DHL delivered today and had them hashing in 10 minutes, thanks to the setup guide's that have been provided Doge and the other guy.

Right? I thought with the SPI connections it would be finnicky but this is hands down the fastest miner I've ever set up.

Just chained my 3rd AM-V1 together! ALL 3 running off a single 1000 Watt PSU too!

Thanks for the sweet equipment BTC Garden.

Anyone know if the older boards can be retrofitted with the PCI-E headers? That would make my day! hehe

You may want to change 1 unit over to a different power supply.  PSU really don't like being very close to their maximum power output.

I agree - that's cutting it close. I have 2 running off a 750 and I even think that's cutting it close. (It's not, 720W rated continuous 12v output PSU is only drawing 699 from the wall including RPI)

Also worth noting - I swapped out the fans with nice 140mm silent case fans. (Thanks for the advice bobsag et. al.) Not only is the damn thing completely silent now, I cut power consumption by 20w (across 2 units, 4 boards).

methinks The installed JSY fans seem to be power hogs.

Those JSY fans are rated at .45A, the installed fans rated at .3, a difference of .15a
.15*4=.6A total savings
.6*12v=7.2W theoretical savings. Where'd the other 12.8 watts come from? Maybe - maybe I brought the PSU into a higher efficiency area of it's output curve but I bet those fans are hogs. I'll hook one up to a bench tomorrow and see what it really draws. YMMV.

[mstrongbow]

Yeah I know it's cutting it close but that's how I roll at times. These PSU's have been pretty solid for me and I keep them fairly cool. Plus the cord is cool as well, which means a grip!

I'll toss my kill-a-watt meter on it later and get some readings posted.

Based off a kill-a-watt I'm pulling 650w from the wall with two miners with a corsair AX860i platinum rated

Nice, so theoretically 3x AM-V1 miners should pull 975 watts according to your readings.
Thanks!

Strongbow: Well, you'd have to use a different power supply because the AX860i is an 860 watt affair.

The larger PSU in that line is the AX1200i and according to their website it should get about 90% efficiency at the 80% load you'd be putting on it.

The AX860i is rated at 92% efficiency at 650w. So roughly, the 3 miners on the larger psu would be 2% less efficient, so theoretically you could be pulling 20 more watts.

Ninja: out of curiosity, is that power supply also running the RPI?

The numbers also won't increase by exactly 150% because your'e not duplicating the Pi's load as well, but that's only about 5w, so we can subtract 2.5 from the added load. I'd guess in that case 992 watts at the wall for 3 on an AX1200i. 1.066w/GH including controller. Not bad.


Better than the 1.14w/GH I'm getting with 2 and a pi on a bronze 750w supply. The AX series would save me $10 a month in power but probably not worth the cost considering this bronze rosewill I got for $50, and the AX series costs minimum $200. 15 months for the price of the PSU to amortize and I doubt these miners will stay profitable for even 12.

Most PSU's will out-survive mining gear so the investment is well worth it as the PSU will power your next-gen gear as well. I know I will be replacing miners before replacing PSU's, not counting any RMA's of course but how many miners have you RMA'd over the years?

If you're planning on quitting mining after your current miners have lived their life in your hands, then not purchasing a PSU that can save you $10/mo then I would have to agree.

I recommend the Dell 750W server supplies for these. 1 Supply powers 4 total boards, at just about 80% load. Cheap, reliable and also even cheap to replace. We are using ~50 of them for our units right now along with several clients.

Nice pricing too! Save me one of those Tees you have listed on MinerSource if you would please 
I would like to snag one of those when I pickup one of these Dell PSU/boards so I can design a safety enclosure for the boards, maybe some stacking clips for the PSU's as well.

Jonny: the RPI is just plugged Into the wall but its running 4 miners

[jdany]

It's only been 24 hours since I put my new AM-V1's online, but I am very impressed with their build, ease of setup and consistency.

I was a GPU miner for the longest time;  So, I was expecting some hectic setup and tweaking.

Literally, 15 minutes to be hashing at the advertised rate - and has stayed consistent since.

I'll be buying another 4 very soon.

[Chris_Sabian]

I'm running 1 miner with Corsair RM850 Gold and pi using the 120V to USB adapter.

Solid 341 W at 310.1 +/- 2 Gh/s

1.1 Gh / W

Set-up was extremely easy.  A small issue editing the cgminer config file manually but tech support answered my email question in about 10 hours.

For anyone in AUS, we have these also at http://btcminer.com.au/product/dell-750-watt-server-supply-breakout-board/
Currently running my AM-v1's also.

Can you add New Zealand to your shipping list on btcgarden.com?   Tried sending a mail on the site (failed with unspecified error) and tried the link out to to that Chinese postal company, site is a mess and doesnt load.


Also, FWIW, the price on (what I assume is an official disti) http://btcminer.com.au/product/btcgarden-am-v1/   is way way higher than on BTCgarden, what gives?

Website btcgarden.com supports calculating shipping cost for NZL now.

Any quotes for Wholesale/Batch/Reseller Buys?

Any quotes for Wholesale/Batch/Reseller Buys?

I was told purchases over 10TH may see small discounts of around 5%

hoping these guys can keep ahead of bitmain pricing (they have to since they use 50% more power), I ordered a pair of units yesterday and am looking forwards to building a farm with btcgarden equipment if the price and qaulity are good
