Did you get a chance to measure the actual at-the-wall wattage at a particular ambient room temperature yet?
Does each of the four blades require two PCIe power inputs? The pictures seem to indicate that they are but I am not sure.
The air temp
in is 25.4 °C and
out is 43.2 °C, you will need the air flow of the fan to make it meaningful. there is some warm air feedback but i guess my ambient temp is around 25°C
I'm running the EVGA 1300 G2 PSU: just 1 PCIe power input per card, if you overclock with some secondary cooling you may need a second power input, it could be for a redundant backup.
I get 1120 +-10 Watts at the wall running 5 cards at 207Gh/s (1.25 tubes)
I get 1350 +-10 Watts at the wall running 6 cards at 207Gh/s (1.5 tubes)
the PSU AC input is 110V 15A so can overclock to the point where you pull 1650 Watts at the wall. (below 1400 Watts recommended per plug with standard wiring)
with the EVGA 1300 G2 you have to create a connection between these two before it powers on - It took me 6 hours to realize how to power on my system

Thank you for sharing your data.
It seems that the Tube draws at least 1W/GH/s at the wall compared to the S3 at 0.8W/GH/s (with a mere 80 Plus Bronze PSU) at 27C ambient.
Based on the pictures that have been posted in here, there's obviously a significant amount of cable clutter with the Tubes. I dunno. I feel that ASICMiner reverted to the exposed PCBs/components design instead of continuing on with an enclosed unit like they did with the Cubes; and I think Bitmain followed their lead and improved on the enclosed design by adding heatsinks on the other side of the blades and including two powerfull intake/exhaust fans with the S3, making it a truly safer, compact and modular standalone miner with less cable clutter.
I'm still mulling to get a Tube to play around with but due to the aforementioned points and the "pool" issues that I've been reading, I just can't allow myself to pull the trigger at the moment. To be fair, I can't allow myself to purchase more S3s either with the current pricing. So, I'm hodling.
