Can't find fitting psu

[andric.stefan77]

This is the list of other parts that i will use:
Asus 1080 TI (12x)

Mining Rig 12 card Rig Frame

Asrock H110 pro btc+ motherboard (1x)

Intel g4400 CPU

Ram

6 pin to 2x 8 pin PCIE adapters

But i can't find any fitting psus. If you can tell me a couple alternatives. Thanks.

You are going to need 3-4 high wattage power supplies to power that, no single power supply can do 12 GTX 1080 TI's, not a chance.

 

[andric.stefan77]

If it is not a problem for you to send me a couple of examples of witch ones.

Heres a decent summary updated a few days ago

You will also need an adapter to be able to start all 3 power supplies at the same time.
I assume you know roughly what your power draw would be for each GPU? miners often tune the power settings to reduce electrical costs. This information should be available online, with this you can calculate the wattage and # of power supplies needed

Also if you are in north America, say if you need 3x 1200w PSU's, make sure they are plugged into 3 different 120v 15A circuits otherwise you will trip a breaker once you apply a load.

Can also look into server power supplies they can be cheaper but have to be modified to work with multi GPU's

Thank you very much. And if you don't mind to tell me which wallet would be best to use for smOS mining.

 

[Snipergod87]

I have no idea, although storing your funds in an offline wallet is the best choice when it comes to security, nobody wants their hard earned money taken when an exchange gets hacked.

Would this one be fine? Full Modular PC Power Supply For 1600 Watts 90 Plus Gold ETH MINER PSU

Here are the specs:

And do i really need 3 or is 2 enough?

 

[Snipergod87]

At minimum 2 of those for 1600w each, I cannot speak to those units quality or efficiency (if it is really gold rated), a single 1080 Ti is 250w TDP when mining (can be tuned up or down), multiply this by 12 and you get 3000w, with 2x 1.6kW PSU's you have 3.2kW available, will be tight considering you still need to power the motherboard+cpu.

 

[andric.stefan77]

So i can get a weaker psu? Which one would you recommend me and how much watts do you recommend?

 

[Snipergod87]

you really not need that much to run a board+ CPU, 200w or so at most, it would be best not to have that one one of the 1.6kW PSU's (cannot be split between the two) as you will only have 100w left over for the entire system which may not be enough. Its difficult to find good low capacity psu's so you might be looking at something in the 300-450w range, higher efficiency is better but you wont be pulling alot of power out of the smaller unit

 

[andric.stefan77]

Do you have any reccomendations?

 

[Snipergod87]

A SS-300TGW is pretty cheap and gold rated, again I don't know what country you are in, you can look at the Corsair CX (2017 editions), or SeaSonic M12II or S12II models

 

[andric.stefan77]

And also should i connect gpus to 1600w and everything else to 300-450w?

 

[andric.stefan77]

If i buy 2× 1800w of the ones i talked about earlier, will that be enough?

 

[Snipergod87]

Those listed earlier at 1.6kW not 1.8kW, its possible as long as you down tune the 1080 Ti's to a more efficient TDP, this setting will vary on what you are mining and is calculated as hashes per watt. If you did get 2x 1.8kW those would be sufficient.
And yes it would be GPU's to the 1.6kW PSU's and the motherboard to the smaller unit if you go that route, you will need a 24 pin PSU splitter, either a dual PSU splitter or triple if you are going 3x PSU's

 

[andric.stefan77]

Thank you very much for the help.

Do you think this one could do the job for 4-5 gtx 1080 ti?

Brand Name: CLTEIN

Model Number: CL-PSU04-1

Input Voltage: 175-240V

Output Voltage: 12V

Output Power: 1600W

Output Frequency: 47-63Hz

Output Current: 125A

Input Current: 15A/8A

Application: Bitcoin miner PSU

Dimensions: 150*185*85mm

 

[Snipergod87]

Yes, you will need a seperate power supply for the system itself as it looks like it only outputs 12v, and the motherboard and other components need power from the 3.3v and 5v rails as well

 

[andric.stefan77]

Would this one to a good job for that?

Output power: 400w
