First time builder... motherboard power supply question...

First time builder... wondering what type of power supply I should use to be compatible with my "ASUS P8Z68-V PRO/GEN3 LGA 1155 Z68 ATX Intel Motherboard"? Specs show it has 24 pin for power connector, which is simple enough to find, however for the 12V connector it has 8-pin setup. What is difference between regular power connector and 12V? Also if anyone has any suggestions for a 600-750W product I'd appreciate the help (link or part # please)

  1. 12V 8 pin cable is for CPU. 24 Pin connector is for motherboard. My PC currently runs on Antec HCG-620 (620W) with i5 2400 / H67 MB / 8GB 1333 MHz RAM / GTX 560 Ti 448 Core Graphics Card (requiring 6 pin + 8 pin connector) / Two case fans without any problem. I'm not an experienced builder, as the current system is my first build, but it seems that the most people are happy to recommend Antec PSUs.
  2. By the way, 8 pin connector for CPU is different from another 8 pin PCI connector. They cannot be used alternatively.

    I think this guide will be helpful.

  3. The 24-pin is the main power connector for the mobo, the 8-pin is for the CPU. Your cpu's heatsink/fan will have a 4 or 8 pin connector on it to mate with this 8-pin 12V connector on the mobo.

    The 12V connector would be relevant for the CPU you buy to go with it, not the power supply.

    Corsair builder and enthusiast series are the best options for your wattage range, and good quality. Many folks think the best thing to is get a GOOD power supply - like a Corsair, instead of a cheaply-made, less expensive alternative.

    Huh ?
    CPU HSF has a 4 pin fan connector, can't connect it to the 8 pin 12v connector
    Don't need any more confusion

  6. Yep you're right. That came to my mind during my commute and I thought, "I am an idiot..."

    Sorry for any confusion.

    The 12V 4/8 pin connector is only for the CPU power on the mobo.

    Generally 95W+ CPUs need the 8 pin, less can use a 4 pin.
