LOTS of GREEN SMOKE!!! Can i burn card if i connect to much power?

d359233drdrbcom · Jan 26, 2014

the card only needs two 6pin connectors. I connected two 8 pin
this changes 150w to 300w.

also the pci-e slot from mobo gives 75w. if old pci-e version. new gives 150w 150w + 300 =450

I used a powered riser so i can raise the card out of hot pc.It uses molex to add extra power.

How much power does molex give?

450W + ?W = ???W

What? Green smoke? That's not good. 6 pin is 6 pin the wiring on 8 pin are different which I don't know how you plugged an 8 pin in 6 but yes you can fry the card

d359233drdrbcom · Jan 26, 2014

why was the smoke green?
what should i do with the card now?

but can i fry the card cuz of too much watts?

also how much watts is molex????

Memhorder · Jan 26, 2014

molex gives +12 volts Basics:

molex connector = 36 watts (12v)

6 pin pci-e = 75 watts

8 pin pci-e = 150 watts

The 6 and 8 pin connectors have 3 12v wires supplying them and they can come from 1, 2 or 3 different rails depending on how the power supply was designed.

Smoke was green because that is what happens when copper burns

d359233drdrbcom · Jan 26, 2014

Memhorder :

so molex must be 3 amps

but can too much watt conencted fry card?

Memhorder :

insightful

Memhorder · Jan 26, 2014

If you can hook the 6 pins into it and try it. If not then your GPU might be a fancy paperweight. You may be able to call on your warranty. I wouldn't tell them you tried what you did just say you used the 6 pin and get a new one

d359233drdrbcom · Jan 26, 2014

what if i try it again with a new card?

will too much watts cause the new card to burn too?

This is just an Idea on making green smoke.

Copper Chloride when it burns produces a green flame and green smoke. SO in theory this should color the smoke.

Needed :
12 part Potassium Nitrate
10 part Copper Chloride [Solid]
8 part Sugar
2 part baking soda

Melt the ingredients together on a gentle heat then form small pucks.

Stick a fuse in then ignite it

Should produce Green Smoke

There do that if you like green smoke

You can't overload a card by hooking up too many power connectors, the PSU pushes out 12V to those power connectors, and the card draws as much power as it wants from them. A PCI-e 6 pin is rated to provide up to 75W of power, the 8 pin is rated to provide up to 150W, they don't shove this power into the card though, it only provides it if the card needs it.

The main question here remains how did you put an 8 pin connector in a 6 pin slot and did you use an 8 pin PCI-e connector or an 8 pin EPS connector by mistake?

Can you provide a picture or two of how you had it set up? Imgur and photobucket provide free image hosting, this will help figure out what went on. Also details on the specs of your setup and the make/model of your PSU.

As for the green smoke, i've never seen it be green before, copper makes a green flame when it burns but a dark smoke, ICs and caps usually release a dark somewhat purplish magic smoke, you can tell its magic smoke because of the atrocious smell!

there are 6 pin to 8 pin cables.I used them in a way they werent designed for (other way around)

You certainly can fry it if you connecting a hot wire into a ground thus the "green smoke" obviously something is burning due to a short circiut.

d359233drdrbcom :

Define "other way around".

Be aware that a 6 pin PCI-e cable is 3 yellow on top and 3 black on the bottom, but an 8 pin adds 2 black to the side, at that point if you shift it over one in the adapter you now have hot shorting directly to ground which will cook the traces on the board and the wires if you don't have a good PSU that quickly detects and cuts power to the short.

How the hell did you plug that in?

d359233drdrbcom · Jan 26, 2014

hunter315 :

isnt that the standard from atx v 1.3? or some other version?

what is the difference beween atx 2.3 vs 2.31 vs 2.32 vs 2.4? cant find any info on these

Memhorder · Jan 26, 2014

Do not do that on a new card because it will suffer the same fate

d359233drdrbcom · Jan 26, 2014

Memhorder :

I used a 6 pin to 8 pin the other way around using another cable an 8 pin to 8 pin extender/riser

Memhorder · Jan 26, 2014

power efficiency and lowering of the 12v minimum

d359233drdrbcom · Jan 26, 2014

Memhorder :

can you please post source?

which atx do you mean?

zeph_yr · Jan 26, 2014

Maybe you should take it to someone who know what they're doing... I hope you didn't fry your card, but unless you're certain you know what to do, don't try anything else.

Memhorder · Jan 26, 2014

Got the answer here

d359233drdrbcom · Jan 26, 2014

Memhorder :

there are none of these versions here but you can find some psus with this

example tomshardware.co.uk/forum/1998819/last-read

Memhorder · Jan 26, 2014

isn't your six pin off the psu long enough to plug into the header?
