hi, I have evga 780 ti classified and it comes without back plate there are few modders that are making back plates made up of acrylic my question is are they strong enough to withstand higher temps like upto 90C? and what way would be safer to stick back plate to pcb, either the magnets on the 4 screws of pcb or double sided tape?
IS THERE ANY ONE WHO HAVE USED ACRYLIC BACK PLATES IF YES COULD YOU SHARE YOUR EXPERIANCE? :(
 
Back plate would get no where 90'c as its not touching the core.

As much as i think back plates are pointless i think acrylic would be more than fine. If your really worried just stand it off a little from anything on the back of the card.
 
I had custom acrylic backplates on my 290Xs, which I've now transferred to my 390s. Core gets a little warmer than I'd like (AiO cooled), but generally fine with these ludicrously hot GPUs.

how did you manage to stick the back plate to your gpu's pcb?

you serious mate? back plate can prevent the pcb from getting dusty you know how its risky and hard to clean dust from a pcb? in case of back plate just swipe it with cloth, and it looks good from the case window.
 
Rap_kasper5, if you hit the quote button on the bottom right of sumones post it will quote it for you so you dont have to copy paste it.

Backplates are mainly for looks rather than dust prevention, if your struggling to remove dust just grab a can of compressed air and it will blast straight off with no risk at all.
 
The melting point of acrylic is 160c according to google, so it's absolutely fine unless of course your card is on fire. The PCB should get nowhere near that hot during normal use.

I was reading thermal properties of acrylic and what I have seen is they will start to get brittle if exposed to 90C for long time but I think this max temp can be change for different acrylic with different composites, by the way I got my answer I am sure its safe to use them as the guy BONJOUR have already confirmed that they are safe and he is using those back plates without any issue :)

it would be hard for me to find those screws do you recommend very little double adhesive tape on those four gpu socket screws?

I'm not sure I'd recommend adhesive tape. You want a little space between the backplate and the card. The plastic washers I used were about 2mm deep.
