Gtx 1080 LSI what is needed

[traumaonpc]

I want to put two MSI Armor Geforce GTX 1080 8G OC graphic cards into one single pc making it LSI connected with a GeForce GTX SLI HB Bridge, 2-Slot which would be hooked up to a 240Hz Alienware monitor with two other monitors ASUS 144hz monitor & BenQ 60Hz, I would like to know what Power supply, what fan, and anything else that I would need for my computer to run this and not just break. Appreciate the help!

This is my PC and it’s link THANKS AGAIN!

Not sure what LSI is, but you you mean SLI? and as for that P.C......Wow, they wanted $2k for that?!?!

First thing you need is to find out what motherboard is being used and whether or not it actually supports SLI.

YES I meant SLI I wrote it at 4AM lmao. I payed 1,200$ from a Black Friday sale.

I have a Z270-A-PRO or https://www.msi.com/Motherboard/Z270-A-PRO.html , idk if you can tell just by hearing the name but does it support it?

• 2 x PCIe 3.0 x16 slots (support x16/x4 mode)

No. Your motherboard does not support SLI; only AMD's Crossfire. In order to support SLI, you need to be able to run both PCI-Ex16 slots at a minimum x8. Your motherboard can only run the second PCI-Ex16 slot at x4.

So, what is my best solution here? Should i get a new motherboard or should i just purchase the AMD Crossfire SLI BRIDGE? Can you link me the crossfire, i tried to find it but all that pop up is 6$ ones. Pretty sure i am looking at the wrong thing here.

I believe that crossfire bridges come with crossfire capable graphic cards (AMD only) and only if required.

To be honest, I've never been a fan of multi-GPU setups, so I'd just stick with your current motherboard and a single GTX 1080. However, if you're dead set on either an SLI or Crossfire set up, then here's what you'll need to do.

SLI - New motherboard. Make sure it has multiple PCI-Ex16 slots and supports SLI (two PCI-Ex16 slots at x8/x8). You'll then need to get two high-end NVidia Geforce Graphic cards like the GTX 1080.

Crossfire - You can use your current motherboard and you'll need to get two high-end AMD Radeon graphic cards like the Radeon RX-580. The problem here is that not all high-end AMD cards support Crossfire. You will need to verify from the specifications that Crossfire support is listed.

As for power requirements for either solution, take the recommended power requirement for one card (typically around 550-750 watts) and add 300 watts for the second card. That will give you plenty of power overhead.

To be honest this seems like my best option since i already did order my bridge SLI item. Which motherboard do you recommend i use based on my setup. I have about a 500$-1000$ price gap but i am not rying to over over kill it.

Thank you so much for the fast response!

Take a look through these motherboards (PC Part Picker List)

You'll need to find one that has the correct spacing to fit your SLI bridge.

what do you think about the Asus STRIX Z270-E GAMING ?

 

[Wolfshadw]

Probably a good board, but not compatible with the 2 Slot Spaceng SLI Bridge. According to the image I posted, there needs to be three expansion slots between the PCI-Ex16 slots.

ah i see i am very confused since i don't really know much about graphics card i just go by price, i know the basics.
But uh i'll take a look and see what i could do
