I think that you are alright with just using the one 4-pin 12 volt 
connector, but I'm just guessing.  This is why I suggest that you pose your 
question to Biostar's tech support.

If the previous information about the 2x4 connector being necessary for 
processors using 130 watts of power or more; then, your Windsor is just 
under that limit, as I see it is a 125 watt CPU.

It actually draws more power than the new quad-core Phenom, since the 
Windsor is a 90mn process CPU drawing 1.4v and the Phenom is a 65nm 
processor drawing 1.25 volts.  The current Phenoms are only shown as 95 watt 
CPUs.

Sorry I can't give you a more definitive answer.

Subject: 8 pin cpu updated question

since the motherboard (am2) can also support a quad core cpu, is it possi=
ble for a dual core i only need the 4 pin?


I GOT BIOSTAR TA770 A2+,,,,WITH A AMD ATHLON 64X2 DAUL CORE PROCESSOR(WIN=
DSOR 3.2 GHZ NOT OVERCLOCKED),,,1 GIG DDR2 800.

  AND I DID PUT THE 4 PIN CPU POWER IN IT ,BUT THE CPU SOCKET ON MOBO IS =
8 PIN.
NOW IT IS RUNNING FINE, BUT ITS MY FIRST DAUL CORE CPU. NOW WOULD THE EXT=
RA 4 PINS BE FOR A QUAD CPU? AND MY DAUL IS SAFE WITH 4 PINS?

         NOW IN MY UTILITY MONITOR IT SHOWS

    CPU TEMP=3D 26C
    CPU FAN=3D  3000 RPM
    VCORE=3D    1.42 VOLTS
    VBAT=3D     3.36 VOLTS
 THEN NEXT TO VCORE, SHOWS A BATTERY LIKE VCORE BUT NO NAME, BUT HERE ARE=
 THE VOLTS FOR THAT  3.3VOLT,12VOLT,5VOLT,AND 4.7VOLT=20=20=20=20=20=20
