How does this look? $1200 for 3 pieces which mmines 440gh/s which means 1.3th/s.

Sounds right? Is this a good idea for a beginner miner?

What about asking this question in the dedicated thread: https://bitcointalk.org/index.php?topic=671189.0

Creating a new thread for this is simply useless.

sorry new here!

You won't get much joy there, the people are committed to their miners.

you can move your own thread, think it's under options bottom left,either to beginners and help or to mining speculation.

https://bitcoinwisdom.com/bitcoin/calculator calculators abound and each will give a different answer.

looks like you get 'free' power. this will make a huge difference. be absolutely sure your dorm room has no fair use policy. and is safe. what if your miners get stolen?

you also need a big old power supply to run three of these, adding to your outlay. might be better to get 2 miners and a smaller ps. that thread would help with this, and other S3 threads.

there is always some debate when your question gets asked. why must you mine? you might not even break even, and you might be better off just buying coins now while they are cheap.

it is miles more important to learn about wallet security, business and politics than mining.

You can use a small computer like a raspberry pi to power your asic miners and maybe save on your bill.

Kind of irrelevant since OP is asking about S3s.

Currently the S3 is the best deal going.  If you pick up three, you'll need either a single PSU to drive all of them, or individual PSUs - one for each miner.  I use an EVGA 1300 G2 to power 3 units at a time.  That PSU can be had for about $150 on Amazon (after rebate).  I highly recommend it.

Now, please note that the 3 miners will draw about 1000W from the wall.  You need to factor that into your costs, unless of course you don't pay for electricity.  I see a mention of you going to college in a previous reply.  Make sure you understand the school's fair and acceptable usage policy for power.  Also, if you're going to have roommates, you might want to consider how they will react to 3 miners constantly running.  If you're going to school in a cold climate, they might be overjoyed at having 3 little space heaters in the dorm come winter time.  Of course, if you're headed to where it's warm...
