Topic: Need Power Supply for Bitmain B3 (7 PCIe connectors and 328W) (Read 143 times)
Just to update people, I bought the 750W HP power supply from parallel miner, and they ended up shipping me two for the price of one which was kinda nice. So far it has been working well with the B3. The breakout board was very difficult to attach to the PSU though. I had to push so hard I thought it was going to break.
I suspect that we could run 2 B3s off of one APW3++ the same as with L3+s. (Or 1 B3 and 1 L3+). For a while they made a special version of the APW3++ with extra connectors specifically for setting up 2 L3+s on one, but they dropped that from production. However, it's only the connectors that are different so if you get a pack of cheap splitters it should work fine on a B3.
Thanks. The HP looks like what I want. I'm not trying to completely cheap out with a $20 PSU. I just figured a 1600W $200 one was a bit overkill.
I think that a good ATX psu is still going to cost about the same as the HP 750W, so why not buy a robust server psu with the same amount of money?
Even the noise level should be really quiet, since you would be running it with only half load capacity.
And also the power efficiency level would be good.

I ordered a Bitmain B3 miner, and I'm trying to find a suitable PSU for it. Unlike other Bitmain miners, it only requires 328W to run, so I'm looking to get a smaller and cheaper PSU than the APW3++. However, I need find a PSU that has a least 7 6 pin PCIe connectors. Is there such a thing on the market? All of the smaller PSUs I can find don't have enough connectors.
Do they really require all 7 PCIe connections though?
I know that with some of their Antminers you need every connection because it would shift the current and they would start melting but since you are using only 328W then no more then 4 should be necessary.
The Antminer S3 had 2 boards and each had 2 connections but most of us just used 1 PCIe per hash board and it ran fine.
It used around the same amount of Watts as this B3.

The bottom line is that you should not go too cheap with the power supply.
You want to have a robust one.
