I saw the first photo of the power plug. I get the end that plugs into the AVALON, but the other end that plugs into the wall is not what I use in my home - USA.

The attached picture is what I have at my home and that doesn't seem compatible with the power cord picture.

Mine came with a regular US power cord. The power cord pictured was not delivered to the US.

It's a regular ATX power supply. Any IEC power cable will work.

I owe my soul to the Bitcoin code...

That's a Chinese plug that comes with the unit. You will have to use a standard ATX power supply plug for your home.

Yeah, not everybody even know that exif data is so watermarking would be good thing to do.

Ok, now can you take those photos down until you watermark them?
Because I can guarantee if you leave them like they are they will end up on ebay on scam listings.

The community thanks you.

Thanks for point that out, I thought the exif in the image is enough to identify, but maybe not everyone is so careful

About that WiFi antenna.... can I connect by a normal ethernet cable without using WiFi ?

Yup, there's an RJ45 on the back. That's how mine is connected. I never even attached the antenna.

This is probably a dumb question but... I live in Canada, will I need a special transformer for the ASIC or it's okay to plug it in directly from my outlet?

If you have a power cable for PC, it should work. The PSU used in Avalon is actually a PC compatible PSU, draws 620W @ 120V-AC

Same with PSU, it is located near the end of the heatsink where hotest air is sucked into PSU

another cutout, rotate PSU by 180 degree

there are NO heatsinks near the PSU.

the PSU fan is not power enough to maintain a low temperature. the front fan will help the PSU to cool it self.

this is the last time i post about heat dissipation design, do what ever you want to do to your own machine and void your warranty please.

Second time I ask,

What are the warranty terms? Is there a warranty?

Thanks, I fully follow your advice Tongue

I added a 120MM FAN at the exhaust near PSU to draw out the hot air, now module temp is 28 degree at ambient temp of -2, intake Fans at 720 RPM
   [fan1] => 0
   [fan2] => 720
   [fan3] => 720
   [temp1] => -2
   [temp2] => -1
   [temp3] => 28
   [temp_max] => 102

But I don't understand why the temp_max has ever stayed at 102? Is it real or a bug mentioned in change log? Since it works, I have not updated firmware to the latest

A design change I might suggest for future revisions would be to also attach the module heatsinks to the top panel, and dissipate heat there too. This would also help to better physically anchor the hashing modules.

I realize that this would make opening the case more difficult.

Keeping the case closed will give overpressure inside the unit and pump out the hot air.

It will run the fans faster when the ambient temp is higher. I've not seen temp3 (exhaust?) over 50C even when temp1 (intake) was over 40C, but the fans run much faster to reduce the difference between the two.

I think the placement of WR703 is questionable: It is directly exposed under the hot air blowed from the heatsink, and 43 degree is not an ideal working temperature for such a small device without cooling. I have seen someone placed it outside of the box and that makes some sense

Same with PSU, it is located near the end of the heatsink where hotest air is sucked into PSU

Currently my unit is put on balcony and the temperature there is -2c degree, but my weather sensor still reports a 37 degree at exhaust

WR703 has an airflow so it's "cooled", even if temperature of the air is more than 40c.
PSU: probably the third fan gives enough air to it, module radiators are on the other side.
-2c => 37c Huh

strange. This means that inside at 25c ambient it will have 64c exhaust (improbable).

Thanks for the time you took to take the high quality photos, johnyj.

What is the PSU Huh

I've never seen a 12pin cable,8pin for mobo,8pin for PCIE sure,but not a 12pin.

Is it in lieu of a main 20 or 24pin mobo connector Huh

Its a standard ATX PSU going to a power routing board (pic #5). It looks like the 24pin and three 6+2 PCIe cables are used from the PSU to power everything.

Ok,I'm so duh sometimes Cheesy

It's 2 PCIE connected to a single adapter cable Roll Eyes
