Radeon RX 480 "Polaris" Launched at $199

The real question we should be asking is What other cards exceed this spec? and why is it only now being brought to light on an AMD card? if its true Nvidias 750ti does the same thing, and other cards why has it been a non issue until now?

If your going to fling mud at one side, you better damn well make sure the other side is teflon coated or your going to look awfully stupid.

Not the same, try reading up on it.

I think the difference is that the 480 does it even without overclocking (if I've understood correctly). So basically it's not something that the user 'opts in' for. It runs like that out of the box. (I may be quite wrong on this).

It's not a threat and I wasn't trying to shut you up. Telling someone it's not an issue just because someone uses a cherry picked, couple of hundred quid worth of motherboard that has beefed up power phases to overclock for a few days rather than consistently overpowering the PCI-E slot 24/7 on an 80 quid board that there isn't an issue when you can't know for sure is a bit disingenuous.

ASUS can't know for sure how MSI, Gigabyte, etc.. build their cheap boards. If you are that confident will you cover the out of warranty motherboard I have if a card I bought from you that you say is fine, kills it?

Asus followed Gigabyte and are using 2-3 oz copper PCBs which means their traces, etc. are able to withstand higher current than the 480 draws - infact within normal temperature targets they are likely able to operate within acceptable limits at twice the current the 480 pulls. Most of their boards are specced with the assumption that atleast 2x PCI-e 16x sockets might be spun up at high power draw as well so atleast as far as the motherboard goes there shouldn't be any issues there - doesn't rule out any potential issues in terms of the card itself but I don't know enough about that to know how well AMD has designed the PCB to withstand the current draw. There may be some budget Asus boards that aren't specced for the power draw of a pair of overclocked cards in crossfire though.

I have Gigabyte H87M-HD3 board, am I 'safe'?

So your telling me in the history of GPU's this is the only card to over draw power from the PCIE slot? no other cards do this, or have done this, in the same manner?

AMD see it as a problem with a driver fix on the way. Occasional spikes over the PCI-E power limit are fine like with the 750ti, the 480 is consistently drawing above it and some say this can degrade mobo components over time.
 
Some people on this forum have a serious hard on for AMD, and it more of the usual suspects trying to make AMD look bad and damage their image.

On a fundamental level I bet most, as in 99% of people, don't know, including me, what they are really talking about.. I mean really know transistor theory and electronic engineering - just regurgitating what they have read and then add their little piece to it like chinese whispers..

It's all a bit sad. Worrying about what may happen to your board in the future, what damage it may have done is useless. Every time you turn on your computer you damage it, every time you use your computer you damage it, every time you turn it off you damage it - Every thing you do with a computer damages it over time, even leaving it off.

Get over it.

All well and good ultra durable extra copper n all that
but the weak points is the motherboard power connector and the pins in the pci to the cards pci pins if it is an issue at all....

MB connector plug max draw is rated @ 5.5 amps rx 480 power draw coming from MB connector is over 7 amps this is all direct current i suspect the 5.5 amps for the connectors is under spec for head room hence we would see a lot more issues but still not right...

If anything what we would see more of is pc's just shutting down with the 480 as the protection circuits would kick in .... maybe they are and not seeing peeps on line who knows....now just think if there was no circuit protection in the psu or mB then well

take AC example ....if i have an appliance that pulls 11.5 amps but i use a 10 amp fuse in the plug then the fuse most likely going to blow ...now if i use a bit of foil that will not blow then my main fuse box fuse will blow ...now if i foiled the main fuse box so it would not blow then well most likely my house will burn down .....

Will see what the driver fix brings

Just hope my house does not burn down in the meantime

As you admit you are also not an expert in these areas, how on earth are you trying to claim that there is no actual issue here? We've had people with reports of failed motherboards using it, so there may well be something to it. Certainly some tech sites that do have experts believe there could be something to it.

I dont think you realize how hypocritical your comment was. And the persecution complex whining is just all too typical.

Whos to say these motherboards wouldn't have failed not using it? Mobos will still fail...

I watched a report that said nearly every card has spike on the PCI socket above the 75 watts. Some much more than the 480. I dont think this is an issue.
 
My understanding of the whole thing, is that most modern components should cope just fine, but with the RX480 drawing up to 7 Amps over the 12V line that has a 5.5 Amp specification limit, there is a chance that damage could happen.

Turning to the people that say there isn't an issue, if that is the case why are AMD issuing a software fix. If there was no issue they would say as much.

Sure. You can make the same argument about PC's failing after updating to Nvidia's new drivers and all the scares that have gone on with that. When dealing with 1000's and 1000's of users, there's bound to be the odd coincidental failure where people mistake cause and effect.

But that doesn't automatically mean there is no issue, either. Cuz there very well might be and that's why certain tech sites are digging deep to analyze the problem and its consequences.

Fair point - did actually mention that in another thread but overlooked it a bit here - the pins are (should be) better specced for current than the traces (on bog standard PCB) and other interconnects though.

I'm more concerned about the contacts and traces on the actual GPU as I don't know the details on those.
 
the pins on the pcie do not need to be rated much more than the stated 75w..because that's what the manufacturer of the item that is plugged into the pcie has agreed to stick to..those are the pcie rules.

if you go above 75 watts you are breaking those rules..its that simple.

its no good saying oh well he/she drew more than that so I can..no you cant,if you don't want to obey the pcie rules then don't make a pcie card,i think the problem is there is no policing of these rules?

Yes i saw that in the other thread and did post with you on that subject i am sure i did
i do agree with you Roff and good points you have made ...at the end of the day this should not be the way it is re this card its out of spec and its being resolved well we hope so...

This sums it up nicely just in case peeps have missed it

Well yeah you have the problem when some budget board has been made to barely, "sort of" meet the spec meets a GPU that goes way over the spec - the results could be somewhat unpredictable.
