Suggest me safe power supply for 3 gtx 1070ti 24/7mining

[trog100]

Yeah, admittedly I stopped at the appalling 1kW suggestion and scrolled up a bit from the bottom, LOL!

a 1070TI will stand a max power setting of 60% without losing hash rate when used for mining.. so that 180 watts is well out which makes the 1000 watts suggestions even more daft..

whoops i forgot i said i was out of this thread.. he he

For what it's worth, I was running 2 x EVGA 1070 and it held steady at 385w total. Did some testing with one card, then the other, and each were running under 150w. They remaining system (which was not designed to be energy efficient, just happened to have it on hand) was pulling under 100w. 600w PSU should be fine for 3 x 1070 cards.

So which is it ? Title ans post say 2 different things .....

Power 3 1070 Tis

or \

Adding three 1070s ... adding them to what ?

If we go by NVidia''s public specs:

https://www.nvidia.com/en-us/geforce/products/10series/geforce-gtx-1070-ti/

Thermal and Power Specs:

Maximum GPU Temperature (in C) = 94
WGraphics Card Power (W) = 180
Recommended System Power (W) = 500
Supplementary Power Connectors = 8 pin

You'll need 500 for the system and 1st card + 2 x 180 watts or 860. If anything is overclocked, that will drive wattage up.

Looking at the EVGA model tested by TPU, it peaked at 204 watts in gaming and 210 watts under zFurmark ... MSI Afterburner allows up to an increase on the power limit when overclocking so if going that route ... you have a theretical 280 watts max per card (840 watts for the cards alone) , or 100 watts additional per card... or 1060 ***theoretical*** overclocked and gaming. Mining shouldn't bring you anywhere near that ... Id want an 850 (for up to 675 watts of real load). I use the common rule of thumb of 1.25 times max power draw for light - medium duty and 1.5 times fpor serious overclocking / gaming boxes

However, might be worth considering that PSUs are most effecient at 50% power, so you don't want to be mining 24/7 if your are in countries with high electric rates.. In India, reported average electric cost was $0.08 per kw hr in 2017 which is pretty good .... in some areas of Inbdia tho, it's double that..... Let's do worse case @ $0.16 which still isn't so bad.

Let's examine two scenarios

0.600 kilowatts x 24 hours x 365 days x 3 years x $0.16 = $2,523 at 100% effieciency

650 watt Platinum PSU w/ 600 watt load ... (90.5% efficient)
At 90.5& efficiency this cost is $2,787.71

1050 watt Platinum PSU w/ 600 watt load ... (93.5% efficient)
At 93.5& efficiency this cost is $2,698.27

So the savings is about $90 for getting the bigger, quieter PSU.

In short, if you can pay $90 more for a 1050 watter, it works .. pay now for the more expensive PSU or pay later to the electric comapany . If ya lived in Germany where average cost is double that, buying the bigger PSU makes sense . It will also run quieter, have loads of headroom which should deliver longer life as well as provide plenty of room for future expansion. I'd do a 850, but a 650 w/ three 8 pin power cables would work

A Seasonic X650 Gold has (4) 6+ 2 Pins
EVGA 650 P2 has (2) 8-pins and (2) 6+2 pins
A Corsair CX650M w/ (2) 6+2 pins just isn't gonna cut it

Obviously the bigger PSUs in these series will be capable of doing the job but more efficiently, quieter and at lower electric cost ... You will have to run your own numbers to see if that costs offsets the difference in purchase price.

I don't know why we are playing a game of theory. How about this he could run 4 of those on a 850w as long as it was a good psu. When setup for mining it wouldn't pull more than 550w at the wall. There is no reason on earth to go with anything higher than something like a 750 supernova.

Those of you arguing efficiency. Find me the ROI on doubling the cost of my PSU at a loss of 4% efficiency. That is the difference between 50 and 100% load on most higher end units. Some are as low as 2%.

This isn't a gaming rig, this isn't a furmark rig. This will be doing mining, these cards if setup correctly will never reach the tdp levels you see in games let alone furmark.

Should be fine for 3-4 1070's. Good choice.

Only 3 4 ?

 

[silkstone]

Only 3 4 ?

That's how many you have, right?
If you want to add more, you can likely get the 1070's down to around 150 W each and run 6 of them.

oh thank god, i thought psu of bad quality. its hard earnt money i spent xD
for more 2 - 3 gpus.

As you have Bought localy ( good for that unwanted and unexpected failure as rma would be eaysier not that i expect or predict any failure).
lots of people have said /stated you don't need such a High wattage PSU and they are right (BUT)
since you have Started mining ( and i do read and follow your posts/threads) you have expanded your operation
and no doubt will continue to add to your mining Operation.
what you have wisely done is to give yourself some spare future power capacity for further expansion

actually i was going for small like people suggested in thread, but small were out of stocks, i could buy from online but, i dont buy senstive things from online, because my local shop person is good friend and actually biggest shop in city, he handling lot of service centers like msi,asus,zotac service centers and thermaltake too. it is going much easier for me to replace (if needed, like he always do)
as you know crypto crysis on hardware, he only had few 700w and 600w of various brand but in bronze model,
at that time i was going to ask in this thread,for should i buy 80+ bronze or not, then i thought it would not good to ask small things again and again,
then i bought 1000w with keeping in mind that will help in 2 3 gpu also..
(sorry for english mistakes,fast typing)

--------------------------------------------------------------------------------

one thing i wanted to ask, i have less pcie wirte about (6)
are all modular psu wires same? (80+ gold)
i wanted to have one more PCIE 8pin, i tried to search online they are selling full kit costs 150+$ but i only need pcie power cables.

I use Seasonic Prime Titanium 850w/1000w exclusively on my rigs. They're basically the best readily available consumer PSU on the market. The new Prime Ultra series are a minor upgrade across the board.

You could run 6 1070's on that unit fine.

 

[yotano211]

You could run 6 1070's on that unit fine.

I run 2 1080ti and 4 1080s on a 1000w unit, all throttled to 65%.

 

[cdawall]

I run 2 1080ti and 4 1080s on a 1000w unit, all throttled to 65%.

I normally assume closer to 75-80% power which on a 1070ti should be right around 130-140w per card. That puts it right around 840w in just GPU leaves plenty of room for whatever weird load spike might hit and if he wants to push up to 100% TDP with an overclock the room is there. Never know what coin might go to the moon.

I do more of a mining efficient vs mining speed. That and some breakers in my apartment wont do 70 or 75% TDP.
