Title: [WTS] ASICMiner Prisma 1TH @ 1000 Watts, taking offers....
Post by: bigredbutton on November 30, 2014, 12:11:11 PM
I bought an ASICMiner Prisma from Canary's group buy several weeks ago and finally decided to admit defeat. I can't seem to figure this one out.

I have a unit that hashes around 1000-1050GH poolside @ 950-1100 Watts. The unit did at one time hash at 1450GH @ 1250Watts. This only lasted for two days though. Perhaps some pro-miner can restore the unit to its full glory..?.


Unit comes as-is.

Escrow? Yes.

US shipping only.


I am currently entertaining offers.

I will offer 0.8.

On a side note, have you checked the firmware to make sure all the chips are hashing as expected?

hrm. I'll consider your offer. Might need a bit more for shipping though.

Not sure how to check if the chips are hashing on cgAM Minera image.

Is this a full unit with controller & power supply?

if so I will offer .85 & cover shipping.  Escrow by trusted forum member.

edit:  No worries about the power supply, just wanted to confirm.  I should mention that my offer expires at midnight tonight (Eastern time).

Yes it is a full unit with 4 boards.

No PSU they're a dime a dozen. I find the resell value pretty bad and I can still get use out of it.

But if the price is right I'll throw in a RPI with cgAM .img, if someone needs it.

Where can you get a good 1000 watt power supply for .10 cents?

you can get a decent server one for less than $20 without much effort. 

if I can get mine working - I'll send you an offer.  I think my place right now is too cold for it to work

Where in the world is it profiable? In Germany 1kWh costs 0,27 Euro and for mining I get only 2,90 Euro a day. That makes a loss of 3,58 Euro a day.

In the US its about 10 cents per kWH. Why are you even mining in Germany with such expensive electricity?
