how much each hash board consume in S7 & S9 ?
S9 1200W for all controller and hash board
so how much I/O controller need from this 1200W

I finally understand it now.. So it is much safe to be using a PDU as compared to running it from the outlet.
1. PDU offers extra protection
2. save cost as you would only require 1 outlet from wall as compared to lots of outlet installed.
More or less, yes that is correct. If you plan correctly and get all the right equipment, you can safely plug multiple miners into one wall receptacle via a PDU. Keep in mind, the most important part of this whole thing is planning properly.
You need to know:
-amperage rating for your current electrical panel
-how many unused spaces in your electrical panel
-how many miners you want to add within the next 12-24 months
Once you have these facts laid out in front its easier to plan and easier to get usable advice.
Does that mean that PDUs is much more cost effective as compared to plugging it directly to the wall?
I think you are missing out on the reason for the PDU. If you had a wall plug for each psu (with proper voltage and amps) you would not need a PDU. This is more common in say 110-120 volt. But a PDU allows you to take one big power source (via the outlet) and distribute it to many item's. For example say you have 240 30 amp running to your miner's most likely you will need a PDU to take it from the outlet to your PSU's.
It's more about being a necessity in some setup's then the cost aspect. But you could save money running 1 wire to it vs many lower volt/amp wires (but this could very).

I do understand that PDUs distributes power. But i suppose that we're good to go, since we installed 1 plug point for each miners. Isn't that so?
Why would we need PDUs, since we can just install one plug point per miner? Is there something im missing out?

It sounds like you are good to go for your current setup! The only reason you would need a PDU is if you want more miners and you dont have enough space in your main electrical panel to wire in another plug. Is that making a little bit more sense?
Thank you very much for the explaination!

so you want to do
30 amp
fuse in box..................plug in wall..........plug in wall........... plug in wall......... plug in wall...........plug in wall.......plug in wall
correct? so 3x 2 plug receptacles are 38 bucks
6 special power cables are 90 bucks that is 128 dollars.
you need 3 wallplates and 3 boxes for the walls as I for one would not put all into a 3 gang box. so 10 -15 more.
so 153 in parts. no extra fuse protection offered by the pdu.
but i do not know full code for your area.
I am usa based so code for above is this receptacle wait for link
https://www.amazon.com/Leviton-5822-W-Receptacle-Commercial-Grounding/dp/B000U3I1S0
now see photo below 12.72 for one which does 2 plugs
if you do a 30 amp fuse at the box and buy 3 of these you could do 5 s-9's at full speed or 6 s-9's with a down clock.

I will be honest some of your questions are a little scary to me. Is this something your wiring yourself? Or is wiring already there if so take a picture of plug and we can say more.
What a PDU does is allow you to run one cable with a lot of amp's to power multiple miner's. This varies on your voltage and number of amps on which PDU is right for you if any, there are a lot of different options. But basically your PDU plug's into your power outlet and basically split's it where you can power multiple miner's from it (assuming power is there). *Edit Better description then mine I think is here - https://en.wikipedia.org/wiki/Power_distribution_unit

PDU's matter for those who wish to run more than one or two high powered miners. Once you decide to run more than one or two S7\S9's you really need to think about how to run power to the devices safely and efficiently while also taking into consideration the number of slots open on your electrical panel.
Initially i started off with a NEMA 6-20R Leviton 5824 20 Amp, 250 Volt, duplex receptacle which allowed me to power two S7\S9 off of one circuit. In my electrical sub-panel, i have a total of three (dipole) spaces. If i used a single duplex receptacle per circuit i could only hook up a total of 6 miners (2 per circuit).
However, by using a different receptacle and adding a PDU i was able to connect four miners per circuit giving myself 12 total connections on the same space in the panel. I ended up settling on using a NEMA L6-30P Leviton 2620 30 Amp receptacle since it is a fairly common connection for PDUs. I also went with a Tripp Lite PDUH30HV19, was a little more expensive, but it fit the bill.
...As mentioned previously, none of this really matters unless you're trying to plan for running several of these high powered machines...
to chime in quality used pdus on eBay for 50 usd are easy to find.
this is a 30 amp version it should be able to run 4 apw3-12-1600 psus
http://www.ebay.com/itm/30-amp-8-outlet-PDU-With-Twist-lock-Plug-/251702276381?
so
fuse box with a 30amp 240 volt fuse>>>>>>>> 30 amp 240 volt wall socket that matches the pdu plug>>>>>>pdu>>>4 separate psu's
Hire someone that knows how to do this. This can kill you if you do a bad DIY!!!

