didn't know about the nvidia-smi tool till now

I set in Afterburner the power limit to 100% and you will not believe what nvidia-smi showed as Power Cap >>> 230W Shocked

btw. Power Limit at 65% shows a Power Cap of 149W - so this is the official consumption of the GPU Cheesy

230. On a GTX 1070.

Ouch.

No WONDER they thought they needed the extra connector. They DO.

That's more than any of my GTX 1080s use (they're Gigabytes with a high factory OC and a "raised" 200 watt TDP).

I just do not understand why, i mean you can OC and under-voltage at the same time very good with it, till now i didn't get it over 192W with high OC settings and still under-voltage while mining i think ZEC where he uses Core + Memory at max.

I get the MH/s or S/s top rates from other 1070 cards often with ~ 150W usage, right now i mine UBQ with 30.5 MH/s at 150W (0.975v) and just get 55°C on the card (it's very hot here so my flat is +28°C Cheesy

As per the MSI Website the Power Consumption is 150W

What is the TDP displayed in nvidia-smi when you set the card to 100% in Afterburner (or whatever you use)?

I don't see the point of 2 power connections on a 150 watt card - I bet the REAL figure is at least 180 and possibly 200.

I hard modded 6 MSI 1070 to run @ 0.65v to mine ETH at 30Mh/s. They consume 104 watt each from the wall. (stock was about 165 watt)
I run the total system with a 850 watt seasonic platinum no problems.
Without the hardmod you can set the powerlimit to 100watt. That will get you to about 120watt each a card from the wall so you can run it with a 850watt supply as well.

if you do dual mining 1000 would be not sufficient unless you reduce more the tdp, but i remember i tested it with a 1000 and was doing 300mh on decred and 28 on ETH, which is good for me

How about the on the wall power consumption?

With the EVGA 1300W you might run into the issue that you have only 2 x 8+8(6+2) and 4 x 8 connector, some 1070 GPU's need 6+8 connected to power on

Not even my Gigawatt GTX 1080 models with the 180 watt TDP need 2 connectors - and since the PCI-E spec states 75 watts from the bus + 150 watts from a 8-pin connector, I'd really like to know why anyone would put 2 connectors on ANY GTX 1070. That would be a 50% increase over the "base" TDP the GTX 1070 was designed for after all.

GTX 1080 I could see it for a card with a very high factory overclock perhaps (but I've not SEEN such a card to date), and the base GTX 1080ti needs 2.

The cabling on the EVGA G2 1300 is heavy-duty enough you could pick up an extra cable set and use dual-connector cables in all 6 of the "VGA" ports on the PS safely.
I don't know offhand if Seasonic sells extra cables, but EVGA has them listed on their website or forums somewhere (but they only sell "complete" cable sets, not individual cables).

I have an MSI GTX 1070 Gaming Z and it requires an 8 pin + 6 pin.

What is the default TDP on those cards?
That power connection setup seems WAY overkill for a 1070.
(Not disbelieving it exists, since 2 of you posted enough reference info I could look it up on MSI's page).

https://www.evga.com/products/productlist.aspx?type=10&family=Power+Supplies&chipset=Power+Supply+Cable+Set+(Individually+Sleeved)

Might be cheaper to grab a pair of the "$29.95" cable sets from that page, they have 2 of the dual 6+2 cables in each set.

I am mining ZEC using EWBF with 65% TDP and it is drawing 145-150W. Gets 480 sols and sits around 47-48 degrees.

As per my power metering between PC and Power Plug it was already at ~ 180W and this was also shown by EWBF, i was at ~ 75% power limit at this time Wink

- right now i have 65% power limit configured and EWBF shows ~ 150W for the GPU.

If you like i can also send you a photo of the error message when you try to boot computer with just 8-pin connector plugged in

Try to boot a computer with MSI GTX 1070 Gaming X 8gb card with just 8 pin connector and you get an error "please plug in pcie power connector" (or something like this) - there was no option to confirm that error, with the 6-pin port in addition connected you couldn't boot.

Sent a inquiry to EVGA and they confirmed they can send the 8-pin PSU > dual 8/6+2 pin cables from their RMA stock after you register your PSU on their website (and not just the bundle with all cables) - price might be ~ € 20-25 per cable (and you need 4 of them as there are just 2 in the box).

yeah a 1200 will do it, either supernova or corsair 1200 platinum are good, but you can also try to buy 1 rm1000i, will do good if you lower the tdp to 80%, and it's less expensive than the other 1200watt psu

If you mine ZEC, 1200W is enough.

i think it's enough for every algo, maybe not for dual mining with clymore, but you can always underclock and undervolt, to make it enough anyway, i like to run my gpu at 80% for this reason

using Molex / SATA to 6 or 8 pin connectors might cause a lack in Molex / SATA connectors for the PCIe Riser Cards (where you need 6 of them too).

The Cooler Master v1200 Platinum has 12 x 6+2 Connectors so it's possible to connect 6 x 1070 GPU's with 8+6 using all 12 connectors you have.

I like the 1700w psu because I can run 7 cards now and maybe more in the future. PSU can last more than a decade if they're good, worthwhile investments.

Stick with 1200W power supply, preferably Corsair/EVGA (good price/performance ratio). It isnt a good idea to run at almost maximum load PSU especially for 24/7 operation.

1070 cards have a 150 watts TDP , so for 6 cards + your system need min 150wx6= 900 watts + around 100 watts for ur cpu/mobo/hdd/mem , so your total system draw going to be around 1000 watts , if you know how to overclock and the same time undervolt your cards you will be ok with 1200 watts psu . I would not use 1000watts psu for ur setup...
Building mining rig to about 80-85 percent of a PSU's capacity is advisable to achieve maximum efficiency and stability .

Some GTX 1070 cards have as high as a 180 watt TDP.

(edit) if that's the MSI 1070 model with an 8-pin AND a 6-pin the TDP appears to be 230 watts, per discussion in another thread.

I'd recommend going with a good-quality 1200 Watt or higher - EVGA G2 1300 or Seasonic X-1250 gold would both be good choices.

Platinum and Titanium are more efficient, but the MUCH higher cost tends to take too long to pay off unless your electric cost is VERY high (and in that case you're probably not going to be very profitable in any case).

thesavoyard what trademark has 1700w? Undecided

im curious

Lepa has a platinum rated 1700w psu, they are rock solid but rare and mostly used. Enermax Platimax 1700w is new but the wait is 2-5 weeks, haven't received that one yet. It will be powering my 7 gpu rig most likely.
