Does the i7 require a 8 pin?

My power supply does not have a 12v 8 pin connector, but just a 4 pin connector. Is that enough for the intel core i7 77 watts? or should i buy a molex to 12v 8 pin connector. thanks

    What does your motherboard have a 4 pin or 8 pin auxillary power. If it has an 8 pin then it probably won't power up.
  2. It has a 8 pin one next to the cpu
  3. \The additional 4 pins were added to support the higher power draw of newer (at the time) Core 2 Quads. The 4 pins will happily provide power to most lower end CPUs, but if you have something like an I7 I would double check the TDP and make sure you can provide enough power with the 75W that the 4-pin can provide and that you don't need the 150W that the 8-pin provides. Personally I don't think it will work and even if it does I would still upgrade the power supply so you have all the right conections given off the right amount of power.

    But I was just thinking of going with a molex to 8 pin as it is cheaper. Will it still work with the adapter?

    You mean something like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16812887002. Yes that should work fine.
