Thanks for the replies.
My neighbor is an electrician, but I think it would be safer and easier just to go with the EVGA SuperNOVA 1600 G2. I didn't know it had 9 PCI-e connectors.
Thanks again guys!

Good PSU's are not a bad thing to have around they will likely still have value even if you decide to sell it one day. I highly suggest keeping all packaging/box/etc and put in corner if for if you sell that is what I did with all my old ATX PSU's.

If you get into it getting a proper 220/240 with PDU is very nice to have. You might check before you spend that kinda money on PSU if your neighbor would do it for decent. And I had some help from Phil which I'm still grateful to him for on my 240. Depending on your local laws/ordinances you might be able to do it yourself. I was lucky living on farm out of city where it was not an issue.

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.

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?

Hm... that is a good point. It'd take a bit of rigging but you could use the 500W to kick on the 850W, but then you violate Bitmain's recommendation to have the controller power up last. With a bit more rigging you could probably cross-latch them to avoid that problem, but if you know enough to do that you probably also know how to wire in a 240V circuit.

I'm working on a redesign of my Dell 750W board and hopefully a new batch, which with that you could load-balance a pair on a common rail and get 1500W with 10 cables off 120V for about a hundred bucks. Too bad a full production batch is more than a month off.

This is exactly what I've been looking for. I'll be waiting anxiously for this. Perfect right after the halving too so we know where BTC prices, difficulty and hardware stands.

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...)

Very nice for people "stuck" on 125V.

My fix was mining on my Oven plug, until i got 250V. I'm guessing cloth dryer plug would work as well.

Or get about an 850W PSU for two boards and a 500W PSU for the third board and controller.

This is a bad idea. If a 500W PSU shuts down and 850W not, then you can get with a few hours 2 overheated blades.
That's what happened my two S7 during warranty and with one S7 blade after warranty period.

no transformers!

what is this unit in ca?

note you must run it alone on your circuit

So the new, amazing Antminer S9 just came out... And I really want to buy it!
But the S9 needs to be powered at 1375W, and with 9 PCI-e connectors (3/board).
The recommended power supply is the APW3.
The APW3 needs over 220V to run, but I live in Canada, and in Canada there is only 110V outlets.
Currently I'm running 2 S5 antminers on one EVGA SuperNOVA 1300 G2, which has just the right number of connectors, which is 8.
So now I'm either looking for a PSU that can do 1600W and has 9 PCI-e connectors and hope it will be enough,
could use 2 PSUs to power one miner,
or get a 110V -> 220V transformer and hope it doesn't blow any boards or circuits.

Please help me out you wonderful people
