Byron Stuart –
Fans are loud at full speed but that’s expected at 3645W. Performance is exactly what Bitmain advertised, no throttling issues.
Tristian Gallegos –
AMP had it in stock when a few other sites were showing pre order only. Arrived well packaged with PSU included.
Morgan Jimenez –
Upgraded from an S19 XP and the jump in efficiency is noticeable on my power bill already. Solid unit overall.
Davis Warren –
Setup was straightforward, plugged in and was hashing within the hour. Express shipping from Asic MarketPlace got it to me in 3 days.
Rhys Richardson –
Second bitmain unit I’ve bought through AMP both times support was quick to respond when I had firmware questions.
Michael Cox –
Been running this for about a month straight now, zero downtime and temps stay manageable even with three fans working hard. Genuinely impressed with how stable the hashrate has stayed.
Ollie Jackson –
Bit of a learning curve getting the firmware dialed in right, but once it was set up properly this thing has been a beast. AMP’s team answered a couple of my setup questions same day which helped a lot.
Harley Barnes –
Went with Asic MarketPlace after comparing prices across a few sites and glad I did, the HELLO100 discount plus express shipping made it an easy choice. Unit showed up in perfect condition and has been mining nonstop since.
Liam Martin –
Power draw is no joke at 3645W so make sure your circuit can handle it, learned that the hard way with a tripped breaker at first. Once I moved it to its own circuit, it’s been flawless.
Alexzander Kelly –
Honestly wasn’t sure about buying a miner this expensive online but Asic MarketPlace made the whole process easy, from checkout to tracking updates. Hashrate has held steady right around 270Th since I plugged it in.
Tobias Blair –
Noise is real, this lives in my garage not my house, but the numbers speak for themselves. AMP shipped it fast and it was fully assembled, just needed power and internet to get going.
Leroy Higgins –
Did a lot of research before pulling the trigger on this one and Asic MarketPlace kept coming up as reliable, glad I trusted the reviews. Unit arrived exactly as described, hashrate hasn’t dipped once.
Tatum Goodwin –
This is a serious machine, not for a spare bedroom setup unless you don’t mind the fan noise. That said, the ROI math checks out fast at these efficiency numbers. AMP’s checkout with the HELLO100 code made it an easy decision.
Cruz Dunlap –
Third miner I’ve bought this year and by far the smoothest experience, from AMP’s stock availability to how fast it shipped. Been mining around the clock with no hiccups so far.
