I would not give him any more advice as I am thinking he is a troll?

You may be stuck buying a 1600w PC PSU which will take 120-240v.
I can't say how well they will take constant voltage changes, but if it's within the range they will certainly work.
Look up an eVGA 1600w G2, they're around $360 USD.

my method of underclocking to freq 462 and buying the evga 1300 g2 is better

he saves 160 usd maybe more.

he runs at 9.9 th vs 12.0 th

so he loses 2 th.

gear is much quieter much cooler

if it is hot desert he is well off.

2 th is going to earn 160 usd in about 7 months. So he would be ahead of the game for the next 7 months. with the evga 1300 g2 and a downclock.

plus much much much much less noise.

and less heat

This. Maximum hashrate is not optimal solution.

I gave up I led him to the water and he won't drink it.

I did the same trying to explain quality of PSU's and he kept picking new one's. I don't get the urge to use 3 or even 2 when 1 is best. The scariest one was the 3 500's he had picked.

I still worry about op's electricity "i have free electricity but its very bad which moving all the time between 185V to 220V ( using voltage stabilizer! ) without stabilizer it moving between 145V to 180V". Sounds like he's starting out with pretty bad electrical to begin with.

Do you have a free or very cheap electricity?
Do you have already a powerful enough conditioner for cooling miners?
Are you confident that in the future you will not buy more miners ?

free electricity
i will user air condition 1.5 hp in (2m*4m) room size and i will use tube like this in picture to transfer heat outside room
i can buy more in the future and put all in this room

https://i.imgsafe.org/d4df7ca9bd.png

So you want use this http://www.lg.com/my/home-air-conditioners/lg-BS-Q126HXA1
with COOLING CAPACITY 12,000 Btu/h for remove heat at least 2400W heater. (2x S9 )

Do you know that the air conditioner is going to melt mode ? 5 minutes no frost at all.

I hope your air conditioner is with good warranty.
But you do not have to worry about it . LG Inverter does not work with 180V

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!!!

Im currently hosting my S9 at my house now using an EVGA g2 1600W from a wall outlet also. I chose to underclock for this exact reason, and also just to be safe. I saw a lot of Phils posts saying that they should be underclocked for many reasons

these are the batches. all have 189 chips all have 2 fans

if bitmaintech made the clocks drop from 650 to 550 and kept the fans and the chips the same it seems like common sense to clock them all close the the batch 5 number of 550 rather then the batch 1 number of 650

batch 1 14.0th freq 650
batch 2 12.93th freq 600
batch 3 12.93th freq 600
batch 4 12.93th freq 600
batch 5 11.85th freq 550

my one at home is clocked to 462 until I move it to the array

my four at the array are clocked at 600 with monster fans action.

Air conditioning is not a good idea for mining.

why ?

It's probably best to say that "Air Conditioning is not cost effective" for mining. It isn't bad in the sense that it will damage your mining hardware, or decrease your hash rate.

One way to think of it is that you can think of an S9 as a 1500W heater. Would you want run a 1500W in a room that you are trying to keep cool? In general, the answer is no.

Depending on your environment, you may or may not have much choice. Just consider this in your planning.

i will get 3 EVGA 1000GQ 80+ GOLD from amazon
but how to use 3 PSU EVGA 1000GQ 80+ GOLD to power 2 antminer S9 ?
each EVGA have only 6 PCIe ( power 2 boards )
how to power the controller on both miner ? i still need 2 PCIe

At Your own risk. if the one PSU which gives power to controller shuts down, and 2 blades stil receive electricity from the second PSU, then these two blades overheating and may burn down. (Happened to me with several S7)

can i power two board with EVGA SuperNOVA 850 ?

Technically, yes. If you use it for S9 Batch5
but better PSU for that is Corsair RM1000
and for one board and controller buy Corsair CX750 (Not 500, 600 )

You Must use a circuit is controller said PSU shuts down, that it turns out the second PSU.

Let him go with Cooler Master PSU, it's a free forum where he belongs. If he comes back here crying, my miner burnt down my house, then we'd know for sure Cooler Master really sux!!!
