Windows 7: 6+2 pin power connector into 8 pin socket?

6+2 pin power connector into 8 pin socket? Urgent!

Hi, I have a motherboard which needs an 8 pin pwer connector to supply the cpu properly, my question is: can I plug in my 6 and 2 pin power connector into it? will it work?
Currently I'm running only on 2 cores with my 4 pin power connnector
some say it works: 6 Pin to 8 Pin - Graphics-Cards - Graphic-Displays
If this is not a good idea, I will get a molex>8pin converter in the future, thanks.
edit: I have a Coolink 500W

Realistically you can use any 12v connections as long as they will fit in the socket, which is where you would find the problem.

The CPU connector is very simple:
12v 12v
GND GND
for the 4-pin
and
12v 12v 12v 12v
GND GND GND GND
for the 8-pin

By convention 12v wires are yellow.

Acceptable: get any four 12v connections to fit in the socket.
Better: Buy an 4-pin to 8-pin adapter (just a splitter, really)
Best: Buy a modern power supply. Your puter will love you for it!

You want to plug a 6+2 pin PCI-E power connector into the 8 pin +12V CPU power socket?

I'm not sure that it fits. If it did, the pinouts appear to be different.

I think you'd be safer to just use the 4 pin ATX +12V connector. The last few motherboards I've bought included caps in the 8 pin socket so that a 4 pin plug would go in the correct position.

The thread is already marked as solved, the pcie connectors seems to be fitting the 12V ones, but their end has inverted shape, my issue was a software issue:

I noticed that the thread was marked as solved, but it read like it would be OK to plug a PCI-E power connector into a CPU +12V socket. I'm fairly sure that is false, even if it is physically possible. I believe that major damage would result.

The power connectors for a PC are keyed so as to dummy-proof installations for the do-it-your-selfer. The correct power supply plug made for a specific socket will only fit one way, avoiding damage that can be cause by reversing the voltage/ground polarity. And it also helps that the power connectors needed for each device are easy to recognize in pictogram fashion to minimize technical support calls.

But beyond that the power supply wiring in a PC is pretty straight forward. You've got 12v (yellow) wires and (black) ground wires. The power supply does not send out any "special" current to the 12v wires on a PCI-e connector. It's just 12v.

Some of us have been know to use an razor knife to round off the square keys, or snip the wires and twist new connectors on to them to jimmy connections. And yes this does, technically, damage the parts. But as long as the correct voltages and polarity are applied, none of this will fry the motherboard or the attached devices.
