2 Gpu 1 Box

[Economistfirendly]

Hi,

I am planning my build , i have almost everything already , what power supply do i need to handle my 2 RTX 3060 ti? Both being MSI GeForce ventus 3 fans OC.

 

[RollinLower]

is this a workhorse? why do you need 2 GPU's. SLI for games is dead and buried.

RTX 3060 TI doesn't even have SLI so you can't use it with another one...

Even if youre just bitcoin mining and rendering, youll still be better off served with a 3080 in terms of efficiency. So get a 3080 instead, with a 750-850W PSU from reliable brand like Corsair, Superflower, and Seasonic.

This is false , only gamers are concerned with SLI.

I will keep my graphics card and will do as i said.

I am not concerned with SLI , only gamers need sli to use multiple GPUS.

so you're either using them for compute or rendering then. sure, that's a valid reason.

what is the rest of your planned specs? if using a normal intel or AMD ryzen platform you might get away with 750 watts, but if you get something power-hungry like threadripper or other HEDT or server stuff you might want to go for 1000+.

Not false at all. The 3060 Ti does not have SLI support nor does it support NVLink. You can still use two of them, but they can't work "together".

Honest to god stubbornness wont get you nowhere. But hey, im patient girl so let me help ya in.

 

Depending on your setup, you can still go with a multi rail 850W PSUs, but if youre running a more powerful or power greedy CPU like 12900K or a maxxed PBO 5950x, then just go for 1000-1200W for the safe side.

Here is my other parts ( i have all of them ) Ryzen 5700X / 2 ssd nvme / 64GB ram / Dark Rock 4 

 

I just a motherboard (nothing fancy ,  something like a Gigabyte B550 AORUS ELITE V2 maybe ? ) a power supply and a case ( i can get a MSI MPG GUNGIR 100P for very cheap )

Well you never said you weren't gaming, yes for mining they can be used together

We do not all live in united state of america where it's raining GPU super cheap, we have the gpu that we get ,if we are lucky enough if we do  not need to wait months to even have a chance to get something and that's it.

This is false , my program can handle up to 4 gpu all togethers just fine thank you , and do not need sli , crossfire , nvlink or anything like this , they just need to be plugged to my computer. I said it twice and will say it again , all the stuff you named are a gamer's problem only.

I know perfectly well software can use multiple GPUs. Nobody is denying you can use all your GPUs either. If your software can leverage multiple GPUs, more power to you. They just can't work together in the SLI/NVLink sense, which in a context as this forum would be the most likely use of a multi-GPU setup. That is all that was pointed out.

You did not specify the context in which you wanted to use two GPUs, hence for the context of this forum, you got the natural advice that if you were planning on buying two for gaming, cards nowadays can't work together anymore in that context.

 

In regard to working together, yes, software for a GPU-suitable workload can still send its jobs to however many GPUs the system has to have them each work on their own piece of the task if you've written code that can utilise multiple GPUs. NVLink, for example, allows pooling of VRAM and high-speed communication between each unit, and since the 3060 Ti doesn't support NVLink, they can't work together in that sense.

 

As for the PSU, Nvidia recommends a 600 W one for a 3060 Ti. With a listed 200 W TDP I'd opt for at least an 850 W unit for a dual GPU system then.

If i needed advices on how to use my gpus i would have created a Topic on the matter.

OP, let's bring the heat down on this conversation. GPUs are not cheap in the US. Or anything else for that matter. Don't make bias based attacks towards other members.

Secondly, had you filled out the outline provided at topic creation, this topic would have gone more in the direction needed to help you instead of members needing to guess and assume.

 

For everyone else, let stop arguing about how the OP is using the GPUs are if they will work together.  This topic has derailed from the original  question asked.

This forum is not natural a gamer forum, it's a TECH forum and all kinds of experience level questions are asked.The biggest problem is people jumping to a conclusion and assuming one thing over another. 

 

Now back on topic.

That's fine, but this is genearlly a general tech (though this is just as much tech as anything else) and often gaming oriented, some productivity, forum, so that'll be an assumption (for better or worse). If you come in with a specialised multi-GPU use case, it takes 5 more seconds to say that you are not planning on using them for gaming or the more well-known multi-GPU options such as SLI, and no effort to mention that in a friendlier way than the almost arrogant/condescending replies earlier.

 

In any case, I'm not going to drag this on further. I've edited my reply with that I think you should go for an 850 W unit at least. Maybe go for a 1000 W one just to be safe in terms of CPU load and Ampere's spikes in power/current draw.
