[Reddit] RX 480 fails PCI-E specification - Page 5  

post #41 of 1129
I'm going to fall back on my conspiracy theory: pc class rx 480's are gpus that didn't make the cut for next gen consoles. Hence why we're seeing so many issues and high initial availability.

Link?

Everyone knows the 480 was a space heater, but I can't find anything about it pulling way too much power over the Pcie bus, specifically.


The other thing is that the RX 480 technically isn't a top end card, unlike the GTX 480 or the dual GPU monsters. People dont expect it to go way over spec.

EDIT: spelling

I meant more in the sense that it drew a lot of power altogether. Iirc it drew as as two 5870s which was it's competitor at the time. We also have to remember these are reviewer cards and may not be exactly what is released.

My Sapphire RX 480 8GB arrives tomorrow and I'm excited, but I'd be lying if I wasn't a little worried about this issue. Hopefully this issue blows over in the next couple days otherwise I might be convinced to return it. On the other hand if I could accurately test my power draw and make sure it's safe I will definitely keep the card. What tool would I need to test it?

The original comment was me saying that a cheap psu could have issues with delivering more than 75w through the 6pin. Cheap supplies have cheap cables, cheap cables pushing 100+ watts through them when rated for 75 watts = no bueno

Cheaper the card the more in line with spec it should be as the consumer will likely have a less than optimal psu

You're not supposed to do that. Do you understand?

So what if you can draw more than the spec? So what if nothing happens if you do so?

And no, any PSU worth its salt would totally flip once any single connector is over its spec. Protections and all that to prevent house fires from people like you.

The naming scheme here is bonkers. As someone that hasn't followed gpu releases closely the last few years, I can at least ballpark it about what the nvidia cards are in terms of release. With amd, you've got the 5000 series to the 7000. Then this 2xx to now 4xx. Give amd (which should have kept the ati name for the gpu division) a good marketing team and get rid of the team they currently have.

Yeah no my PSU has OCP, and it doesn't trip the second power draw goes over rated specs. Christ if a PSU tripped OCP the second it went over rated specs without allowing for at least some tolerance, then that's just bad design.

Tolerance is in the specs.

For example breakers can witstand an overcurrent for the amount of time the spec specifies. (Specially useful for motor starts and such)
