12v rail question

I have a Corsair 650w PSU which I'm just installing in a new rig. It's a while since I've built a computer so I'm a bit rusty.

What I'm assuming to be the 12v rail connector ( the PSU lead which is not modular alongside the main mobo connector ) has two components of four connections. The mobo, a Gigabyte 770TA-UD3 socket AM3 quad-core board, has an eight pin 12v rail receptacle . Now, one block of four pins on the PSU lead will fit one four-pin socket unit on the mobo receptacle but the other half of it won't. You know, the ' fool-proof ' shaping won't allow it. I'm guessing that all will be well with just one of the PSU lead four-pin connectors attached to the mobo. Am I correct ?

It tells how to hook it up on page 24 of your manual

No, it describes the socket on page 22 but doesn't make things clear. If you look at the diagram of the ATX_12V_2x4 socket on that page- my PSU lead ( half of it ) will connect to pins 3,4,7 and 8. That's GND, GND,+12v, +12v. Is that adequate ?
My other half of the PSU connector consists of four curved pin shapes, which of course does not fit the mobo socket.

However, my question is- will my connection run the quad core Phenom II OK as it is ? I'm all assembled and waiting to power up.

Thanks for the online manual, incidentally, that makes it easier to describe my problem.

When using a power supply providing a 2x4 12V and a 2x12 power connector,
remove the protective covers from the 12V power connector and the main power connector on
the motherboard. Do not insert the power supply cables into pins under the protective covers
when using a power supply providing a 2x2 12V and a 2x10 power connector.

1 x Main connector (20+4Pin)
1 x 12V(4/8Pin)

You should be good to go as I read it

Well, no protective covers existed on my board, but I can't see that any other configuration is possible. So yes, I think I'm good to go too. Back when the smoke clears

OK, she posted and no smoke.

I'll take my Windows 7 newbie questions over to the Software hangout. Cheers.

Glad to see there wasn't any smoke, brings back some painful memories from long ago and far away.

Good luck with Win 7
