Used mining hardware you can actually trust
Bobbie Hash Matrix started with a simple frustration: buying used ASIC miners online meant trusting a photo and hoping for the best. No way to know if the hashboards actually worked, no real numbers, no one to call if something showed up dead on arrival.
So we built the thing we wished existed. Every miner that comes through our Portland, Oregon warehouse gets racked, powered on, and run under load before it's ever listed for sale. What you see on the page is what that specific unit actually did on our bench, not a reprint of the factory spec sheet.
How we actually test every unit
This is the part most resellers skip. Every miner is connected, powered up, and run under real load so we can record its actual hashrate, power draw, and efficiency. We check hashboards for faults, confirm fans are running clean, and inspect for any physical wear before it's graded.
If a unit doesn't perform the way it should, it doesn't get listed. Simple as that. The numbers on our product pages come from this bench, not a factory data sheet from years ago.
Packed right, shipped fast
Once a unit passes testing, it's packed in anti-static foam inside a reinforced outer box built to handle freight, whether it's heading across town or across an ocean. Orders ship within 1 to 2 business days, free, nationwide and worldwide.
And if something's still not right when it arrives, you've got a 90-day return window and a 6-month warranty behind every unit. We'd rather make it right than have you stuck with hardware that doesn't work.
