Look at the Corsair CX750M for example, its 750W rated for 12V yet uses 2x18AWG cable rails for that. Do you think they'd sell something potentially dangerous with 375W per 18AWG cable rail? I've 100%+ed that PSU and while its toasty its certainly within limits.
That Corsair CX750M is a real hunk o junk. I have 4 dead ones here from over the past year. One wouldn't even push 500watts out of box without shutting down, two popped with shotgun bang and accompanied flames, only the last one died quietly, probably because I wasn't there to hear the screams. They were by far the cheapest most sloppily made pws I ever had in my mining setup. I would laugh at the thought of even including them in my mining toolbox at this time. I've been running 3 of them @ 100% for nearly 2 years, no problems here. |

I have nothing to hide, it's just that I don't want users "stalking" me when it's not needed. I don't like knowing that there is a chance of people following me around when I do something. It's just my personal preference, although you can see my posts, I feel a little bit more safer? I like my privacy. If you know what I mean. I'm horrible at explaining.
I do understand what you are saying, but i fail to see logic behind it, and at this point ill stop even trying, because it makes zero sense, to me atleast. cheers I think he means a tool to block someone and make that someone not be able to see his posts never again?? I dont know how that would work and it would be kind of stupid but i think thats what he means No. Basically I don't people having easy access to being able to watch over me. I don't think that would be a good idea. Someone could easily get around this by simply using an alt account to receive tracking notifications. You don't even need to be logged in to see posts. I think scammers would likely use this feature to avoid people noticing that they are attempting to scam (the same could be said about spammers) And those that use shills to follow others round the forums abusing them. I don't think the potential benefits of this feature outweigh the possible abuse. |

Jesus thats nice... And that SHOULD of been the C2.... I doubt there will be a C2 sadly I think problem with C1 stopped it. I blame sycooling for a lot of it. They don't even log on here anymore it seems. I would be interested to see the number of pump's that died in total. Would have been nice to do a C2 but yeah those pumps.... Don't get me wrong, for probably $10 they worked well when they worked, but no one likes failures. |

So as a business man, I would always go with the SP35, unfortunatley you can't get them anymore... So I need to go with the S4+, which is not so bad neither, but the device should be 2 U to make more profitable.
Everyone is screaming for Hashrate/Watts and Hashrate per USD, but you if you want to scale big, these are not the only things to take care of...
In your own comparison the S4+ is lower $/GH and W/GH, with your only gripe being you can't put 77Kw in a single rack. In what sort of facility are you going to be limited on foot print before 77KW per rack? |

can you mine both scrypt and sha256 with these chips AT THE SAME TIME or do you have to pick an option either/or on the chip and go with that only?
While its not been super 100% explicitly stated recently, it appears so and its the same as their last chip. |

Its 18AWG.
not good but thanks for an honest answer. if I buy this with 2 s-5's I will be pushing the wires at freq 375 and higher. Why would it be? S6 @ 375 is no more than 600W pre PSU = 150W per cable strand = perfectly fine on 1 68AWG. On tubes we were doing 250-300W per cable strand on 1 68AWG which was the sensible limit. you somehow went from saying its 18awg to justifying the safety of 16awg wires. If this is made with 18awg, thats not good. It might be fine for an S5, where you occupy all 4 connectors with thier own 18awg wire (and could fit 3xS5 on the 1600W PSU, possibly with a tiny amount of underclocking if required), but for a lot of other hardware (ie: anything that would draw >180w/cable) its dangerous. my rule of thimb is that 18awg can handle a maximum of 150-200W depending on the cable quality. 16awg can handle 250-320W depending on the cable quality. I would much rather see bitmain offer this PSU (or as a secondary option) with 16awg wire for a few dollars more. Fixed, I was talking about 18AWG but wrote 16. As I said before, anyone powering tubes with 18AWG would be doing 300W+ from their cable rails. Look at the Corsair CX750M for example, its 750W rated for 12V yet uses 2x18AWG cable rails for that. Do you think they'd sell something potentially dangerous with 375W per 18AWG cable rail? I've 100%+ed that PSU and while its toasty its certainly within limits. |

