And since I have seen where the discussion is going, this is Room 3, actually by time, it was Room 1 - my first bitcoin project - for those who like more cards on one motherboard, and custom built solutions. My 5970s and 6950s - only problem is they pull too much power.

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin-Qt, which will follow the rules of the network no matter what miners do. Even if every miner decided to create 1000 bitcoins per block, full nodes would stick to the rules and reject those blocks.

It just occured to me that some or all of these adapter failures happened because of the initial heat damaged caused by the gpu(s). eg. About a month ago, I had to reroute the gpu's cables because they were being slow baked by the 5850's vrm heat.

NEVER use a SATA to PCIe connector - don't know who the hell thought of that idea but that is just asking for a problem since the SATA connectors were never designed to deliver that much power.
How much power is SATA cable rated for?
I have 5830's that's undervolted, and was thinking of using SATA to PCI-E power cables.

Don't!!!
It can handle no more than 5 amps so no more than 50-60W. And the connector is the problem, not the cable, the connecting surface is too small.

IMO, just use PCI-E plug splitters. Some power supplies split a set of 6 wires (3 hot, 3 ground) to 2 6+2 plugs already (300 watts!). With SATA, you only have 1 hot and 2 grounds, and they are likely thinner gauge wire, plus the connectors are not rated for a significant power draw.

Here are the PCI-E power plug splitters that I use. They take in a 6 pin plug (or 6+2, but it only takes in 6) and output 2 6+2 plugs, essentially adding one additional PCI-E plug per splitter. I love them. They are $3 each with free shipping if bought in volume at newegg. http://www.newegg.com/Product/Product.aspx?Item=N82E16812198018

Your lucky then. I used mine for a while too. First failure killed the power supply. Short circuit protection failed I guess. They after I thought I had gotten rid of all of them I discovered I still had one on the 6 pin on my 7970 which failed. Now I'm still waiting for my 7970 back from rma. They short in the connector itself (heat melts plastic just enough to short 12v and ground which conveniently are right next to each other), like the other guy said its not the wire that fails. Its not worth it.

 My 7950s (well some of them), are heavily undervolted, and they run fine on those adapters, but... I woudnt try to run a 5 series on them, they are power hungry bastards Smiley

Gutsy move with asics around the corner.  Right now you are looking at maybe $65/month gross assuming no change in diff.  Expect that to be reduced to $20/month in about 1 month and less than $5/month after that. I'd be surprised if you see a payback period under a couple of years.

About 185 euro a piece with taxes off Smiley. The trick is  I have free electricity, and I will be making about 11 btc a day tommorow. And about asics, everyone is entitled to their opinion, and what is more important, with all I made from bitcoin so far, I can afford the gamble. For me, at this price for cards, it was a no risk investment.

The other sure thing is ... I'm done holding my breathe on those asics. They have been 'just around the corner' for my entire 4+ months of mining. lmao

Have fun setting that up. I'm droooling just thinking about it. Grin

I will be making about 11 btc a day tommorow.

There would be a 3% PPS fee or earnings variance in case of a DGM pool. And difficulty is projected to double in a month, hopefully BTC-Euro prices will keep up.

Looking to review Bitcoin / Crypto mining Hardware.

With 11 btc a day, I am paying of more than one card a day. In a month all cards will be payed of. And if it stops in a month, I will sell them, still making a nice profit. Altough I am not sure the difficulty will double. I am waiting for few updates from microsoft, regarding exploits. Theres at least 5TH out there that showed up in last few weeks, posing as ASICs, and they are in fact  botnets. This is a great time for running coinminer for cpu via stratum proxy and posing as an asic, since the pool owner can not tell if its real or not. Simply, its the real moment for botnets. Just look for users with like 30-50% oscilations in their speed.

Undervolted 5830 pulls about 120w? If it is 50-60w per SATA connector, then I should be fine.
Use one original PCI-E, then one SATA to PCI-E on the 5830. Also, I can always put the SATA connector on cards that run off of PCI-Ex16 slots.
Since it is NOT the cable that's the issue, but more the connector, I should be fine hooking up 2x SATA to PCI-E on the same line that came off the power supply. You know, each cable have like 3-4 SATA connections.
