can i power two board with EVGA SuperNOVA 850 ?
The RM1000 is used by many miner's it has been tested. The Cool Master V1000 may be a fine PSU but honestly don't think it's of the same quality. But neither of these are really what people are using for S7/S9's. So it is kinda a moot point, but it certainty is better then the 3 x 500's you were looking at.
No offense is meant but you have gotten SO many good options mentioned on what to pick. Your local market might not have them, but ordering online and getting them is worth it. I just am going to wish you luck. You can lead a horse to water but you can't make it drink.

the rm1000 is a lot better quality then the 500 watt unit you mentioned.
but getting 3 to run 2 s-9's and using the amazon part is not what I would do.
good luck.
i talk about Cooler master V1000
its more efficiency
I do not think your right on RM1000 and your cooler master being of same quality. I have owned a few of the RM1000's they are good quality but I also use them for video cards/smaller miners not a S7/S9.
Your really going the wrong route with these budget PSU's on a brand new S9. You have a LOT of good advice and reason's why people choose quality PSU's. In the end we cannot stop you from buying cheap PSU's but if it goes wrong you really are going to wish you went for a quality PSU.
You might read warranty on S9 just the voltage surges would void warranty. I'm not sure why you want to add poor power supply on it, realize your buying a PSU that can last multiple miners. Or be sold after... all these ideas of cheap PSU's, adapters of unknown quality, ontop of your voltage scare me personally.
cooler master v1000 is not a cheap PSU
its same rm1000 price ( about 200$ ) and its 5 year warranty

Hey Phillip...
I noticed your strong advocation for down clocking...
A little off topic for the thread -- but:
I live in an ungodly large home for just 2 people -- so the noise isn't even heard 99% of the time...
However, I am plugging in a 1600W PSU into just a regular outlet (20 Amp circuit) for my S9. I've seen some of the awful pictures of other miners that burned -- Am I OK? Or should I consider sliding the scale down just a bit...
I know it says that it pulls 1300W -- but every time I check the kilowatt meter, it was between 1138W and 1194W -- temps are fine (air conditioned environment)...
I know that you are an expert -- and reading your advice about down clocking kind of mentally set me back a bit...
I'd like to hash as much as possible -- without risk...
Thanks!!!

they said (Power supply unit is not included. You will need an ATX PSU. There are 3 PCI-e connectors for +12V DC input on each hashing board and all 3 need to be connected to the PSU for the hashboard to operate. Do not connect more than one PSU to the same hashing board!)
i think about using 3 PSU (cooler master Extreme Power Plus 500W)
each one have 1 PCI-6
and i will use pci 4 to 6 adapter to get the other
what is your opinion ?

obey me or die. this is a joke
All kidding aside if you live in the usa and want to do that it would be really stupid cheap.
but since you said you have 140 to 180 volt power you don't live in the usa
this is my best choice and available in our market ( Cooler Master V1000 / 1000W )

Most likely you will need to order online on a PSU for a S7/S9. It depends on your market some have great local store's. But me personally I can order from newegg or amazon and get cheaper then local market and better quality.
You really need to get a quality PSU to go with your S9, I like the recommended APW3 but again with your voltage going up/down under 205V it's not a option. (Your voltage kinda scares me with such large varience, makes me wonder of quality of electricity). But again look at the EVGA ones mentioned... don't go for these low quality PSU's.
Ever since you mentioned 3 PSU (cooler master Extreme Power Plus 500W) + unknown quality adapters your PSU selecting has really scared me.

My opinion is, you get flaming cables and burned plugs .
this is my best choice and available in our market ( Cooler Master V1000 / 1000W )

You still get burned plugs possble on both ends. This is not a good PSU. I have used them a couple of pieces with EVGA G2 cables
which are directly tinned to PSU. Then it is durable and reliable for 2x S7 blades.
But after all, you're not going to get a new PSU to replace the cables. I got mine used with KNC Jupiters long time ago.

i have this power supply too

it have 6 (PCI-E 6 pin) so it can power 2 boards

I just bought the EVGA 1600 and it works fine -- already comes with all the cables necessary.
I did opt for the ATX 24 Pin bridge ($5) rather than using the paper clip method.

Buy a quality PSU using 3 not so good ATX psu's... just is not way to go. You are spending good money on a nice miner, getting a quality PSU is really something you should do with that.
Reading your first post the APW3 is not a option as it going under 205V it is not made to operate. So what they recommend and I have been using is not a option for you. Look up again at the nice EVGA's mentioned there is a reason why people are recommending good PSU's. I personally would go for the 1600 and not underclock but that is just me. The other is a option aswell.
But PSU's if you treat good you can use for multiple generations of miners, or sell just keep boxes and all your accessories. I would not touch let those cheap PSU's you mention and adapters (which we don't know quality of as no link) touch a new S9. Just wrong way to start mining with it.
i have also HEC Cougar CMX 1000W PSU
so i can use 3 PSU to power 2 Antminer like here

Don't buy a new miner only to under-clock it, you are essentially throwing money away if you don't gain any efficiency on it (which you can't unless you are able to provide lower than 12V through PSU)
no that is not always true.
i can show multiple cases where it is the correct solution.
this is one right here.
the math favors him to buy the evga 1300g2 not the evga1600 g2
That only applies if you are factoring the PSU price into your ROI. Depending on your long-term intentions, PSU's can be considered equity whose actual depreciation can be subsidized over multiple generations. If you are in it for a long time, you don't need to pay off the PSU with one generation of miner. By under-clocking your miner you are reducing it's value immediately, and have already lost money. If all of what he said was true, he may be better off finding a hosting solution for the same price/kW as he pays for electricity and not have to worry about power woes or varying voltage. Pretty much all hosting facilities have access to stable 200+V, which opens the door for WAY more cost-effective PSU's than the EVGA's by a huge factor.
