Showcasing my friend's New Bitcoin mining rig

[5W-KILO]

At first I felt hurt that he didn't let me know even though I helped him with his ETH rigs in the past, but after a while his excuse did make up for his decision. Or maybe not to others?

My friend choose to buy this device for Bitcoin mining because it looks more like a GPU, the excuses he gave me was that he has too many parts laying around from his old ETH mining rigs, he has
Working motherboards and expensive PSUs, even risers laying around.

I took a trip down to his place and I was amused, this device works in a plug and play style. I helped him set things up and it works in an instant.



Do you think that already having few PSUs and risers around that you can buy these GPU style miner rather than the normal Asic miners we are used to? I went on to use my own gadget for measuring power consumption and it shows that the device is taking roughly 177watt from the wall while the device promotes 150watts.



I guess that's extra power consumption from the PSU part? Do you think it's a good excuse to say that because you have PSU and riser you can go for this BG02 miner rather than other brands?

What do you think?

If it is quiet it could be a space heater.

Also if he had 2 of them and a good efficient psu I think he could do better than 24.5 watts.

What did it cost?

I would buy 1 or 2 if they were not costly.


Psu units are tricky.

They have sweet spots for being efficient.

A 750 watt psu platinum is most efficient at about 400 watts or two of these miners.

So if he has a 750watt gold and is doing 150watt pull from the miner it will not be that efficient.

Last I looked at these units they were costly.

The miner is very quiet, I was surprised and impressed.

He paid a supplier in China for $210.

The PSU I choose was a 850watt Platinum, he bought almost all those PSUs specifically for efficiency because he was rocking 1660s on ETH using solar panels before, I specifically advised low power consumption graphics cards at the time.

Of all the six PSUs there is only one Gold PSU, that's why I said he has expensive PSUs.

That's pretty cheap for 7th/s compared to NerdQAxe++, which is around $300+ for 4.8th/s.
This Magicminer BG02 seems to looks like a GPU but doesn't need a PCIe connection and can also be connected wirelessly.

How does your friend turn the PSU on? are your friends use a jumper wire to connect the green wire and ground to keep the miner on?
