Which power cable for CPU on my mobo?

post #1 of 9
Thread Starter 
My power supply, seasonic x650 gold, has two different cpu connections, and i dont know which to use.

they both have the same connector for the mother board, but the end that goes into the power supply has two options
one is a 8 pin, identical connector on each end from motherboard to psu.

the other has a 8+4 pin, which matches a pci express plug.

which do i use for my i7 2600k? i cant find this in any of the literature for the psu, i7, or mobo??

use the 8pin, your board has an 8pin on it.

I believe the X-650 has the two 8-pin connectors for dual-CPU motherboards. If you were to use it that way one would go in the PSU CPU socket and the other in a PCIe socket. However, either cable will work for your 2600K.

ok. also, i mounted the psu with the fan pointing down thru the bottom vents on the HAF 922. is that ok? the user manual said the fan should point into the case, but "in some cases it doesnt"

is this one of those cases? will the tiny bit of ground clearence be ok for that fan to blow air out?

it made sense to me this way because otherwise the psu was upside down, and it would be blowing all its hot air into my pci area

That side of the power supply is an intake and won't blow outwards.

Actually it pulls air in and shoves it out the back. Regarding clearance, that's kind of a based on your assessment - I'd wager that there's still enough space for it to pull in enough air, but if you think otherwise, better safe than sorry.

Just ignore it. I've never bothered figuring out what it is and haven't had issues.

Edit: Apparently you can limit the drive to 1.5Gbps by using a jumper on the correct pins.

i appreciate all the help guys and REALLY appreciate the fact that your responses were so quick. i never like to build my own PC, my first one ever, many years back in highschool, was a disaster. I pay 50 bucks to have them built for me. but i pulled this one off, always afraid that i would find out i ruined it somehow, and it posted to bios without problems!

i have to find my damn windows 7 disc to install since i got the win 7 pro for 30 bucks for students, as a download and product key.

i will also post pictures i think i did a pretty good job with cable management, and the rosewill tools kit made building a pleasure. the HAF 922 was incredibly easy to work with as well, tool-less hard drive and optical install were a blessing, and i loved the removable panels.

anyway, i will rep u guys for the help, and wish me luck overclocking. bios reports me idling at 25C for the cpu.

my stock voltage is 1.22 which i think is a pretty low one for an i7 2600k, happy on that, but my stock frequency is 3.498 ghz, so i basically got an exra 100mhz free out the box, and i have a good feeling it will oc well.
