Re: Liquid Cooled Miner C1 Discussion and Support Thread

Is Corsair RM850 80+ Gold PSU enough for running one Antminer C1?

Yes, although I still prefer the 1000 as an investment if you're buying a new one.

I can confirm the rm1000 is great with theses. I had a cold ambient temps and PSU was in its "quiet" mode.

I have got conformation I am being sent 2 pumps as replacement's. I bought a molex to fan connector so I don't have to worry about my wire frying boards.

All said it looks like I am losing around 2 weeks mining on 2 C1 machines. Down 2 board fan controller's on 2 separate boards. Lost higher priced coolant. Paranoid and bought 2 extra pumps, and molex to fan boards. With extra parts I ordered I am hoping to lose only around a week, but it came at a premium.

I will know more when I get all the parts from RMA.

I highly suggest 2 things after all of this so you don't lose mining time.

Order a extra pump (I went to ebay to get from closer location)
Order a molex to fan power board (example http://www.amazon.com/Phobya-4-Pin-3-Pin-Splitter-Connection/dp/B007S3T4O0/ref=sr_1_3?ie=UTF8&qid=1415897694&sr=8-3&keywords=molex+to+fan this is just 3 pin, the pumps they use are 4 pin, but they run off two through harness

i really like that molex to fan power board.
those would work great in my pc builds.
this is part reasons why i always read these threads.

It's working great with it. And no chance of fried boards like with sysgear harness (version 1).

One thing to mention is I replaced pump with a 3 pin fan so I was able to do a molex to fan pin board with all 3 pins. If you are using the syscooling pump you for optimum power need one 4 pin for their pump. They do make some with a mix so it's possible to get one that does this.

Why would you change the 4pin connection to a 3? There is a reason why it is a 4 pin. The most obvious is for some kind of control. That 4th pin controls the speed and I'm guessing if it senses a higher temp runs the pump a little quicker. Unless there is no logic in the circuitry of the pump at all. It actually would have been easier for syscooling to keep everything 3pin, but I think the 4pin is there for a reason.
That's why you can't find any molex power boards with 4 pin connectors on them.

Well I choose one that shipped close on ebay. It actually runs faster the original pump.

Original pump harness does not use 4 they cut off the side of plastic to rig it..... so you didn't get 4 with it.

And yes... you can find molex with 4 pin. http://www.frozencpu.com/products/25650/ele-1333/Phobya_PWM_8x_4-Pin_Splitter_81136.html#blank

Do you own a C1?

I paid for 2 C1's. Just waiting for them to get shipped to me. I'm in the US. Already have the power supply and extra coolant. I've used the Corsair RM1000 on my KNC and it is a flawless power supply. I'll be using that power supply. If there is no electrical issue of using the supplied harness then I'll just use it. I assume it just plugs into one of the plugs on the top of the C1. This is my first antminer, so I don't know much about them or where power connections are, etc....I actually see 4 PCI-E connectors on the C1, but only 2 are needed to power it I guess? And I'm surprised you found that 4pin block. I searched that site and couldn't find it! You must have better search capabilities then me. I'm just getting impatient, because I want to be up and running ASAP.
