Avalon A1041 Review

[minefarmbuy]

Most consumers hate "surprises" cart. Though this one is pretty reasonable for US buyers.

so is the a1047 the same as the a1041?

Does the a1047 also have low power mode?

Mostly the same and yes. Only difference I see on the one I got Monday is that the PSU is attached like the 1041 was *supposed* to use. (all 3 of my 1041's have the loose PSU) Speeds are >31THs in Normal mode and >36THs in High Performance

edit: Oh, and the A1047 uses a C19 plug for power - not a C13. It comes with a cord but the wall end is a 'crow foot' style.

[coffeefan]

How fat cables are you guys using to feed it? Seems hard to get powerful C13 for reasonable price (as well the connector itself is rated for 16A max. I think).

I use www.stayonline.com for all my cables

[wndsnb]

Yes, these are running 36-37 TH/s @2098 give or take a bit depending on ambient temp...

Has anyone else verified these numbers on the latest batches? 56W/th vs 64W/th in high power mode is a pretty giant difference.

Well I just finished a few tests with the A1047 I rcvd on Monday:

Date: Oct. 1, 2019
Miner: Canaan Avalon 1047
Rcvd: Sept. 30, 2019
Power source: Triplite 6kva dual-conversion UPS
Voltage out: 230V +/- 0.5%
Ambient temp: 85F (29.4C)
Note: UPS is also powering a M10 pulling 2.17-2.18kw, this baseline load is subtracted from UPS readings to give test miner load.

- Miner in Normal mode for 30 min -
Power: 2.06kw
GUI speed: 31.31THs
Efficiency: 65.79W/THs
After 24hrs speed/power are the same.

Date: Oct. 2, 2019
- Miner in High Performance mode for 1.5hrs -
Power: 2.65kw
GUI speed: 37.6 THs
Efficiency: 70.48W/THs

Do note that the miner is running in a fairly warm room and that definitely affects power usage.

[philipma1957]

yeah  if you can get them in a 10c or 50f room  they get a good  efficiency boost.

even 16c or 60f helps

Over 28c or 80f they start  pulling more  power.

A lot of other companies have the same issue.

[Katun]

Where can I purchase a type I to type B adapter for the power supply on this miner (A1047.

try blokforge.

[HagssFIN]

Where can I purchase a type I to type B adapter for the power supply on this miner (A1047).

Why not just buy a C19 to Type B power cord?

[Katun]

I did not think to replace the provided power cord. This seems like the better route to take. Thank you for the suggestion.

[digital$]

recently on a order for A1047's was told they didn't have LOA certification required by some(dunno?)countries.  out of interest, anyone have any issues ordering state side without that certificate?  Im in South Africa just interested if requirements in US are the same and if they have since obtained that certificate(my understanding is they were waiting for it)

[philipma1957]

I got got my a1041 from haggsfin  and it does not work.  It is the Same  style unit as tested in this review ,  but has the loose psu.

I seem to have bad psu it is putting out 0 volts to the boards.

I will post log

I know those 0's are wrong and the psu puts out 0 volts

I  not sure what is wrong as my connections look good.

Dead as a door nail for the moment. Not sure what to reset or clear to get psu to turn on.

[PassThePopcorn]

Is it hooked up properly? I think it's a primary over  current for the psu error. Possibly just a bad psu.

[philipma1957]

I have to go up to Clifton I have the two others up there.
I think this was dropped in shipping.
Hagss sent me pictures of it befor he shipped it and the psu box had no dents. When it arrived the psu box had a dent. My guess is the two pieces were dropped from a six to ten foot height and something in the psu broke.

When hagss shipped the m20s this summer it went missing for two weeks arrived with a dent in the cardboard box which cracked a fan. I repaired that.

[HagssFIN]

It seems to be somewhat unsafe if Finnish postal service Posti + the USPS combination is used for the shipping.. :/

[philipma1957]

When I get to Clifton I will shut down the working Avalon disconnect the power on the psu.

Fire 🔥 up the good gear with just the controller attached to the good psu.

I want to see if the good psu does the same readings when not attached to the hash boards.

Or if it gives out power.

I will then see if the good psu will run the dead 💀 unit.

At hagss it appears that the gear gets handled very hard at the airport.

Since both boxes sent one in July one in Oct had damage.

I asked Steve of Avalon if he has a way to rma the gear.

I sent him an email this morning.

[minefarmbuy]

Will be kind if they do considering how the damage occurred. Seems likely that heavy boxes were stored high in a parcel truck.

[philipma1957]

I think they toss the gear around offloading the plane.

Steve replied to an email and said he would forward this to the rma department.

Maybe I will get a replacement unit. I will post back on it.

Planning to bring unit to Clifton hopefully on thurs  will test to see exactly what broke.

Psu or hash boards or both.  Once I determine what is broken I will follow up here and with avalon to see what replacement parts are needed.

Best case is psu is dead hashboard are good.

Second best is psu works hashboards are dead.

Worst case is both psu and hashboard is dead.

fans work
controller works
