12× GPU frame + PSU kit

Ordered 120 S21 XP on a Tuesday, they were on a plane on the Friday and hashing eleven days later. The batch report arrived before we paid the balance, which is the part nobody else does.

Four units arrived with a board out. Reported it on day three with photos against the serials, replacements shipped the following week. No argument about whose fault it was.

They talked us out of hydro. We had 1.4 MW and one electrician, and the honest answer cost them a bigger invoice. Two years on the air hall is still running and I know why.

The tier pricing is real. We split an order across two quarters and the second batch came in at the 200+ band exactly as the offer said it would.

First import for us, and the paperwork was the part I was dreading. They spoke to our broker before the cargo left and it cleared Tashkent in two days.

We buy spares from them now even when we buy machines elsewhere. Two PSUs per hundred units on the shelf, and the fan kits turn up before the bearings go.

They sized the loop, not just the machines. The dry cooler spec came back with our design day in it, which is the first time a supplier has asked me what the summer actually looks like here.

Firmware was pre-set to our pool and the worker naming matched what we asked for. Saved a day of laptop work across 90 machines.

Twelve machines. Small order, and we were still treated like the file mattered. That is why the second order was ninety.

The used batch came with provenance — where it ran, what cooling, what firmware. Every other seller I asked answered that question with silence.

Payback figures they gave us matched what the fleet actually did within about six per cent, and the gap was our downtime, not their arithmetic.

We asked for a split shipment — air for the first sixty so we could commission, sea for the rest. They booked it that way without arguing that it was easier the other way.

Every serial in the test report traced to a pallet position. When we found a weak board in month two, the claim took one email.

Settlement in CNY through their agent chain worked exactly as the offer described. For us that was the whole reason to place the order.

What I value is that the price on the offer is the price on the invoice. Three suppliers before them found a reason for it to move between the two.
