Just got my power supply, mobo, vid card today; still waiting on the rest of the parts. Anyway, I was examining my psu, which is a corsair tx750. As I'm examining the 8-pin ATX12V connector, I realize it is keyed differently than how it is displayed in my mobo and psu manual.
This may be difficult to comprehend unless you are familiar with these cables, but I'll do my best. The 8 pins in the connection come in two different shapes, square and hexagonal. The picture provided in my manuals show that it should look like this...
[Hex][Square][Square][Hex] <----- Top Row
But the only 8-pin connector provided with my psu looks like this...
[Hex][Square][Hex][Hex] <------ Top Row
I'm quite confused about this, I highly doubt it is keyed incorrectly, as it seems like this would be a major manufacturing error. I know this connection is not the pci-express connection, as my psu doesn't come with a solid 8 pin pci connection. So if anyone could enlighten me, thanks...
The manuals are wrong. Look at the ATX+12V socket on your mobo and I'll all but guarantee it matches the pin shapes of the plug. The 8-pin plug started out life as a 4-pin plug in the HS over SH configuration. When it went to 8 pins the other 4 were all hex, but the manual publishers cheaped out on their graphics and just flipped the 4-pin picture over to create the 8-pin picture. My own Abit IP35Pro manual has the faulty pic in the manual, but the cable slotted home with no issues.
This is nothing more than Taiwanese manufacturers saving a penny per manual and unnecessarily agitating the gerbils.
