8 pin ATX and 24 pin ATX

[pocket007]

this is my first pc build....and to be quite honest all these cables are stressing me out....i dont want to burn anything up...i have a asrock p67 extreme 4 mobo and an OCZ 1000 watt PSU..my question is...do i use the 24 pin ATX in conjunction with 8 pin ATX...or do i just use the 24 pin by itself?

i have very little knowledge as far as pc building goes ...so any help would be most appreciated

You use both the 24 pin and the 8 pin at the same time. There are connectors for both of them on the MB.

You need to use both motherboard connectors. The 24 pin provides power to the board, RAM, expansion cards, any fans connected to the board, etc. The 8 pin connector provides power to the CPU. Your system will not boot if either one of these connectors isn't plugged in.

I am also putting together my own computer.

I used the 24 pin and the 8 pin connectors from my Coolmax CUG-950B 950 watt PSU. I noticed there are two 8 pin ATX 12V ports on my Gigabyte G1.Assassin mobo. Do you think I need to have 2x 8 pin ATX 12V? My PSU only has the one...

I am still waiting on the Intel Core i7-960 so I can't fire it up until that arrives. I was just curious if anyone knew if I needed 2- 8pin ATX 12V or if one of them will work? I don't plan on overclocking or anything like that.

It read the mobo manual and it didnt explicitly say it needed both it just said you must connect the 8 pin ATX 12V connector from your power supply or your computer will not turn on.

My guess is they give you two connectors because the hexacores on LGA1366 can be a power hog, and you may go beyond the capabilities of the single 8 pin if you do a sufficiently high overclock. You might be able to get away with the single 8 pin, but I wouldn't try to overclock your CPU in that case. Coolmax PSUs are notorious for their poor quality and for not delivering what they say they can, so I wouldn't encourage you to try using an adapter if you do need the additional connector. If you plan on doing a lot of overclocking, or a high end SLI/Crossfire setup, get a better quality PSU.

Thanks for the advice. I have read similar posts about Coolmax not being the best brand and not delivering on their claims. I guess I found the price for a 950 watt PSU too hard to pass up. If it doesn't work out I will probably end up changing out the PSU because everything else I got was fairly high-end. The PSU's with 2 8 pin connectors were pretty pricey maybe the adapter is the answer.

Thanks again.
