I have a 1000 watt power supply with hookups for modular cables but it didn't come with any but I think I know what I need to buy for a Antminer S3 - a 12 pin to dual 6+2 pin pci connector. What I don't know is what port to put it in once I get one. Does anyone know? This is an Enermax1000 87+EWT. Thanks! ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fs3.postimg.org%2Fjnzcqebn7%2Fpsu.jpg&t=665&c=PeZrhX_pLyCXxg)

GPU port I think. I had my ZM Hurricane connected to that.

All I use is EVGA modular power supplies. My Antminers and Zeus Miners hook up through the VGA ports.

Watch out for the pinout if you buy the cables separately! I made some of these cables myself for different brand PSU's and the have different pinouts. For the Enermax it's easy because the pinout is written on the PSU. If you buy 16AWG cables you only need 1 cable per S3 (1 connector for each board).

yeah but the two cables can not run off 1 jack. his psu has 30 amps a jack it is 4 rails. no one rail. so he will need two jacks which will each have 2 plugs.

So if I use the native cables for my existing S3 (plugs into two sockets) then I would buy two additional cables 6+2 pin PCI and plug them into the red ports and then the other ends into all 4 sockets on the second S3? Does it matter which red ports I use for the two cables? On the S3, if it is facing long ways so I am looking at the logo, for each cable I buy, do I want to plug in the connectors to the sockets left/right from one another or up/down from one another? Thanks!

Most PSU's 8 pin CPU cables reverse the polarity at the end of the cable...some do not & reverse inside the PSU,be sure to check which your PSU does.

I am sorry for any mis-ionformation, looking at the .pdf of the offered specs for this power supply it is unclear how the rails are wired, it may well be that one internal rail provides both MB 12v power AND powers the 2 integral PCI-E connectors, I would hope not, but this may be the case. The chart for the 1000w suppyl shows TWO 'native' connectors, and TWO modular ones, and I would suppose that each of these FOUR would be on a separate rail, (with the MB connectors sharing one, but we would not be drawing off of this) however the picture appears to have THREE of said red connectors, so I have no idea how these might be wired internally, as the pictures offered do not match the chart! If your wires are getting very warm to the touch, you are drawing near the limit of power and should explore alternative configurations, this supply, as others with 30A rails MAY be able to power an S3 one one rail (I've seen it many times, and consider it a fire hazard), but your wires would be getting quite warm and your supply's capacitors and transformer(s) would be over-taxed and this is not a good thing. All that said, your supply has FOUR individual 12v rails, which should be independent of each other, if you are handy with a multimeter, you may be able to figure out which is which, otherwise dig for more specs or examine the docs for your PSU and each of these rails should power ONE hashing board, or one SIDE of each miner. If you can get one rail per board, you will be solid. Good luck! Edit: Looking back at the pic in the op, IF the cable pictured that represents the TWO 'native' PCI-E connectors listed is of the BRANCHED type, meaning that it is just a short jumper that provides the second connector, then it is highly likely that, as mentioned, all THREE modular connectors would be required to run two S3 units from this power supply.

I would add one caveat to Phillip's excellent suggestion. The server PSU he mentions will only deliver the 1200W described when it's supplied by a 220V power line. It's de-rated down to 900+ when powered from a 110V line. This is clear on holybitcoins page, so it isn't sneaky or anything, just something to be aware of.
