Part list help!

You don't want to run PSU's close to the rated the capacity. They won't be as efficient and it will shorten it's lifespan. 50% to 80% of the rated capacity is where PSU will run most efficiently and cool. The other consideration is how many PCI-E connecors you need for all the GPU's and risers. Many PSU's less than 1000W will only have 4 PCI-E connectors per PSU. For 13  RX 570's you will need a minmum of 13 individual 8-pin connectors just for the VGA power. Some cards like the Nitro+ also have a 6-pin connector that may be optional. For risers I use 6-pin PCI-E risers only and connect two or three risers per PSU 8-pin cable using a PCI-E 8-pin to dual 6+2 splitter cable, figure another 5 PCI-E PSU ports for the risers, so in total you need a minimum of 18 PCI-E ports.

Wow thanks alot for that and everything. That has clarified alot for me. I didn't realize you have to run risers off the PCIe ports on PSUs.

 You CAN run them safely via MOLEX adapters - and there are some with all 3 connections that are the recent "4 cap" versions.
 The COBOC ones Newegg sells as an example, seen the same design from a few other places.

 You don't HAVE to run 19 cards from the ASUS B250 Mining Pro to make it worthwhile - the on-board power supply management is nice, and saves a few $$ + is simpler vs having to use Add2PS type adapters.
 If it's lower cost vs a 13-slot MB, it's DEFINITELY the better choice.

 NewEgg has a Canadian branch, can't hurt to check them in addition to the other sites you mention.

 I strongly recommend use of the EVGA G2 supply line over the G1 or the GQ or the G3 - the BALL BEARING fan is going to outlast the "fancy name sleeve bearing" junk in the other lines.
 I'm not 100% sure on the G2L line - I think it's also ball bearing fan, but the power connections are kinda wierd and do NOT match up with anything else at all.
 I can also recommend the Seasonic X-series, but those are in very short supply and getting way expensive when you CAN find them any more.

I already pulled the trigger on the pcie risers. They only have 6 pin on them but they come with a 6 pin to sata connector.

Ok I am definitely gonna grab the Asus board and 2 EVGA G2 1000w. Thank you.
What do you think of the Corsair HX Series HX1200 ($289.99) or Thermaltake PS-TPD-1200MPCGUS-1 ($232)? They are almost $100 cheaper than the EVGA SuperNOVA 1200 P2 ($369)

I am just not finding good prices on newegg.ca
I am gonna order mostly everything from www.pc-canada.com  they have discounts on bulk orders as well.

I am still not 100% sure on 570 vs 580
4gb 580 $325
8gb 580 $360
vs.
4gb 570 $284

[QuintLeo]

Corsair - is iffy, it depends on who is making a specific line for them as to if it's any good or not - and I've given up on trying to keep track of them, since their GOOD lines are mostly Seasonic made anyway (I think the do use SuperFlower for one of their good lines, like EVGA does for the G2).

 Thermaltake - I've not been impressed with ever on power supplies, though they make some good cases.

At your quoted prices, the 4GB 570 is probably the best option - it will be lower hashrate but close enough that the ROI on it should be somewhat faster, which is CRITICAL if you plan to mine ETH on them given the very "up in the air on when but being actively worked on" of ETH moving to Proof of Stake.

Ok here is my list, if everything looks good I'm gonna go ahead and order it

ASUS B250 MINING EXPERT
$181.99

DREVO X1 120GB 2.5 Inch SSD SATA III Internal Solid State Drive
$69.99
 
Ballistix Sport LT 4GB Single DDR4 RAM
$59.99

Intel Celeron G3900
$53.99

ROG -STRIX-RX570-4G-GAMING
13 x $280.39

Gold POWER 1800W BTC power supply
3 x $167

For the power supplies, I'd recommend getting 3 of these:
https://www.aliexpress.com/item/New-and-original-Gold-POWER-1800W-BTC-power-supply-for-R9-380-RX-470-RX480-6/32825827647.html?spm=a2g0s.9042311.0.0.xNt9Ym
Im running a mining farm with 48 of these PSUs for the past 8 months, and none of them have failed, you get ample power, and running 6 cards on each.

So for these psu's they have 12 PCIE cables? Should I connect it something like this:

PSU # 1
atx
cpu
PCIE1 = gpu1
PCIE2 = riser 1
PCIE3 = riser 2
PCIE4 = riser 3
PCIE5 = riser 4
PCIE6 = riser 5
PCIE7 = riser 6
PCIE8 = riser 7
PCIE9 = riser 8
PCIE10 = riser 9
PCIE11 = riser 10 & 11 (splitter)
PCIE12 = riser 12 & 13 (splitter)

PSU # 2
PCIE1-6 = gpu2-7

PSU # 3
PCIE1-6 = gpu8-13

wow, that is not easy at all

[millsys]

ROG -STRIX-RX570-4G-GAMING  13 x $280.39 = $3,651
Hash Rate NeoScrypt is about 8,000 kH/s
TDP 150W (90% is 135W)

Asus GTX 1070  8 x $433 = $3,464
Hash Rate NeoScrypt is about 8,000 kH/s
TDP 150W (90% is 135W)

5 LESS cards will result in the same hashing power for $190 LESS!

You will also save 675 watts and have more room to add on later!

