I was thinking I might be just better buying coins in the exchange just like you would with stocks and not paying fees like electricity and mining rig, although mining rig is fun but it is dangerous for newbie to setup and run. As soon as the power bill is over $100, which I am sure i will hit that in a week or so, I am contacting Solar City. They do a no money down lease, finance and cash buy out.

He has a 800mh/s farm at his home but he stopped 9 months ago. He said, "Back in March & April (before the A/C really started being run regularly) my usage was (6604 kWh & 7029 kWh).  With A/C usage over the summer I peaked out around 7800 - 8100 kWh.  But, I'm all done now.  I stopped about 2+ weeks ago.  It's nice to have the house quiet and cool again.   I had a flat rate contract that expired, so I had the option of readjusting my flat rate (upwards) or simply reverting back to the standard "pay for what you use" billing.  In either case it was going to be higher.  The new adjust flat rate would have still kept it pretty profitable.  But even then, it just felt like it was getting close to the point of diminishing returns.  For example, when I started mining in Aug/Sept of 2015, I was mining 6-9 blocks/day (as much as 45+ ETH/day).  When I stopped 2-3 weeks ago, I was down to ~3.8 ETH/day and falling.  For that little amount, the heat, noise, and hassle were making it borderline worth it, especially after 1 full year of it already."

with that riser, would you use something like this https://www.moddiy.com/products/6%252dPin-PSU-Modular-Power-Cable-to-PCI%252dE-%2830cm%29.html to avoid Sata connector?

Hmm. There is no way for me to avoid using Sata connector?

My risers take female molex adapters. Yes i want to swap to 6 pin to molex, like this: http://www.ebay.com/itm/252733245120?ul_noapp=true however, i need the white end is female molex adapter to connect to my risers.

Here is another one. I need to make sure it is female molex.

I live in the 2nd or the highest electricity cost in the county-SoCAL. It's not profitable for me. I pay more into electricity than what I will make each month. hmm.

wow it went from 3 months 15 months of payback in few weeks? I could at least mine other currency. I am planning to download nicehash.

Hi.

I have 5 EVGA GPUS. 6th is on the way.
3 GPUs: EVGA GeForce GTX 1070 08G-P4-6178-KR and take only one 8 pin power connector.
2 GPUs: EVGA GeForce GTX 1070 08G-P4-6278-KR and take two 8 pin power connectors.
2 PS: 1 Seasonic X series Gold 760W and 1 EVGA Gold Series 750G2
1 motherboard: Asrock H81 Pro BTC
1 cpu: Celeron G1840
2 rams: 4 gb ram each.
1 SSD harddrive

6 PCIE risers http://www.ebay.com/itm/10X-USB3-0-1x-to-16x-Extender-Riser-Card-Adapter-SATA-Power-Cable-PCI-E-Express/132221021363?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

These risers come with these SATA to molex connectors:

Questions:
1.   I am really worried about fire from SATA to Molex connectors. SATA is not designed to withstand a lot of power. I am trying to avoid all SATA by connecting to all PCIE risers directly to PSUs via Molex.

Here are my 2 PSUs:



The EVGA comes with one set of 6 pin to 4 molex connector cable.


The Seasonic comes with one set of 6 pin to molex connector cable.

The Seasonic comes with at least 4 sets of 6 pins to SATA connector cable.


I am trying to keep one GPU per 6-pin to Molex cable and 3 GPUs per PSU.

I don’t have enough 6-pin to Molex cables. I have called EVGA twice, and they agreed to send me 3 6-pin to molex cables for free. It really depends on CSR you talk to. First CSR told me no. Second CSR said yes.  On EVGA PSU, you can interchange between connecting either SATA and Peripheral ports with either SATA or Peripheral cables. This is really cool. So EVGA PSU is not a problem.  

On Seasonic PSU, their tech support is not open 24 hours so I couldn't get hold them today. I will need about 3 6-pin to molex cables. How will I mod the existing 6-pins to SATA connector cables or can I buy them off ebay? I would think it is as easy as going to Seasonic website to buy the extra cables, no, it's not there.

Here is a picture of side by side pin. The molex to 6-pin cable is on the left and sata to 6-pin cable is on the right.


If I were to mod the existing 6-pins to SATA to 6-pin to molex, do I need to pay attention to the difference in the pin connection? The difference is SATA to 6-pin has one more pin on the top left.


2. In the future, what PCIE riser should I get? As far as i know, molex connectors are safe. It's the molded SATAs that are not. My existing PCIE risers are molex. There are some risers that are 6 pins, however, if I get those, I would need to get 6 pin to 6 pin cables to PSU? Can I find those cables on Ebay? Will they work on EVGA and Seasonic PSU?

3. One lesson learned from this time is some PSU requires 2 8-pins. Really.

Luckily I have enough ports in Season PSU so this is not an issue.

4. On my motherboard, i have connected the main motherboard power supply. I will need to connect power to CPU. Is there any other element I will need to connect? This AsRock mother has at least 4 power connections via molex, Sata, etc.


5. My next step once I have all cable issue resolved, is to  update motherboard BIOS, disable the on-board GPU. Reduce the power usage on GPUs by tweaking clock settings.

6. After that, I will need to download mining software and open wallet account and start mining. Anything else I am missing?

7. On the 2nd rig, if I am motivated to do so and have enough money, would be to rinse and repeat, and make sure PCIE and PSU have enough right kind of cables and connectors.

Thanks.
