Second 1080TI

[glorybound]

2 2080ti with vlink would cost around $2500. Would this be a good investment? My current interior fit fine into my single 1080ti, which is about the same size as all my interiors, so does a second 1080ti make more sense for now? I’m seeing some used 1080ti’s for $600.

1080Ti is a solid card, 2080Ti is even better (speed wise) and plus you get the NVLink.
That being said, it is up to you to decide if you'll benefit more on spending 600 now or 3k later.
Personally i have a bunch of 1080Ti and I'm very pleased with the result.
The only reason i would upgrade is speed, not memory.
So if you're gonna benefit from the speed and you're ok with 10gb of memory, it will half your render time and probably double your income (with a $600 investment).

Your previous question now...
If you can't borrow a 1080Ti to see if it fits, unplug the one u have and try it to the bottom slot.
Make sure you wont need to diy any of the cables down there.
Now, beside space, make sure you have enough power coming from your PSU and GOOD AIR FLOW (both VERY IMPORTANT)!

PS. Aim for a Founders Edition and not the same one, cause temps are gonna be so high even with custom fan speeds. Be really careful when it comes to Airflow, it looks like a small case and it's gonna get hot in there.

As it is, I can’t put the case cover on, so airflow isn’t a problem. I know I can move the 1080TI down, but I am not sure both cards will fit side-by-side. I am not sure what my power supply is, so I might need to find that out. The DELL guy said that if it boots with two cards then there is enough power, I had two cards, but not two 1080TI’s. Is an external GPU box do able?

Get yourself an Asus Turbo 1080Ti and stick in the location of your EVGA, then move the EVGA down. Reason being the Asus Turbo is the blower style fan, meaning only 1 fan, blowing the air out the back. Because the 2 cards are side by side, there's nowhere for the hot air to go on the top card, so it needs to blow out the back.

I wouldnt buy any 2nd hand GPU, because it may have been running 24/7 for mining, and I dont want that since it's life expectancy will be infinitely less

Or even better get yourself 2 X Asus Turbo RTX 2080Ti's, just make sure your PSU will handle 2 cards

Like others have said, you can test if another one will fit by just pluggin your existing one into the slot 1 down (the black one). The cable headers at the bottom might get squashed a bit, be careful!



I have a similar setup as you (with same carpet and table even), and in "mine" it seems to fit

[idnok]

Morne You must be kidding! Are you guys in the same office??
btw..what temps are you having?

[glorybound]

Those are the same price as the 1080ti’s. You think they’ll both fit?

Someone earlier said I would need a new MB for the 2080TI

Hey Bobby,
You can fit 2x 2080tis in your Mobo without issues
You can fit 2 cards directly on your Mobo, you will need blower style cards for this to have good thermals
But in your case, you already have a triple fan design, 3rd party card, so placing two cards next to each other, they will be very loud and they will throttle
To overcome this, buy 2 riser cables(preferably shielded X16 risers, 50CM should be more than enough) let me know if you a link to the ones I use
This way you can place your cards on your desk/floor and they won't throttle
See here,

5 1080tis, idle temps= 30 degrees.. Load temps=55 degrees





You will need to have one more 8 pin cable for the second card(if you will add a 1080ti), and your PSU should be +900W
For 2x2080tis you will need 4x8 pin cables, if you don't have enough Wattage/8 pin cables there is a workaround, let me know

[glorybound]

So, I'll see if I have another 8pin power hanging out in there and if my power is at least 900W, it might be as a simple as purchasing another 1080ti. A worst-case scenario is I have to buy a beefier PS. The second scenario is a beefier PS and 2-2080ti's. The riser cards are just the extensions, correct? Without those will I need two blower style cards, regardless?

Correct, you will need to make sure that the new 1080Ti is blower style and you will install it in the top slot, so you can achieve the best cooling for both cards..
Worst case scenario, If you cannot find blower style(Asus Turbo/Gigabyte Turbo/Founder edition) you can get a similar card to what you have now(it is FTW3 I think)
just make sure that the new card is dual-slot because many of the 1080tis are 2.5 or 3-slots.. (feel free to ask here before you buy if you are not sure)
Your cards will be loud, and one of them might throttle a little which you can live with..
You PSU will have wattage info written on it, or you can check with HP/Dell

A worst-case scenario is I have to buy a beefier PS. The second scenario is a beefier PS and 2-2080ti's

Correct, BUT you don't really need to replace your current PSU, you can buy a new one like 1000 Watts and use it externally for your GPUs
This is possible in 2 ways, first is using a 24 pin splitter cable (your external PSU won't start unless the 24 Pin is plugged into board, this is what the splitter does)
another way of forcing your external PSU to work is using a paper clip, a metal one, you will connect 2 specific pins with the clip(I can tell you exactly how to do this, it is very simple)
BTW, this is what is going on the setup I posted above, the internal PSU is 1k Watts and the external one is 1200 Watts, using the paper clip on the 24 pin cable to get the external power to startup...

The riser cards are just the extensions, correct? Without those will I need two blower style cards, regardless?

A riser extension cable will connect your card to a PCIe slot, it should be around 20-60 Euros depending on if it is shielded and how long it is..
These risers usually solve all thermal throttling issues as you can mount your cards outside your case with plenty of space between them(they will give you the same speed as if your cards are placed directly to the Mobo).. so you don't need blower style cards and you don't need Dual-slot cards
Without these, you better get yourslef blower style cards, but worst case scenario like what I said above, you can use none-blower cards(they will be louder and one of the cards will throttle as it doesn't have access to cool air)

And again for 2x 2080tis you need 4x 8pin cables.. for 2x1080tis you will need 2x 8pin(only one as you already have one card installed)
Let me know if you have any questions..

[Muhammed_Hamed]

Louder cards, because the fans will be running at 70% and higher.. GPU fans are very very loud, jet engine style
Shielded risers mean you will get the exact same bandwidth out of your PCIe slot(the cables are isolated carefully against any external factors), they are a bit more expensive but they are worth the extra money.. like the ones you see in the build I posted.

[glorybound]

Okay. Second 1080ti with riser and hopefully not a new power supply. It's a start. Thanks!

[Muhammed_Hamed]

Let me know if you need help with somethings
These are the risers I use,
https://www.digikey.com/product-deta...IzQeC954iVSYYg
They are the best in the industry really..
Having the cards outside the case, Max temps will be below 60 and they will be very quite, you can overclock them if you want
And you can add more cards to this setup later(up to 3 more cards), let me know if you want more info..Shouldn't be hard to do and you can have all the cards in an external rack next to your case

[glorybound]

Can I have a separate power supply? I am afraid DELL will hit me hard for a new PS, since the case is unique.

[glorybound]

Where things get really confusing is all the choices for basically, what seems to all being the same thing. Also, 1080ti and 2080ti seem to be the same price, so why wouldn't I go with the 2080ti?
