on the head, but some have been pretty far off as well.

First of all, the standard US home uses 120v and 240v, not 220v like some others have suggested.

People are correct in saying you can only use 80% of the amps of a circuit safely running at 24/7 continuous load.

I will be running this equipment on a 30a 240v circuit and a 60a 240v circuit.

Amps x Volts = Watts, So... [(30 x 240) + (60 x 240)] * .8 = 17280w

I could run 17280 watts of Avalons safely from the 240v circuits I have ready to go.

I only expect the Avalon's we purchased to used about 5600w of power (800w x 7).

Therefore, I already have the power infrastructure to run many more than 7 Avalons as is. People are making this out to be a bigger deal than it really is.

excellent...also i hope the cny psu are good for your supply

I went to school for this stuff. Coinhoarders math is spot on. Even if it wasn't the worst that would happen is that the breaker cuircut would blow and he would have to move some of the units to another cuircut. If he was going to run with the asics/money he wouldn't be dealing with these issues on this thread. It seems this is all legit. People need to relax. I'm sure some issues will come up and it was already said that we could all vote on solutions.

A more likely issue is delayed delivery. I'm willing to bet we will not get all the units at once. It was already stated that all shareholders will share on all asics so it may happen that only one is delivered and we are all sharing those payments while the rest of the asics are delivered.

If you are an investor the best thing you can do to keep your investment safe is to make coinhoarders job the easiest possible.

[skyhigh2004]

Completely agree.

Hello everyone. I just wanted to introduce myself. I'm excited to be a part of the group. I got 8 BTC in the mix!

Does that equate to roughly a 1/103 (8btc/824btc)? Just checking to see if I have roughly the right numbers. Also, with 8 4mod units we have 640,000 mh? or 640/gh.  I enjoy a little trading and collecting. Thanks for any help out there.

My dad started as a lineman, and worked up the chain to become an EE and design transmission lines.
I actually did work as an electrician's helper for a year.  Plugging & Switching, they called it.  Had pretty fast dykes and Kleins.

Hi, I've been working on the numbers all night and am maybe about 1/2 through confirming investors deposits, payout addresses, and forum names. I took a break to check the forums and.. umm... crunch some more numbers.

A crude estimate of your monthly portion of the profits can be calculated by using the following formula:

(X-409.08) * .98 * .97 * (Y/715.694) = Your portion of profit in USD

Note: Enter X in USD and Y in BTC
X= Net profit (without power costs/pool fee/my fee)
409.08 = Power costs I expect to be about $409.08/month
.98 = pools 2% fee (may be a little more or less depending on what pool we choose)
.97 = my 3% fee
Y= your investment in BTC
715.694 = total amount invested in BTC (this number is not exact, but very close)

With the above formula, use any Bitcoin mining calculator with these numbers: 595,000 Mh @ 5600 watts.

I hope my above math is correct, someone please check me. I have been dealing with numbers with many decimal places for hours now.. at my day job aswell..