That 1800W power supply is NOT rated for 120V US power.....  It might work, might not!  You need about 1300 watts at 100% or 1180 watts at 90% card power.  
Two of these will suffice for $120/ea - https://www.newegg.com/Product/Product.aspx?Item=N82E16817151188

G3930 is cheaper - https://www.newegg.com/Product/Product.aspx?Item=N82E16819117748

are you giving me USD prices?
ive been posting in CAD.
The cheapest 1070 I can find is $534.9 (newegg.ca)
8 gtx1070 = $4280
13 rx570 = $3651

oh and good catch about those PSU's I didn't notice the 200v input thank you

[millsys]

Yes I'm using USD

Even the spread, you would run 5 less riser cards and the 675 Watts is going to save you >$2.50CAD/day ($912/year)

Plus you will save on the cost of the power supplies, not needing as large of wattage nor will you need 2 circuits.  The two 850s will run on a single 20 amp safely

I can power 8 1070s, 8 risers, cpu, mobo, and ssd with two 850w g2 evga?
How should I safely power the risers? Split it all evenly?
I have 6 pin risers coming that come with 6pin - sata adapters.
Power the risers via the sata ports on the psu's?

[millsys]

Yes, you only need a single sata for your SSD (64gb MFC is plenty) if you choose to use an SSD, some just boot off usb flash
The two 850s will each have about 8-12 SATA connectors, plenty to power the risers
CPU/MB/SSD/Risers will use 100-150 watts total

how many risers can I safely connect to one sata port. I heard if you connect too many they will fry the sata connectors.
here are my adapters: https://i.imgur.com/c0rsSEu.jpg
looking at the back of one g2 850w should I do this?:

[millsys]

With the 2 power supplies you will have plenty of sata power for those risers, you can do 3 risers per strand but I would recommend just doing 2 per stand, so use 2 cables off each PS to run 4 risers, and I would even chain the SSD off one of those.  Or if you are like I use 4 (120mm) fans to draw air away from the video cards, using a molex cable strand to power the fans and the SSD (via molex to sata adapter)

[QuintLeo]

G3930 is cheaper by a couple bucks - but has Kaby Lake compatability issues with some motherboards and operating systems.
IMO it's worth the extra couple bucks to get an older Skylake part to avoid the issues.

 You cannot connect ANY risers safely to a SATA port - the actual SATA CONNECTOR is not rated for the 75 RATED WATTS POWER DRAW on the PCI-E bus (the CONNECTOR ITSELF is only rated 54, and some cards DRAW MORE from the PCI-E bus on peaks).
 Since you already have PCI-E risers, I'd recommend getting some MOLEX to PCI-E 6-pin adapters to use on most or all of them as the EVGA 850s aren't going to have any PCI-E connectors to spare.

[millsys]

The graphics cards won't be drawing from the PCIe Riser as long as you have the PCI-E connected directly to the video card.  My rigs run just fine on SATA power connectors directly to the Riser.
6 GTX 1070 + MB + CPU + RAM + SSD = 75 watts idle and 860 watts at full hashing load (cards set to 90% power).  I run that 860 load on a single 1000 watt PS

I would recommend AGAINST those Gigabyte cards - they really went cheap on their fans on everything BUT the Aorus line the last couple-three years.
They work well enough as long as the fans are running though, and decent cooling, but I've had fans go out on *2* of them (1 fan each) in the last month, and the fans are deliberately designed to be a nightmare to try to re-lube (not that re-lubing lasts long in ANY case).

EVGA, MSI are all ball bearing fans (except PERHAPS the MSI blower models, I've not gotten confirmation there either way) - I'm fond of the EVGA SC "black" models for their consistantly good cooling, dual ball bearing fans, low level of fancy "pretty" LED lighting that just wastes money on the card design and construction, and usually low pricing.

Damn the one you are suggesting (08G-P4-5173-KR) is $560 but I can only get 2 at that price. The rest I have to get at $580

What about the 08G-P4-5171-KR EVGA GeForce GTX 1070 GAMING, 8GB GDDR5, ACX 3.0 & Black Edition? I can get that one for $553

[QuintLeo]

If you can get the Gaming for less than the SC, do it.
They're normally MORE expensive.

 Just double-check make sure it doesn't need additional power connectors that the SC doesn't need first.

[Bigdrago]

Did you order and the rig is up and running?

Do you have all psu connected to the motherboard? You were talking about 4 psu, but I thought the mb only needed 3?
Can the gpu draw power from the board or do you need powered risers? On the website it seems like enough to connect psu to mb.
Risers gets power from the psu AND gpu gets power from psu?

I've gone with 8 1070s and 2 850w. They just arrived haven't put them together yet. Can't answer your question yet.
