Question about 6/8 pin Connectors

post #1 of 3
Thread Starter 
(kind of a graphic card architecture question)
Does not plugging in any of these connectors cause any damage to the card?
(no since I`ve made the mistake of power on with unplugged connectors)

Normally if you power on a system without its 6/8pins,
the whole system powers up except the graphics card, however the fan may start spinning.

Is there some built in protection against such a case?
or is it simply a case of the card not getting enough power?

I forgot to feed my 2 GTX470's with 2x 6-pin each card...

Man the noise! A very loud squicking noise, very high pitch.

Scared the hell out of me, tought the cards were dead!

Shuted down the PC and connected them again, no problems.

I'll NEVER forget to connect those again... the sound brrrr

Forgetting these connectors shouldn't damage the card. Some cards are able to detect the lack of the 6-pin/8-pin connectors. IIRC, when I had my 8800 GTS, it had an on-board buzzer that triggered when the 6-pin connector was disconnected. And I've had a few Asus cards that had an LED near the power connector (green = OK, red = missing). Don't forget that you get 75W through the PCIe slot, so the card can function in some capacity on that...just no 3D clocks of course!
