Bitmain Antminer KS7 (40Th)

Arrived in the UK inside a week. Hashboard temps are even, all three boards inside 4°C of each other. Draws 3080 W at the wall, matches the plate. Machine arrived with the original manufacturer seals unbroken. Recommended if you know what you're doing with power planning.

Was on the fence for a few weeks before pulling the trigger. Haven't lost a single hashboard in the first month. Reading 40Th/s steady on the pool. Kaspa side, difficulty crept up in the two weeks after I plugged it in, still worth it. Sent it to the Georgia facility — power bills are a memory. Better experience than I've had with two other shops I won't name.

Was on the fence for a few weeks before pulling the trigger. Firmware update pushed on day one, worked without bricking anything. Bitmain's firmware isn't fancy, but it's reliable. Kaspa side, difficulty crept up in the two weeks after I plugged it in, still worth it. They didn't try to upsell hosting when I said I was running it at home. Sent it to the Georgia facility — power bills are a memory. Not a fault of the vendor, but the fan noise on this generation still isn't for indoor use. Not going anywhere else for the next one.

Two months in and no complaints. Network stability has been perfect, zero disconnects logged. Kaspa hashrate has grown so fast I'm glad I got in when I did. Zero drama, which in this space is high praise.

It's living in a colo rack, not at home. Pulling roughly the advertised wattage from the wall. Draws 3080 W at the wall, matches the plate. KAS pool ping is fine from central Europe, no orphaned blocks noticed. Return policy was refreshingly readable. The PSU cables are a hair short if you're rack-mounting. Would encourage a friend to buy from here.

My accountant will hate me but I'm glad I bought it. Power draw is consistent, no surprise spikes. Reading 40Th/s steady on the pool. The kHeavyHash side of the market is thinner than BTC — this one gets the job done. Home electricity would kill this, hosted power is the only way it works. Second time I've done business with Bull Miners, both smooth.

Arrived in the UK inside a week. Auto-tuned itself to the right frequency inside an hour. Kaspa side, difficulty crept up in the two weeks after I plugged it in, still worth it.

Bought two, keeping one, hosting the other. Coolant loop is holding pressure and the flow rate matches spec. Draws 3080 W at the wall, matches the plate. KAS pool ping is fine from central Europe, no orphaned blocks noticed. Packaging was serious — foam, straps, wooden edges on the pallet. Not a beginner box but a great value for the tier.

Delivery to Germany took eight days door to door. Runs quieter than I feared, no worse than a small vacuum. Draws 3080 W at the wall, matches the plate. Kaspa side, difficulty crept up in the two weeks after I plugged it in, still worth it. Sent it to the Georgia facility — power bills are a memory. For once, the product and the description matched exactly.

Delivery to Germany took eight days door to door. Efficiency is exactly where the spec sheet said it would be. The kHeavyHash side of the market is thinner than BTC — this one gets the job done. Five stars for what it is.
