Oh and as for pcper as a whole

pcper said:
In this shot, we are using the same data but zooming on a section towards the beginning. It is easier to see our power consumption results, with the highest spike on total power nearly reaching the 170-watt mark. Keep in mind this is NOT with any kind of overclocking applied – everything is running at stock here. The blue line hits 85 watts and the white line (motherboard power) hits nearly 80 watts. PCI Express specifications state that the +12V power output through a motherboard connection shouldn’t exceed 66 watts (actually it is based on current, more on that later). Clearly, the RX 480 is beyond the edge of these limits but not to a degree where we would be concerned.
here is another from their written review, now keep in mind the 95w power draw was overclocked.

pcper said:
I asked around our friends in the motherboard business for some feedback on this issue - is it something that users should be concerned about or are modern day motherboards built to handle this type of variance? One vendor told me directly that while spikes as high as 95 watts of power draw through the PCIE connection are tolerated without issue, sustained power draw at that kind of level would likely cause damage. The pins and connectors are the most likely failure points - he didn’t seem concerned about the traces on the board as they had enough copper in the power plane to withstand the current.
they also seem to rather like the card

This idea of average load vs. power peak spikes argument is a diversion that favors Nvidia's lower average due to it's more extreme oscillations.
If you would agree that overclocking cards like the 750's and 950 SE exceeds the power specs for PCIE, then where are all the broken mainboards?
No, the average vs. spike argument is because an average load over time heats things up and can kill hardware. A spike doesn't heat up the connector and cause damage.

The 960 might spike to 225w, but a lot of cards spike pretty damn high, it is a byproduct of DC to DC conversion. The difference is the GTX960 overages significantly under spec on average, like only pulling ~30w from the PCI-E slot over time. So the connector doesn't heat up, and there isn't a risk of damage. The RX 480 on the other hand average way over the spec, which will heat things up and can cause damage.

The funny thing is, I've seen a 24-pin connector melt on a PSU with two 480s connected and folding...they just weren't AMD's 480, they were nVidia's. It wasn't exactly an ancient board either, it was a ASUS 990X based motherboard. And the PSU wasn't a slouch either, it was a Corsair HX850.

Well, this is where the concerns should be placed... on those running multiple cards in a system. 16W on a single card becomes 48W on three cards. And since AMD doesn't have a 2-card limit to the number of cards in Crossfire configs, this sort of thing is something people who are considering such rigs need to consider.

This isn't a huge issue at all, however, it is something that needs to be considered depending on how many of these cards you might plan to use.

I agree, this isn't a huge issue. But definitely an issue that needs to be addressed. The people that are downplaying this and saying the issue isn't really an issue are just plain wrong. It is causing problems. They are saying don't worry because newer motherboard have protection to stop damage. Ok, fine. But my machine just shutting down randomly is an annoying f'n issue that I'd want fixed. It definitely isn't "no real issue".

Plus, as with my experience with the GTX480s, the problem worsened over time until the connector completely melted. I didn't even realize what happened until it was too late. The machine ran fine for almost a year. Then started randomly shutting down about once a month. Then it started happening about once a week. I did visual inspections, all looked fine. I even wiped and re-installed Windows once it started happening once a week. Then one week it shut down every day for about 4 days straight. Then then finally it shut down and wouldn't power back on. It wasn't until I pulled the computer completely apart that I found the burn/melted 24-pin connectors on the PSU/Motherboard.

And that is the thing that concerns me, even with only running one card. Over time, if you are constantly over-driving the connector, it can deteriorate. And the problem with a power connector is, when it start to deteriorate it takes more current to overcome the resistance of the poor connector. More current and more resistance means more heat at the connector. It is just a snowballing affect until failure.

I'm not saying this is something that is going to happen all the time. But even something like dirty contacts cause cause more resistance and a higher potential for failure. So it is definitely a possibility. And there really isn't any reason to pull that much power from the PCI-E slot. The 6-pin/8-pin connectors are way overbuilt. The extra power should be pulled from that connector.

And obviously custom designed cards aren't likely to have this problem anyway.

To be fair most of the boards that would have 3 RX480's would have an add on connector on the board for more power to the PCI-e

It's funny that so many think that AMD should have put an 8-pin instead of a 6-pin, as if this would changed the power draw from the motherboard slot.

I haven't heard of any credible article where someone lost a mainboard due to the RX 480, have you?

