If it's two server PSUs load-balanced, its as good as a single-rail PSU. When one goes down, the other will too. I've been running miners like that for two and a half years.
So if you are running two 750w PSU together (I don't know the proper term) for one miner. What happens when one of the power supplies fails for whatever reason? Say that circuit trip, one psu blew, some idiot tripped over the plug, etc. would the other PSU safely shutdown?
Bad things can happen. Better get one proper power supply that can handle the miner by itself.

if linked in parallel and one dies the other would shut down do to overloading.

I have 3 acres of land guys!
Power cost is about $0.07/kwh
If someone wants to rent some of my land
I got plenty

Land is very cheap to buy... Only the property taxes are high.

Unlikely that any given rail is at least 400W? That's what you'd need for a single board to avoid stuff exploding.
Yep, sub-500W miner would be nice.

Alas each rail is like 250 W..
.. Might be 300 actually but all way to weak .I had to re-wire the power supplies to work with my S3 actually. Well.. by re-wire I mean just rip off the two 4 pin connectors for the CPU and connect them to a 6 pin. The PS kept dying when I first ran the unit, after some googling I found out I had to power each board with one of the 12VDC busses as one couldn't handle it..
Looks like I should of just gone with a beastly PS unit.. oh well. I will just continue to mine with my "New-rbox" and a few of your sticks lol.
I am considering buying up some land in Manitoba to mine though.. cheap power for businesses and cheap power in general. That or Quebec as I would probably need to learn to fly and buy a plane to make Manitoba viable.
Lol, electricity down here in Manitoba where I live is $0.07/kwh. It's really nice
Probably. You might have to pigtail the tach line back to the fan connector on the controller; I don't know how they behave with only one fan reporting speed.
Sidehack,
Can't you just plug the other fan directly into the other PSU? So if the controller shuts off the other fan will still be spinning?

This is why spazz is hoping for a 100-400 watt (preff closer to 100w) 16nm ASIC :S .
I am still considering an S9 but all the PS I have for my S3's won't cut it as they were cheaper PS and have two separate rails for DC... I have a feeling those DC buses won't play nice together :S.
(From Canada like the OP)

I would guess they keep hashing on whatever work was passed in last and then fall idle whenever that runs out. But they're doing it with no fans, and whatever power draw they pull at idle, all that heat would still be inside the box. Sounds like Tupsu has been on the receiving end of a problem like that with destructive results.
When the controller is shut off the other blades still keep hashing?
We (bitcoinpsu.eu) have one type that also delivers 1000w+ on 110v
At the moment we have some running in a 3 for 2 configuration (each PSU has 2 boards and 1 controller).
We're working on a load-share version, but up til now we didn't have any problems without it...

We definitely do have 240V here in Canada, almost all homes use "split" single phase, where the power in to your panel is 240V and separated to half-phases of 120V. As Virosa mentioned, oven and dryer plugs can be wired for PDU's to power PSU's. If you have either room on your panel, or two adjacent unused 120V circuits you can have an electrician convert them to a single 240V. If you do end up going that route, let me know as I sell server PSU's fully capable of running S7/S9's (2x units per 2880W PSU) and am also in Canada. The EVGA units are nice, but the extremely high price makes ROI much more difficult (they are $430 CAD on Newegg...)
Thanks, I will let you know. But first I will have to save up to even be able to buy an S9
Dell makes a 750 watt titanium server. If it has the same pi out as the standard 750 watt dell it would be great.
If you give me the,dell part number for the dell your board uses I will try to figure out if the dell titanium has the same pin out

I believe that his old board used the Power Edge 2950 PSU. I'm hoping for something similar to the 4k breakout boards where you can just stack or place side by side two 750s and the board plugs into both PSUs and bridges them for you or will it be something that you have to hardwire together yourself?
found the titanium version

2 for 75= 150 plus boards and cables maybe 210?
but the evga 1600 ti is 400
would consider this instead.. and it would allow the 120 volt player to use it.
I've had interest in something I was already thinking of doing, adapting the 750W board to take screw terminals or 6-pin jacks like the new DPS8/12 board. The all-in kit I would provide would be two boards with 6-pin jacks and 11 cables - one about 6 inches long. There'd be a jumper wire in there to tie the SHR pins together to load-balance the two PSUs, and you'd use the short cable to jack the two boards together and establish a common rail. That leaves five jacks per board just right for an S7 or S9.
I could build a single dual-PSU board, but since the same functionality could be provided with two regular boards and a $2 cable I'd rather not have to split my resources between two different board runs.

That certainly still works for me. I'm one of the people that prefer the 6-pin PCIe jacks over the screw terminals.
the 1600w G2 supernova is a good choice, even though its expensive. 10 year warranty - so you use it for 10 years full blast. Its quality built, connectors and wires are tough too. No risk of fire there. You should at least get a 20Amp plug on the 120v, or go 220v. ask an electrician, but its going to cost you 100-150$ just to get him to your door and get him to do some work unless you got a good plug for an electrician.
