Why would you want too?
The main reason for grounding is electrical safety, I.E to provide an integrated environment, where electrical goods can operate within a safety cage.
Then the US goes and does something stupid like have 2 pin plugs!!!! (which are reversible....)... hay let's not even put the Live feed through a fuse safely..... (if the fuse is on the neutral line and it blows... then the equipment is STILL tied LIVE!!!)
First, decide WHY you want to do it... then get back to us.
Huh? US uses the 5-15 (3 pin with ground) socket mostly... The 1-15 (two pin) are only used for double-insulated small appliances, and the socket hasn't been approved for new construction since 1965. Reversible does not make a damn bit of difference, it is AC power, and the breaker is on the live side. The 5-15 is no different than the BS 1363 (British plug) except the 5-15 doesn't have that stupid fuse in it that's a pain in the ass to replace. The reason the fuses are in the BS plugs is because British standards allow large circuits (up to 36A) and the fuse will blow if the equipment shorts. In the US, they use smaller circuits tied to breakers (1 circuit per room or area) where if a device shorts the circuit, the breaker trips. IMHO the US system is better... two weeks ago, I had a power strip go bad, and had to walk all over the house switching off/on outlets and resetting the breaker to troubleshoot where the short was occuring since almost ALL the outlets in the flat are on the same circuit. |

That's almost the exact design of my rig, but mine takes up less area by:
- raise the cards a slight bit (to allow the PSU under them)
- use a 2.5" drive & rotate it 90°
- bring the PSU closer to the drive (under the cards)
IMHO that empty space next to the PSU is just wasted.

There is loads of 12V capability, solder some wiring to the relevant pins and crimp the other ends into a PCI-E molex. Done.
I've never crimped a PCIe 6 pin before. How would you go about doing that? Tools, extra jacks, etc? Pretty simple providing you have the proper tools. Basically, you buy a kit that has the molex connectors themselves, and also the pins. Strip the wire, crimp a pin on it, then the pin snaps into the connector. Here's some linkage: http://www.overclock.net/t/1136451/molex-atx-power-supply-connectors-and-part-numbers |

Hi! Thanks for your wonderful site! Please add Worldcoin - it would be even better then!
It's already there! Worldcoin Worldcoin scrypt 60726 4.78159022 32 0.000415010 mcxNOW 124.29% Huh? It's not listed on the dustcoin site. +1 for Worldcoin. |

Jesus guys.. just reading this makes me think of the days in elementary school... "My Dad could beat up your Dad."
Does it really make a damn bit of difference where a freaking PSU is made? All of Apple Inc. products are made in China. Does that make them cheap? By looking at their sales figures, I don't think so. If a PSU is rated (especially an enterprise-grade unit) for 80A, then it'll probably do it. Effeciency, i don't know. I'd have to buy one and load test it with a kill-a-watt to tell ya. Yes, it does have a bunch of odd pins on the back. They are not ATX spec units. So, if you want to use one, you'd probably have to do a little research and testing with a multimeter. Then some soldering. There is loads of 12V capability, solder some wiring to the relevant pins and crimp the other ends into a PCI-E molex. Done. please quit this stupid "My e-penis is bigger than yours" competition.... it hurts the brain.

If the PSU doesnt have a switch and the label says 110-240v then it will auto switch. I would be more worried about your electrician friend replacing your breakers with 20A versions without checking whether the wire gauge was thick enough on that circuit to support the increased current you plan on drawing. If it's too small, you'd have to replace the wire with thicker gauge before using 20A breakers. Unless you really are itching for a house fire, that is.

That link is straight awesome. Has i used it instead of buying everything from Newegg, I would have saved $80. However shipping costs from multiple vendors instead of one may eat up the savings. Thanks! |

Interesting, So I might be able to swing 5 cards with my existing power supply? BTW, I will be mining LTC. How will this influence power draw versus BTC?

this is what you can do... send me 1/2 the going rate for a jala in BTC, I will kick you in the balls and keep your money. You are now officially 'up to speed' with those of us who have pre-ordered BFL products.
ELLLL OHH ELLLL !!!!  |

Okay, i've read like 13 posts regarding power, and was contemplating expanding my rig. The parts are in the mail for my rig (should be getting them in a day or two)
I have a kill-a-watt, and could probably figure this out myself in a week, but i wanted to ask here so I could be proactive and order parts to enable a 5th card. (if possible)
So, heres the question: Running this rig:
Mobo: ASROCK 970 Extreme4
CPU: AMD Sempron 145 (single core)
RAM: 2 x 2GB DDR3
PSU: Seasonic Platinum 1000w
4 x MSI R7950 Twin Frozr
I assumed the following: Mobo, CPU, RAM & one 7959 = 300 watts. Each additional 7950 = 200 watts. So system laid out above should equal 900 watts is the cards are slightly undervolted.
Do you think I am correct (or incorrect) in assuming I will (or won't) have the power for a fifth card? (1100 watts?) Would I need to upgrade to a platinum 1200W?
BTW, three cards are running unpowered risers, and one x1 slot is using a powered riser. i assume adding a 5th would require a powered riser.

I hate it too, but it's better than stupid noobs posting stupid questions about things that have been asked 1000000 times, and are just too lazy to read. Having this rule kinda forces them to read first.

Once people stop hoarding and speculating so much and start trading it, it'll even out to $100-$150.

I think I will return the favour.
I don't know why people keep calling it a scam. They came through with their FPGA's, so it's hardly a fly-by-night organisation - they are designing their 2nd generation mining product in the ASICs.
They just came up against a lot of issues in manufacturing a massively cheap (comparatively) product, at the cutting edge of the technology.
It may not be acceptable for them to have taken so long about filling their orders, but in this type of business, what seems like a minor issue can stop production for a long time (take the example of the UK goverment's "smart meter" for monitoring electricity usage they wanted to create for home use - it has suddenly been delayed by over a year, due to design issues, and that's just an electricity meter, ffs).
Basically, they will deliver, but it will take a while. At least while they aren't delivering, the difficulty isn't going through the roof, so people still mining on GPUs are still profiting.
Anyway, off to find that ignore button....
+1 The bottom line in investing money into anything... DONT INVEST MORE THAN YOU CAN AFFORD TO LOSE. period. And if anyone thinks/thought BFL ASIC's weren't an investment, then you have no business being involved and don't deserve an audience when you cry foul about the delivery date. |

Question is whether mining LTC is the best use of your resources. I've found going to Merged Mining (have a look at bitminter.com for example), has led to more consistent and better yields beyond the single moment market snapshots. I was converting any LTC I had anyway to BTC- and this reduces the amount of trades needed- increased the stability of the miners when you push them hard to maximise Hash Rate, and ultimately- is a safer bet.
have you seen this? http://dustcoin.com/miningIt gives you a good idea on which coins are the most profitable per KH/s-MH/s. |

I've been running estimations (using charts & BTC/LTC history as a yardstick) and I think the price will probably rise up to $6 within 2/3 months then hover between $5-$8 for awhile. Difficulty is harder to predict however...
