Aukuoy PCI-e 5.0 16Pin Extension Cable: 12VHPWR PCIE Cable16AWG 600W 90 Degree Female to Male Extension Cable for Graphic Card GPU 12+4pin RTX 3090Ti 4070Ti 4080 4090(Type B)

Absolutely safe solution for a RTX 4090.Been using since July and no sign of overheating or melting.COMPLETELY SAFE!

Aesthetically is not very pleasing but, It’s working, which is what matters. I’ll report back if there are issues. So conservatively 4 stars.

At first everything was working perfectly but about two months after purchasing, the cable started to heat up during a gaming session and started melting. Luckily my pc is on the desk and I was able to immediately turn it off when I noticed the smell and the warping plastic.

I got this to go with my MSI RTX 4080 as my case is really tight and doesn't leave enough room for the default cable to bend at the angles that are recommended. I was annoyed at first, as instead of the cable going down (my mistake, thought it would go down), it goes upwards. This annoyance turned into happiness though, as the cable routes through the back much cleaner than if it went the other way, so a happy mistake on my part!Can recommend this cable, but just note that I think they recommend the A or B type for cases where the PSU is at the top, but in my PC the PSU is at the bottom. Again, I'm actually glad I got the 'wrong' recommended cable as it works in my case way better!
