There's a lot of misinformation on this thread.

To summarize things, TomsHardware's graphs show a RAW power consumption with no filtering, as PCPer says these spikes are generated because of DC conversions when turning off and on in cycles to provide power, Tomshardware gets the most precise numbers with inductive measuring and RAW data while other reviewers like PCPer have different methodology that aren't capable of faithfully showing these spikes with their filtered results as these happen in such short time spans.

Many have said that the reason why this have been blown out of proportion is because of hardware damages, but this is ridiculous because the RX 480 is proven to have short spikes to 140W compared to other cards like the GTX 960 to 240W from the PCIe Motherboard slot alone, or the 750Ti with spikes above 150W with stock/reference settings.



"LEAVES THE MOTHERBOARD CONNECTOR TO DEAL WITH UNPRECEDENTED UNFILTERED POWER SPIKES ON ITS OWN"

Many people see this image and are amazed to see such power spikes, they are so impressed by these results that they ignore completely the description above pointing out that these are the motherboard PCIe X16 Slot results without any PCIe Power PSU Connector and go on to reply misinformation about this being the card's total power graph, which is not.




TomsHardware inductive measurements show how spikes for the 750Ti can reach up to 150W, which occurs approximately 19 times every minute, it's especially ironic that people are crying out loud for the RX 480 when the 750Ti behavior is what end up damaging electrical components because of thermal fatigue and weak spots.

None of this was ever discussed before the RX 480, gee, I wonder why?






DISCLAIMER: THE POST ABOVE MAY CONTAIN FACTS, DISCRETION ADVISED.

DISCLAIMER 2: I BELIEVE THE RX 480 IS A POOR EXCUSE OF A CARD, THAT POLARIS 10 IS INEFFICIENT AND WEAK

DISCLAIMER 3: I BELIEVE POLARIS 11 IS A MARVEL AS IT WAS THE FOCUS OF THIS ARCHITECTURE, I BELIEVE THE RX 480 IS POLARIS STRETCHED OUT (SACRIFICING EFFICIENCY) INTO A PERFORMANCE BRACKET IT WASN'T DESIGNED TO BE IN.

DISCLAIMER 3: I NOW OWN A GTX 1070 AND NO AMD SHARES.


Thank you everyone.

The spikes are normal. When you turn a circuit on... it will spike for a a very very very short time (usually measured in microseconds). It is the same thing that happens when you flick the switch to turn on a light bulb. All circuits operate this way. What you want to do is filter those out in order to get a better idea of the true sustained load. In doing so (as PCPer did) you get the proper results.

You are new to this stuff eh?

On another note... if you think you can come here on overclock.net and spout nonsense to a very knowledgeable user base... then you are wrong. My suggestion to you Mr Dragon is to fly on over to wccftech and breath your fire over in their ever-so knowledgeable comment section. I am sure that the ensuing flame wars there will be more to your liking.
