Backplate necessary? - do GPUs bend somewhat easily or what?

Henrik Jensen DK · Apr 4, 2014

I'm reading a review of the MSI GTX 780 where it says as a negative that the card has no backplate.

I'm wondering if this will be a big problem? Do such long cards bend somewhat easily?

I certainly don't want to spend $$$ on a graphics card and then see it bend/getting damaged

Thanks!

it's more of a bling thing in the expensive card sector more than anything else, sure it's nice but i doubt it's necessary
i believe the card has a metal "sideplate" if you can call it that that should prevent it from bending (it's the main purpose of it)

It's not just your GPU you can damage. Depending how heavy which mine is. You may damage the Motherboard slot too.

Wait! I'm thinking the plate that hold the card onto the case. If it's just the pretty looking plate around the fans well. I suppose that would be ok. Your' card won't moving around a lot unless your moving the PC around a lot.

I'm not sure if any test were done, but I'd assume that plate was for directing air. Not sure if it affects temps for the good or bad

Backplate shouldn't be necessary for any high end card. The purpose of the backplate is really to improve appearance, and I guess slightly reduce temps (1-3C).

Purpose of backplate is to prevent card warping. This is an issue where high cooler weight and heat come into play. Not all cards need them.

A warped card can cause the cooler mount to loosen, possibly even get a gap between the cooler and GPU die. This will destroy your GPU.

If the card you're looking at isn't very long then warping is not a major issue.

maddogfargo :

Yeah that makes a lot of sense. I haven't considered the fact that heat with expand and contract everything. Good point!

either way .. there's still the metal on the side which does something similar... maybe just not as effective but maybe it's just as good...
