Warning connection aren't what seems to be

[KaptCrunch]

motherboard connector(on the left) and PCI-e (on the right looking @) and middle

notice the power changes from one side of the molex to other REVERSING polaity

with modelur psu have wires all black and not identified or tagged what plug is can lead to trouble

[_dangtx_]

i believe they kept the 4+4 design to differentiate from 6+2,visually. but if they're together and you're in a bit of a hurry, or perhaps low light conditions? you could try to plug the wrong one, i guess :)

uhhh... on the top(in the images) left to right:
bevel-square-bevel-bevel.
while the other connector is:
bevel-bevel-square-square.

You would have to really force it.

The connectors are keyed to prevent them from being inserted into the wrong sockets. Ever tried to plug in an ATX connector backwards?

Agreed. Only way this could be a factor is either :

a. you force the connector in ridiculously (which would probably break something), or
b. your MOB has some extremely poorly made connector that doesn't have the different shapes in it (and you choose to use the wrong connector in it).

umm.. I find it's pretty easy to visually differentiate, plus the physical connection is pretty idiot proof..

well i just chked the connections again... i changed the 8 pin on the card to the pci exp since i thought that it should go in.. i thought only 1 was needed.. also i changed the 8 pin for the cpu.. so i think it should be fine... then i tested it turned on. yay. but it was a black screen.

yeah that i was thinking Bond007 poor made receptors sockets, good thing person quoted above had a smart enough psu to shut off.

I'm not surprised by this at all. And in my years of support / troubleshooting, I have seen a 20-pin connector installed backwards... "oh, PSU died, I replaced it and I can't start the computer anymore".
