Power led of my gpu flashing..

[Distorted]

I have a Gigabyte 1060 6gb gpu powered by a Thermaltake 600w psu (buy a new psu comments in 1...2..3)and on some games the white power led above the 8pin (which indicates power) flashes sporadically..It has no affect in the game and the temperatures are normal..In the manual the flashing means "abnormal power".Anyone else have this "problem"?

I have an AGP card like that and let me tell you that the total wattage is not all. You need enough amperage on the 12v line to supply the gpu. If inside the psu all rails are connected together then your gpu could be starved when the cpu and the rest are more demanding.

Then go on YouTube to have some basic computer power supply course. It will help you understand.

Try using another 8 pin connector from the PSU if ones available, make sure the power connector has good contact.

Might be a failing PSU or GPU.

Could get in touch with both manufactures about the issue and see what they say. Personally i be looking for another PSU of a friend or getting a Seasonic PSU.

Hmmm.What if i buy a new psu and still have the same issue?

 

[AsRock]

IMO you would know and 2nd you would have a better quality PSU.

 

[natr0n]

Means it has a higher load.

I had a 7870 long ago and it had blue leds that did that.

Think of them as load indicators.

From what i read in other posts with the same problem,tho they have new and stronger psus they still have this problem.Weird..

Faulty gpu, rma it if possible at that point.

Thermaltake is a hit and miss with PSUs...

Abnormal power is coming from the PSU, dirty power could be coming from your outlet too.

Just give GigaByte a shout and see what they say about it. Maybe it's a tad sensitive.

ok "simple explanation coming right up (i hope)"

Wattage (w) is Voltage (v) X amps (a)
an old gfx card may want 240 watts of power.. so the psu has to be able to supply ATLEAST 20amps on the 12v pcie connector. 12v x 20a=240w

Some time ago psu's had a few different 12v cables with connectors, and they had their own seperate 12v supply inside the psu "we call those supplys RAILS"
lets say a xiolin 500w psu had two 12v rails with 20amp each..
this psu happily powered an old gfx card from rail 1 supplying 240w to the gpu, and rail 2 powered all the hard drives and the motherboard..
you may think 2x240 = 480w so how is it a 500w psu the answer is. 5v and 3v also have wattage ratings. so they can call it a 500w psu.
(some bad psu's used have high amps on 5v and 3v so they can claim they are high wattage psu's, "its easier to have high amperage on low voltage" that does not happen as often any more)
but for the above example the psu works just fine gpu is working great. Life is good!

But now you buy a new gfx card the new card's box says it needs 300w of power..
This is fine you think my psu is 500w ! 300w is no worries at all
But wait a second.. 12vx20a = 240w !
The psu will not work because it does not have enough amps on the 12v rail that supplies the card.
If you could however use both 12v rails together to power the card it would be able too..
(if the card has 2 power connectors then that is possible)


most psu's now only have 1 single rail and the amps are almost always 40+ and they go quite a bit hhigher than that too.
this allows the psu to power the whole system from 1 rail. and it also means the Rated wattage better reflects what you need to know..

e-bear is describing a single rail psu which bearly has enough amperage for the gpu . so when the rest of the system is also using a lot of power the psu just cant quite fully power everything.


Having explained that. lets talk about your gpu.
the 1060 needs 20amps to not crash when you do anything taxing with it. and it needs about 35amps to work properly.
so you would really want 40amps MINIMUM on your 12v rail to power the whole system.

what you need to know is Do you have enough amps on your psu to power the system properly.
Id always use occt to test this and check the 12v power reading..

I would tend to lean more towards you having ripple rather than anything else which would probably make overclocking a bad idea. but the psu could be fine and within spec, the led thing may just be nothing to worry about at all..
Cant tell you really, we can only help you understand and tell you what to try so you can figure it out.

Thank you very much for the explanation.According to this i get 480w

 

[LFaWolf]

Man, how old is that PSU? A quick search shows at least 7 or 8 years old? If so you are on borrowed time for a bottom barrel PSU like that.

 

[Distorted]

Yep.

Btw ive seen more expensive newer ones fried in a year

 

[Shambles1980]

according to the specs on the side of the psu, that psu was about the minimum acceptable for a system with that gpu. its probably under a lot of stress at full load.

480V is minimum?!Most 600 PSUS have this output.

480W over 40 amps minimum for a 120W card ? Man, I find it astonishing that in 2019 these mind numbing claims about cards and how much power and current they need still haven't gone extinct.

The PSU provides more than enough power for this card, whether or not it might be defective is another matter. Stop spreading this absolute nonsense.

the 1060 needs 20amps to not crash when you do anything taxing with it.

No it doesn't , 20 amps means about 240W , this card will never ever even get close to pulling 20 amps on the 12V rails.

Total system power and overclocked. Let's be generous and assume there are 50% spikes in power, that'd mean around 400W or about 30 amps , the absolute highest power draw you'll ever see for a typical system sporting this kind of card.

Exactly.These cards under full load (overclocked) usually dont exeed 350w.And if they do is for milisecs.

Yikes...yikes...yikes. some misinformation in this thread.

Get a new psu... 7 year old 480W 12V of 600W psu and GPU is flashing about abnormal power.

This is (very likely) NOT a fancy card with LEDs that change with load. The OP already mentioned it was abnormal power from the manual.

The psu, IF working properly would have enough juice to power his system (what cpu do you have distortion.. fill out specs please....)!!

These cards under full load (overclocked) usually dont exeed 350w.

Que? Microburst in spec are irrelevant. Respectfully, may I ask how you know of that but dont have the basics understood? Seems backwards!

For all intents and purposes, even overclocked that card isnt pulling more than 175W.

 

[Distorted]

Its actually a Gigabyte G1 1060 6gb.I refuse to believe that this power is Inefficient for this card.I understand that it might got unbalanced cause of age.

 

[Vya Domus]

The power is adequate in principal , the PSU itself might not be. Only way to know is by using a different PSU, thought since you have not seen anything abnormal about your system outside of that indicator I don't know if there really is a problem or not.

Like I said, the card does not have LEDs that change color with power load (like @natron said earlier). Solid is good power. Flashing is unstable power. The card is sensing something...

You dont have to believe it... but....that doesnt mean it isnt true and you should replace that aging old style psu at your earliest convenience.

Again, can you fill out your system specs so we can better assist?

Lol, yeah... psu...IF FUNCTIONAL shouldn't have any issue powering that system most in here know that already)... but your light is flashing for a reason (try reseating it).

....Have you ever thought that maybe Gigabytes sensor is crap?