Can you PM me what you had in basket and going where please? |

I am curious to know. What is the "normal" temp while hashing for this S4+ ? I can't find this information.
printscreen with temparature right now, it's running in our datacenter. Oh nice, you could slap on 225 reasonably easily then as W/GH goes up nearly linearly. [Note that's near the limit of the PSU, and WILL void your warranty]. |

No, I stand by what I said. It'd be fun to see someone hook one of these up to a Neptune thinking "oh, 1600W is plenty" and see the jackets on the 18AWG wires wilt off within a few seconds before the whole thing starts burning. The PSU itself might survive but not the cabling. It's a terrible idea (I can't in good conscience ever recommend anyone run Neptunes) but if someone does it I'd like to see video.
Be much less fun if it had 16AWG wires. 150W on 18AWG is probaby okay. 8-pin PCIe for GPUs are probably mostly 18AWG and those are rated for 150W by the standard, which means they're probably capable of more, and 8-pin PCIe only has three power leads.
But remember that there are two 8 pin PCI-Es per cable rail = 'rated for 300W' on 18AWG. We're running a single PCI-E per cable rail on this PSU. |

So, does this mean that you will only provide support for people using Bitmain(Tm) power supplies for future miners?
Or is this just me being paranoid?
Extremely paranoid  As long as you're not using a 300x 12V rail PSU made by SUPERHIBIGPOWERWOWLED corporation, I'll help out where I can. Holy shit.. Be careful with these things guys... I'd advise everyone to be careful as hell if you are buying these and make sure you inspect them inside and out.
It has short circuit protection, as it worked in this case. I'm not sure what the point of that drilled hole was, but it will get fixed. |

Though 1600W at 12 cables is only about 4A per wire... That'd be good enough for most things. I'd like to see one of these hooked up to some Neptune cubes and watch the entire setup burst into flames though.
Fixed  By the numbers this is a nice-lookin' PSU. I hope Dogie's right about the fan not sounding terrible, because every 1U fan I've listened to (for example DPS800, DPS1200 and all SP rackables) are super annoying. It'd be nice to have user-defined cabling too.
That's what I expected to, thought I'd have to stress test it during the first day then turn it off but nope, I actually can't hear the fan in my setup. While I can't tachometer it (blades are too small for a marker dot), it does look pretty low RPM. Maybe we can have different cabled versions in the future. |

PCI-E cables 16AWG or 18AWG?
Good question, I'll try and find out. The spade connector version used 10AWG. Its 18AWG. |

Well, I cannot sleep, so I'll just comment on this: I have a Satisfaction Guaranteed policy.
Nice Policy. But... Guaranteed/Backed by what? dunno You are anonymous and refuse to identify yourself. You report to no one - you can close down and run off with the coins at any time. The coins are non-reversible and cannot be claimed back. You cannot be held accountable civilly or legally. Your guarantee is not worth the time you took to type it.  I thought that was made clear in his business' name  |

Ponzi ? So you are a Scammer...
No. I am tired of explaining the same to every new player. The explanation is given below in the PM I sent to Vod. Probably, I made a mistake by chosing the domain name, but the game is designed in a way, so that running away with the bankroll wont be economical to me.
If you have to explain that you're not a scam to your average customer, you should consider a rebrand. |

Yes you can SSH in but its still not going to get very far. There simply isn't enough headroom and even past the chip, the board components themselves are pretty stretched as it is. |

I don't see any other way that that could be interpreted? Clearly designed to appear as a non profit / charity.

PCI-E cables 16AWG or 18AWG?
Good question, I'll try and find out. The spade connector version used 10AWG. Noise? and at what fan speed?
I couldn't notice the fan noise even during a 45C ambient test, unsure on the RPM but its not quick. Fan speed variable or fixed?
This unit can 100% load @ 50C and 80% load at 60C so I would have thought it was variable to hit those higher numbers. Who is the original manufacturer?
I doubt they'll say who the OEM is. S4+ sales must be terrible if your resorting to this. Maybe you should lower the S4+ price and we would buy them.
It was always the plan to sell the PSUs. |

So is anyone out there overclocking this thing yet? Any idea how high can you safely go with it?
I don't remember there even being clock controls via the UI, so you'd have to SSH to cgminer. There really isn't much headroom on these chips even if you had control, especially in any sort of ambient temperature. The chips end up thermal throttling quite easily. |
