Keep up the amazing job buddy. Wccf would be proud of your job making this site an amazing place to spread ideas!

Please do elaborate. Explain how 240W spikes through the PCIe MOBO X16 slot is less harmful than a slightly higher average of 79W with way lower peaks, I'm eager to learn from you.



Those spikes? Ignore them all, the average is still below 75W so who cares that they happen 45 times per minute, I'm sure your Motherboard/PSU don't care because nVidia, your PC components will only care if its AMD.

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.

And you are basically proving my point, this happens all the time with every card, some have it worse than others but every PC component presents this issue, it is just now that the issue is finally somehow blown out of proportion because AMD and a slightly higher PEG Average consumption?

I know perfectly fine how DC power works and how it turns off and on to provide power and why each time it turns on it generates, you'd know if you read my entire post. These spikes happens to be almost twice as bad on the GTX 960 than on the RX 480, yet this is irrelevant?.

Yes, the RX 480 average is slightly higher over the PCIe but with way lower spikes, my question remains unanswered, WHAT IS WORSE?, I can see how intermittent spikes can damage any PC component more than average power consumption with lower spikes.

Again, I'm aware that every PC component presents this issue due to the inherent way electricity is delivered, but it's been proven some suffer higher spikes than others, some being the GTX 960 Strix and others being the RX 480.

The GTX 750Ti, GTX 960, R9 295X2 were never an issue, the RX 480 shouldn't be, the fact that Polaris 10 efficiency sucks is the only issue I see.

No he is not,and no it does not.

Show me a card with a average of 75W+.




Mahigan just told you the spikes are normal and you go ahead and ask one more time the same question? Not happy with the answer? rolleyes.gif

Protip: Both are bad,hence why both of those cards had people worried.

The spikes are normal, that much is well known ever since I first posted, what you don't seem to understand is me pointing out that despite some 100W spikes are normal 240W spikes like the one posted above for the GTX 960 is not, and is probably as harmful if not more than a sustained average power consumption of 79W.

Ok,and? What does that do for the RX 480 PCI-E issue?

Take your Green vs Red war elsewhere if you're not concerned about the real issue.

"The real issue"

I'm happy you have that so strictly defined. For me I'd rather have a slightly higher PCIe X16 average power consumption of 79W with lower DC cycle peaks like with the RX 480 than a lower average power consumption of 73W but 45 monstrous 225W+ peaks over the PCIe X16 MOBO slot every 60 seconds like with the GTX 960.

But that's just me I guess.

Here is some really good info:

Watch about 7-8 minutes or so to see why the card overdraws the slot

You always can buy a different 960.

Can you do that with the RX 480? Not currently since there are no custom card.

Yes you can, the 4GB RX 480 which doesn't have these "issues" (Non issues really), guess you just like the create "Real Issues" as often as possible huh? Bet your next real issue is how everyone with 8GB RX 480s will burn their house down and that nobody can avoid it because the 4GB on the RX 480 that doesn't have these "issues" have another "issue" which is not enough VRAM for 4K super sampled.

NO it does not!

if you have a 150 watt chip then it would have to use BOTH (spec'd) 75 watt sources. and it IS a pci-sig requirement to keep those sources (connector/slot) separate; why the two vrm banks aren't tied together.

Remember the golden rule of statistics: A personal sample size of one is a sufficient basis upon which to draw universal conclusions.
Upload the computer to Dropbox and provide a link to it so others may download it to examine and give advice for repairs.
