Is this enough to support my GPU?

I recently took my PC to a repair shop, and the tech recommended I get a support bracket for my GPU to prevent sagging (I have a Zotac Gaming 4080 Super so its on the heavier end). I purchased one from Amazon (https://www.amazon.com/gp/aw/d/B0BTVJSTZ7?psc=1&ref=ppx_pop_mob_b_asin_title), and I was wondering if this enough to support my GPU. I am a little bit worried as due to the shape of my GPU and where the fans are, that's the best place I could get it. The GPU isn't fulling resting on the top of the support structure, and I am also worried about how the proximity to the fans, I was potentially thinking about buying a second one and placing it on the other side of the GPU, but I don't know if that's overkill, and I'm worrying for nothing lol.
