My motherboard has both 8 and 4 pin connector for CPU. Which one should I use. I am yet to buy a power supply.
I'd just use that 8 pin. There's no way you can exceed the voltage delivered by a single 8 pin on normal air or water cooling.
the extra 4pin is for overclocking stability unless you pushing the cpu well above a safe recommended overclock you dont need it
I am going to over clock and water cool.
Also, I am not able to find any power supply with a 4 pin connector in the shape of a square. There are only connectors where all the 4 pins are next to each other in a line.
You must be looking at the wrong cable. It's never in a line as far as I've heard.
Power supplies with a 4 pin 12V CPU connector always have the pins arranged in a square.
Some have 8-pin, which is a rectangle twice as wide.
Still others have 4+4 pin, which is two squares that can be used as a 4 or as an 8.
Could you post an example of what you're talking about?
Hi CX 750 watts from corsair.
It does not have a 4 pin CPU connector. Just an 8 pin. What do I do? I will be over clocking as much as possible with water cooling.
Corsair 8-pin power supplies are always actually 4+4. You can use it on a motherboard with a 4-pin or 8-pin connector.
What motherboard are you looking at though? I've never seen one that has a 4-pin and an 8-pin on the same board.
Asus Maximus VI Formula
The 4 pins in a line connectors you are talking about are called molex connectors and they're only used for older tech and to hook up fan controllers. Also, most power supplies will come with both 4 pin and 8 pin connectors.
The Corsair CX 750 comes only with 8 pin. Should I return the item?
Your motherboard has an 8 pin connector anyway. Why wouldn't you just use that?
Most 8 pin cpu power connectors split into 2 4pin