As i heard it he tested a 775 setup were as he said some one else tested the AM2.

But again OMG few days later and the card looked like this Sheesh.

Well what do you expect when most of their fanbase are mostly manchild/literal kid

you cant have a good gaming experience if you dont have the GeForce GTX® logo/sticker in your PC afterall :^)

most probably doesnt care about efficiency either, or they are simply too new to remember the HD5xxx vs GTX 4xx series
And exactly what are you doing? Both sides fanbois are nasty and cruel, and arguing about shit that just doesnt matter while they throw insults like you just did.

And for the record, most of TPU's membership is well over 30, with alot of us in our 40's and 50's.

Did you not see my screenshot? My GTX 970 runs "346.03".

There are also Linux users using non-proprietary blobs that provide basic acceleration. If a system fires up any compute, you could run into problems, especially considering it's likely to beat any game power draw.

I don't have any evga 'gaming' software' to run, I don't have GPU-z to tweak things, I have strictly the on card BIOS to control cooling of the ACX2.0 fans. If it were driver controlled thinking it was a blower, the 'off' feature at low load/temperatures wouldn't function.

An RX480 trying to pull >75w through my pcie slot would actually start causing stability problems if it doesn't actually cause any physical mishaps from the overcurrent, as is very well documented in eGPU setups already.

Edit: On a side note, this is why the 'bullshit' reviewer bios fiasco is also very important to me. I can't necessarily take advantage of an overclock if it's not preset.
If you run Linux and "compute" you're not an average user and you've heard about RX480 "issue". And you don't seem to understand BIOS/driver relationship at all either. Drivers don't "assume" you have a blower cooler on your ACX EVGA graphic card. It KNOWS you don't have it. That's why AIB's have different hardware ID's to identify specific hardware, so that driver doesn't "assume" things like this, but it "knows" things like this.

pcper just gave us a second view of things on rx480 and i like the explanation and data.
maybe tomshardware+others should have not get it out so quickly and talked to other sites before making it big.
i think this is blown out of proportion.

I wonder if GTX 960 Strix was brought as a paradigm from those defending Nvidia. It's a card with an extra power connector and TDP much lower than 150W. Whatever spikes it produces the average consumption from the pcie bus will always look under the limit.
But tell someone about an overclocked GTX 950 without a 6 pin connector and ignores you, changes the subject, or wants you to believe that you can have 20% extra performance without consuming a single extra watt. Free performance.


Instead of people start asking if there are other graphics cards out there depending too much on the pcie bus, or sites starting tests to see if under overclocking specific graphics cards could push the pcie bus over it's specs(the GTX 950 I mentioned, the R9 270X with only one pcie connector could be another example, GTX Titan Z, R9 295X2), this ends up again becoming the favorite subject for many people. How to attack a new product from AMD.

One more opportunity to attack AMD, a lost chance to investigate on something important and probably learn something we seemed to ignored until today and probably we will ignore it in the future, starting after tomorrow.

Yeap. A fact that many try to hide behind their little finger.

I can't even understand why peoples trying to, or experimenting if their motherboard would crash when used with reference RX480.

A power overload wouldn't crash a computer unless it's so grossly overloaded that it'll trip PSU OPP/OCP, or drop the PSU rail significantly under ATX spec. The PCI-E power delivery is just straight connected into power and ground plane on PCB, almost no other component inbetween to be directly affected other than the connectrors itself. There's no power limiter, power sharing controller or whatever on the motherboard itself. Just direct connection!

If anything, the problem wouldn't show itself so quick. A newly inserted power connector and PCI card is literally the best case scenario for power delivery. The contacts are still shiny new, no oxidation, no dirt, and the scratch created during card insertion would help with removing the already existent oxide layer. Wait some month/years till the contacts oxidated, increasing the contact resistance. By Ohm's law, heat generated by the current flowing in the contacts will increase and depends on the material, maybe it'll melt the plastics on the contacts.


A bad motherboard that skimp on using proper power plane and ground plane, using skinny traces instead, is another story. It could literally burn.

As much as the 480 is in that last video some one posted, like OMG he only just got that lol.



His problem not ours, still don't mean the info he found was not bad or good.



As i heard it he tested a 775 setup were as he said some one else tested the AM2.

But again OMG few days later and the card looked like this Sheesh.

That's racist!
