Heads Up About Antminer T21 They're 3-Phase!

I just ordered some Antminer T21 190T and found out they’re 3-phase. Really didn’t see that coming there was no mention of it on the Bitmain website when I ordered. This is gonna make things super complicated for me.

I feel you. I got three too one is here, two are on their way. There’s an adapter available but it’s pricey.

Wait, really? Are there options for that adapter?

Check these out. One might work for single, could run one or two of them. But yeah, expensive. Gotta find a way to handle the 3-phase situation.

Ugh, Bitmain is really dropping the ball here. Wish there were more brands to consider.

There are alternatives like Canaan and Whatsminer from MicroBt. They’re typically more reliable, too.

I see that... leaning towards Whatsminer myself. They look more reliable and take up less space.

I've got six Whatsminers, two M30s and four M50s. Solid gear, no complaints.

Yeah, once the M50s kick in, they run smoothly for months. Just wish they didn’t take forever to boot up.

Totally agree, Whatsminers are top-notch.

For real, I've sold 24 M31s+, only had one with a dead PSU in four years. No other issues at all. My Antminers? None last over 2.5 years.

Lucky you with the Whatsminers. I have to rewire everything now since my farms are all 3-phase. This complicates my entire setup.

Sounds rough. I feel like I messed up big time with this.

You’re not alone. Bitmain naming it T21 is confusing. They've never had a 3-phase air-cooled miner before. It should've been called T21-3 to make it clear. Can't you return them?

I heard you could convert them to single-phase with the right PSU.

There’s a video on converting T21 to single phase. Might not be too bad if you can sell the unused 3-phase PSUs later.

That video might actually help. Just reached out to Altairtech for advice.

Let me know how that goes. Heard the T21 with standard PSU can hit some serious performance.

Altairtech confirmed those parts I asked about are right. Ordering now!

Awesome! Keep us updated.
