Makes sense is it is reasonably powerful unit (for off the shelf stock) and it is self cointained which makes bulk assembly easier.   Still I do hope HF makes "naked boards" available.   The H80i isn't exactly cheap at $80.  Even if HF is getting an unbranded version for coolit for say $60 each there are three and that is a significant cost point to the total sytstem cost.  I guesstimate the case at $60.  If the power supply is 2x 660W they are $150 ea (if larger it will be even more).  Toss in two intake fans at lets say $10 ea.   So the balance of system cost in a Sierra the non-ASIC costs is are something like $600 (60 x 3 + $60 + $150 x 2 + $10 x2 = $560, round up to $600 for reduced labor and packaging).  Sierra's current pricing w/o MPP is $6,300 so knock $600 off and it would be ~$5,700 for 3 naked modules or $1,900 ea (maybe $1,500 ea in bulk)?   Sell them as naked modules and let the community come up with innovative solutions.

Those coolers look like the Corsair ones made by CoolIT.



I guess Cointerra is using the same system as Hashfast?

I like the idea of Dual PSU, especially for expansion and failover

Well failover implies each PSU can handle the full load and that isn't confirmed.   Expansion is improbable given the dimensions of the chassis.   To their credit HF used the available space pretty well.  I don't see you putting another module plus fan/radiator/pump combo in there without extensive redesign.  Might be an interesting project.

They may not include 2 large enough PSUs, but it looks like you could upgrade the PSUs to be big enough. Its hard to tell without hard numbers, or MPP/non-mpp

Yeah it does seem confusing.   I can't see any reason for the second power supply.

One new thing is notice the usb port above the left power supply.  It looks like it connects to one of the boards.  So single usb port to board #1 and the boards 2 & 3 daisy chained off it.

As for a 4th module you could certainly mount a board but where are you going to put the watercooling radiator?



HF is the same water cooling radiator used for BabyJet with obviously only 1 used (2 if upgrade module is installed)?

i was looking at the specs of the 2 psu's last Monday and the combined wattage greatly exceeded that needed for 3 modules which i calculated somewhere around 1400W.  while briefly cruising around the Seasonic website i noted that i didn't see any single platinum 80 plus psu above this, am i wrong?

I would certainly hope the Sierra doesn't require 1400W DC.  That would be ~1500W AC and would make the efficiency worse than 1.2 J/GH.  Given that 55nm Bitfury does less than 0.9 J/GH at the wall and KNC does less than 1.1 J/GH I would be hoping for something more.

The stated efficiency of BabyJet is 350W at the wall or 0.88 J/GH.  Assume a 90% efficienct PSU that would mean 350W AC is 315W DC.  Three times that is ~950W DC.   Seems that either a single 1000W Platinum or 1250W Gold PSU should be fine.

For the record, at the high end SeaSonic only has 860W & 1000W PSU Platinum models and 860W, 1000W, and 1250W Gold models.

One edit:
one thing I hadn't considered is that HF may be saving cost by using a single model PSU across products.   Say the BabyJet comes with 660W PSU.  Rather than stock a different model the Sierra comes with 2x 660W PSUs.  Note the above is just my theorizing.




i meant at the wall OC'd.  i might not have the #'s quite right.

What kind payment Hashfast take or Bitpay only?

Thank you.


They also accept bank wires.

Dual power supply sounds familiar. Now where did I see that? Oh, yeah...

Redundant power supplies?  That would require 2 PCI-E power inputs per hashing module?  Or is that just for power load balancing?  Kind of over kill unless the new 4U chassis can accommodate more than 3 Hashing units?  Am I dreaming or does it looks like there is room for at least another hashing module on top of the lonely one to the right?  Wink

Misleading blog post title! However, Seasonic is awesome.

Totally, I was like upping the power consumption or hashing power then blam total let down...

HashFast tells me they're going to e-mail later tonight about the support position for the forum here, if I get employed I'll forward you guys details as soon as I know them.

The chips are pinned all they have to do is plug them into motherboards already installed in cases and ship them out.

They are not.  Given the relatively short lifecycle of miners and the lack of need for upgrade chips designing a socketed package is just additional for no benefit.

Then again with automated fabrication it is more than possible for an assembly house to place/solder/test thousands of boards a day.

We plan to receive the chips during the week of October 20th.  Exact date depends on variable physical processes at TSMC.

In other words, expect delays. 2 more weeks(tm)? Say it ain't so HF...

Where did you read this?

Nowhere, because it is false.
The chips are not socketed.  They [will be] BGA, each mounted on its own board (similar to KNC devices, though each board will contain a USB interface).
