I spent $US5000 for miner S21 and $US555.00 for this power distribution ANTPDU PW12V1 that the Bitmain customer support recommended. It turns out this power cord distribution is not the right one for my miner S21 made by Bitmain.I keep emailing to Bitmain requesting return and refund, but they deny. I do not understand why they do that since this purchase is from Bitmain recommendation. I believe this China Bitmain company does not live up the international business standard. I JUST NEED THE REFUND SINCE I CAN NOT USE THIS POWER CORD DISTRIBUTION.
