Low Power Motherboard 4-pin Motherboard CPU Power Cable Instead Of 8-pin One?

4-pin motherboard CPU power cable instead of 8-pin one? - low power motherboard

I bought a new motherboard Biostar TA770. I realized that the board is not an 8-pin CPU and mainboard has the usual 4-pin. My new power supply does not have 8-pin connector, but I've read that 4 pins for processors with less fuel consumption, including the 65-nm CPUs 65W or less.

Now, using this information, two things: that you can use 1 4-pin, or use 12-pin to 4-pin and put 2 x 4-pin in the 8-pin.

There is work these things? Or is it desirable? I buy a different outlet, and cursed, but I'm buying a new power supply.

Thanks for the help!
