GPU switching question

in Technical Help (nuts n bolts)

So I'm basically spending all my time in Daz these days, and GPU prices won't be going down anytime soon, so I'm debating making the switch.  My usualy hardware guy isn't an option at the moment, because there's some nasty bug going around, so I'm thinking of swapping out cards myself.

My question is can I just plug a 2080ti into my system using the same power connectors?  My old card is a 1070.  My PSU is some Thermaltake 750W model.

I've attached a text file with my current system details from CPU-ID.

Any caveats would be much appreciated.

    The 1070, or at least the one I have, uses only one power connector. I think the 2080ti might need 2 of them. The 2080 super uses 2 at any rate, I would think a 2080ti would too, but I have been wrong before lol. As long as you have 2 of the 8 pins to use, swapping GPU is relatively easy, just look for a youtube vid if you are unsure, watch a few times. Don't be super scared of hurting the motherboard, they are pretty damn strong lol.

    You're correct - 2080ti also uses 2x8pin connectors.

    For the OP, the nvidia site says:

    1070: Graphics card power: 150W   Minimum System Power Requirement (W): 500

    2080ti: Graphics card power: 250W  System Power Supply Minimum 650 W or greater system power supply with two 8-pin PCI Express supplementary power connectors. 

     

    The following are from guru3d.com:

    GeForce GTX 1070 / 1080 - On your average system the card requires you to have a 450~500 Watts power supply unit. GeForce GTX 1070 / 1080 SLI - On your average system the cards require you to have a 750~850 Watts power supply unit.

    Here is our power supply recommendation: GeForce RTX 2080 - On your average system we recommend a 600 Watt power supply unit. GeForce RTX 2080 Ti - On your average system we recommend a 650 Watt power supply unit. SLI - On your average system we recommend to add 275 Watts on the above values.

     

    If you do decide to upgrade, I would keep the 1070 card somewhere safe, and when funds allow, upgrade the PSU or your pc and put the 1070 back in as a second card.  IN terms of large scenes, it will drop out before the 2080ti but for most scenes you will have the extra cuda cores for rendering.

    As pointed out you need to check if you have a second 8 pin PCIE power connector. I'd be surprised if a recent name brand PSU doesn't have it.

    Your PSU could be modular so you'd need to find the correct cable and plug it into your PSU as well as connecting to the GPU but that is still very easy.

    Thanks.  I guess I'm good to go then.
