What 7.5-8.0 TH/s looks like.
Dissipating ~24,000 BTU.
Most PSU's = EVGA 1300's, powers 3 S3's each with current to spare.
Bitmain Rocks!

Awesome work planet, when I saw the red cables I thought that looks familiar as I am using the same EVGA 1300 to power 3 S3's each (they fit perfectly 3 per shelf in my 42U cabinet vented to the attic

), I only have 7 units and just checked the power at the wall all 7 use almost exactly 2400watts combined.

Thanks, we'll be adding more in the near future. But not until the power company runs in another 400A@240V.

@ stock freq, feed by the EVGA 1300's I measure exactly 325W each.
Each "rack" (purchased @ Menards ~$50) has 12 S3's.
So power consumption of a single rack ends up being 3900W.
The equation to convert watts to BTU is: watts * 3.15 = BTU
So each rack is dissipating 12,285 BTU.

2x racks = 24,570 BTU

So your 7 are dissipating 7,560 BTU or about what 2 Walmart space heaters would do.
If you live in a place that has cold winters (like us in Minnesota) vent that heat in to your house and get paid to heat the house.

Regarding the power discussion, as you can see in the picture only 4 of the S3's are using 4 Pcie connectors (Cuz' they were there I used'em).
All but one of the S3's are clocked @ 237.5 and running just fine.

I live North of you in central Canada. It will be cold enough here in a few months. I just wanted the other new people to understand that these things really are micro heaters. So far my basement is holding fine as AC always did keep the basement a little to cold anyways. 4200 watts of heat makes a huge difference.
