Review of the Bitmain Antminer S15 28TH/s

So, Bitmain is all about creating high-speed, low-energy custom chips. They’ve been at it since 2013, launching their first bitcoin miner, the Antminer S1, that same year. Fast forward five years, and they’ve rolled out a bunch of models in the Antminer series like S1, S2, S3, S4, and the big names S5, S7, S9. The latest on the block are the S15 and T15, which hit the market on November 8, 2018. The Antminer S15 is packed with a new 7nm chip process. Official reviews say it's durable and energy efficient, boasting features like "high performance, longer-lasting, and more power-saving". If we look at the specs, it’s got standard and low-power mining modes. In standard mode, you're looking at a power ratio of 57J/T, and in low-power mode, it hits an impressive 50J/T. This really sets a new benchmark for bitcoin miners out there. The specs for the Antminer S15 are out, and just recently it was sent to Cybtc for some testing. Stay tuned for our independent review coming up!

Nice info and thanks for original link.

Only wattage is specified because by themselves the Amps pulled or voltage in are meaningless. Only using the 2 together giving you wattage matters. A miner ran with a high line voltage will pull less amps than a miner ran on a lower voltage line. Yes, they could spec the min/max amps together with the min/max line voltage but considering it is very simple math to figure out makes it rather pointless.

Line voltage is variable no matter where you are, it even changes based on load so there is no reliable way to give a specific amperage rating. e.g. 1500w @ 208v = 7.2a 1500w @ 240v = 6.3a

This range of 6.3 amps to 7.2 amps is pretty much the correct range. I think the psu can run a little lower volts then 208 so off the top of my head my s15 does 1565 watts at 220 volts = 1565/220 or  7.113 amps Now I went on line and they mention 200 volts as the lowest volts I can find. So 1565/200 = 7.825 amps may be max amps And 6.3 may be min amps

Directly giving folks an Answer like that ^^ does not encourage them to learn and think for themselves.... I gave the 'why' and stand by my answer as OP knows how to do the math so let them do it themselves based on what their line voltage is..

true  but sometimes a young child wants to hold an adults hand to cross the street. I would go into a long story about that, but it is not important for me to tell it to you. Only that you know a little kid once put his hand out for me to walk him across the street. So I went at my answer from that angle.  Not anything wrong from your method just different angle for you than me.

We may need to start a "phil"-osophical thread. I like both approaches. The only thing to consider is fact checking if handed answers and mathematics in school isn't what it once was either. That given my 30A 240v amp lines wont touch a s15/t15 until the psu is rated for higher. As it's not worth the risk for my very small set up to short myself on any warranty at all.