PDU's essentially act as portable sub-panels by providing circuit protection to individual PSU's/miners, eliminating the amount of electrical circuits you need in total, and giving you flexibility in powering miners. Also, if you are hiring an electrician (which I strongly suggest you do) you save considerably on labour and likely materials by running fewer, high amperage circuits to your mining area.
I see. If that's the case, i think i should be getting APW3. As for power cord, is there any difference for power cords? I always thought that power cords are all the same.
The PSU end of the power cord is a standard IEC-13 connector. The wall end.... depends on what country you are in. There are a lot of flavors for the >200v plugs.
The wall end also can depend a lot also worth mentioning a lot will change based on what PDU you use (assuming you use one). Not all PDU's use the same connector going into them so it's worth looking at when buying a PDU. I personally have PDUs between miners and wall in all 240 connection's I have.
It is worth noting you can find some decent to great deals on PDU's on ebay from time to time. I owe phil for one he told me about once. But if your ever in market for PDU check ebay a lot as it tends to change on what is best deal.
Can i ask what benefits does PDU provides? Do we need them?

Ahh.. i think i understand. Apologies for not being a technical guy
Hey Finksy, that looks like a very good alternative. Was actually looking at a 1600W PSU for 300USD, with 5 years local warranty. Hard decision for me. I'm actually leaning towards 5 years local warranty, due to the reason that i'm not sure whether PSUs breakdown easily, and their usual life span after being used. What do you think?
To be honest, there's good and there's good enough. In my eyes, mining is still a business, so keeping costs in check is important. Why pay $300 for a PSU when $120 for Bitmain's (or $85 in the case of my IBM 2880W PSU's) will do the same job adequately and reliably? The more you spend on PSU's, the less you are able to spend on miners, plain and simple. Anyone that tells you otherwise either has constraints limiting their choices (<200V AC input or require SATA/ATX plugs for motherboard), has made a hobby of it and wants to show off their bling, or are delusional. The only other factor to take into consideration is PSU efficiency, and if at your given electricity rate the extra cost for a more efficient PSU is worthwhile in the longrun.
True that. I guess i'll be going for bitmain's PSU. Thank you!

I've been using Bitmains PSU's for over 2 years now. Currently have 24 of them running s7's and s9's 24x7x365 with most in 85-90F ambient, zero problems. Frankly, I love them. Pure plug and play with miners.
Sounds good. If i were to use other PSUs, isn't it plug and play too? Since there is no configuration for PSUs.
And yes I also have several of the IBM 2kw's and several HP-DP1200 PSU's using breakout boards. all work fine.

I have not had any issue's with APW3's. They are what Bitmain recommends with S7/S9. I personally have followed this and not had any issues on the PSU side. They have kept working for quite a while now on some as I sold S7's and kept the APW3's. They can power even the batch 1 S9's which had the highest hashrate's.
There will always be market of server PSU's with breakout boards out there. But until I have a problem I will keep using APW3's as far as S9's at this point. I am not knocking some of kit's out there as I have not tested them. So just making clear not knocking them just saying what has worked good for me.
At this point a lot of my ATX psu's I had laying around from previous gen miner's went to mining Ether. I have had a decent variety of PSU's over the year's. If you have the 205V+ it is the one I would go for. If under the 205V then I would look at the EVGA Supernova 1600 you mention, as EVGA does have some great highend PSU's.

Thanks for your input. Can i ask how long have you been using those APW3s? The reason why im afraid to use APW3s is because i'm afraid that it would breakdown after the warranty expires.
...
Since the launch of S7's, at that time I decided to use APW3's and so far I have not regretted it. They should last long after warranty if you have the luck I have had. A LOT of these psu's are out there and there are many user's. Also I figure Bitmain themself use them in internal mining facilities.... I don't think they would use them if big problems.
So I don't think you will regret decision as long as you have 205V+ and use a proper power cord. You do provide your own cord for the APW3's as there are so many different options depending on setup/pdu/etc.
