Topic: Bitmain S9 13.5 TH/s - 189 x BM-1387 chips ? (Read 146 times)

Hi All,

I was looking to buy the Bitmain Antminer S9 13.5 TH/s from an online company in the UK. They claim the unit is directly from Bitmain. The only difference on the specs on their site was the chips.

It is the same 13.5 TH/s units ?

Description from Bitmain Site:
AntMiner S9 Specifications:
1. Hash Rate: 13.5 TH/s ±5%
2. Power Consumption: 1323W ±10% (at the wall, with APW3++, 93% efficiency, 25C ambient temp)
3. Power Efficiency: 0.098 W/GH ±7%(at the wall, with APW3++, 93% efficiency, 25°C ambient temp)
4. Rated Voltage: 11.60 ~13.00V
5. ASIC Chip: 189 x BM1387
6. Dimensions: 350mm(L)*135mm(W)*158mm(H)
7. Cooling: 2x 12038 fans
8. Operating Temperature: 0 °C to 40 °C
9. Network Connection: Ethernet (network cable not included)
10. Default Frequency: 650M

The only real difference are the chips.
189 x BM-1387 and your unit shows 90 x BM1387

Anyone have any idea if this is the same unit ?

Please advise,
Thanks,
