hooking power to a motherboard

[robertemmer]

I am about to get a P4 3.4 ghz chip to put on a P23g motherboard. There are 2 power connectors. The usual atx 20 pin connector and the 4 pin square 12v power connector. My power supply presently doesnt have the 12 volt connector. It says in the manual that its for "vcore" items. I dont mind buying a new power supply but wont if I dont have to. So my question is what is this 12 volt connector for. I got on the net and found myself here. Any help would be nice. Thanks.

This square connector is usually found on newer power supplies.

Older power supplies may not have these.  It allows you to connect to a P4 mobo.

you'll be ok without the 12 volt connector on that mobo*

^ if the above mobo is the one you have, your ok with just the 20 pin connector for your needs*

Yes it will be the MB but its V 1.0, not V3.0 according the store Im buying it from. Is there a problem If I do get a PS and put this 12 volts to the connector or will I fry the whole darn thing out? If it boosts speed of course I want to but Ill wait for a reply. Thanks for the quick replys already.

you will not fry anything plugging in the extra 4 pin connector...
if your getting the 650 pentium  "sweet choice" !!!

Its the 651. What exactly is the 4 pin connector for so I have some informed consent.

Your four pin connector is for vcore components...

VCORE is the operating voltage of a CPU or GPU (or other device containing a processing core). It can be altered to help overclock a processor by reducing the time the circuit's logic gates take to switch states. - Wikipedia

If your BIOS permits it, you can overclock your CPU, graphics, etc., using the voltage from your power supply.

Here's a program you may want to look into:

I have that program. I looked up Vcore myself and found what you did. I dont want to overclock so Im thinking this plug I dont need? I guess Ill read my manual to figure this out. Money doesnt grow on trees so I dont want to screw anything up.
