AMD RX 480 Fails PCI-E Specification

Only one person has claimed that it's damaged his motherboard. Although his system was very old, and in a terrible state.

Isn't this what the Auxiliary pci-e power connector that you get on all sli/crossfire boards is for? To cover instances where more than the standard 75w is called upon. Even though I only usually use single cards, I still connect the molex or sata cable to provide the extra power for extra stability.

It's to aid power distribution when 4 cards are each drawing up to 75W which would be the board delivering 300W to the slots.
 
After reaching 92 Celsius on Firestrike benchmark and the driver crashing while browsing facebook/youtube I give up with this card. Terrible cooler, and a terrible package at stock. Arranged to go back tomorrow!

Wanted to give AMD a chance, but not ever buying their reference design ever again. :mad:

Not even including the debated PCI-E issue which troubled me slightly anyway (albeit I don't have an el-cheapo motherboard).

Wonder how good or bad their custom cooled versions will be...

750ti for a start, there was more but im not too bothered looking for it now. I think it was a 6600gt or something and a few others.

The 750ti through the socket doesn't exceed 66 watt - you might see certain sites showing a slightly higher number but that is because they are measuring the power delta at the wall and that figure includes any power conversion inefficiencies. (So the card "consumes" ~80 watt at the wall but only 50-66watt max at the socket).

I'm not saying there isn't an nVidia card that actually does exceed the spec at the socket - but so far every card suggested has been shown to be comfortably in spec with most only around 30-35 watt actual.

My favourite was the 6990, people really thought there was nothing wrong comparing a top-end dual part to a low-mid finfet one.

They must have gone through every review in the past 10 years looking for overall power consumption figures. :D

Custom ones are usually significantly better. Look at the 290X reference, it ran at an average of 90 degrees plus. Then in comes Sapphire with their Tri-X Nitro cooler, and suddenly the card is overclocked a decent amount, and maxes temps under heavy benchmark loops at 72 degrees.

I'm positive the 480 Nitro card from Sapphire is out to be fantastic, given it's Heatsink is 3-4x the size of the reference one alone. Plus a custom PCB with better power management as well.

The reference cards have also had their prices jacked up, so the Nitro card is currently £10 more as well.

Shame AMD even bothered with a reference card really, their board partners have fantastic designs.

Am i missing something? Doesnt that show it pulling MORE watts through the pcie express slot?

68W from the PCIe Slot vs 82W previously.

Blue and Green are the new Driver, green being the new Compatibility version that lowers power use even further.

More power is now drawn from the PCIe Connector.

Mainboard is the one you want to look at, both 12V and 3.3V

Now we just need to see the performance impact from the new "Compatibility mode", although they also said they gained up to 3% extra performance with the new drivers, so it should offset anything.
