2x4 12V connector

[Europa2010AD]

I have a Intel Q6600, 4gb of Crucial Ballistix RAMs, 2x Seagate 500Gb HDD, 2x Asus HD 4850 TOP connected to my GIGABYTE GA-EP45-UD3P P45 Motherboard.

According to the Motherboard's manual, it says that "use of a power supply providing a 2x4 12V power connector is recommended by the CPU manufacturer when using an Intel Extreme Edition CPU (130W)"

Does this mean in addition to the main power supply (2x12 Main Power Connector), the 2x4 12V connector should be connected as well?

I know my Q6600 is not an Extreme Edition CPU, but should I still go ahead and connect the 2x4 12V power as well since I'm powering 2 graphics card? Or is that not recommended?

Thanks a lot for the help!

the 24 pin should be connected to the mother board regardless.

the 2x4 pin is the cpu power connector. cpu connectors come in 2 types, a square 2x2 4pin adaptor or a rectangular 2x4. if available it is always best to use the 2x4.

The 12V cable that comes out of my power supply (Corsair TX650W) splits into two adaptors, each 2x2 4pin. The CPU power connector on my Mobo is 2x4 8pin, so I suppose I should just plug both 2x2 4pin adaptors to it?

I have the same issue and same mobo except I have a 2x2 and a 2x3 but no 2x4. THe mobo would not power up the fan till I connected the 2x2 and now boots but keeps rebooting soon after getting the Windows safe boot screen. Do I need a new PSU with the 2x4 or do I have a bad memory chip?

If you have an 8 pin mobo connector and a 8 pin (or 2x4 pin) connector on your PSU then connect all 8 pins. You can run the 8 pin mobo socket with just a 4 pin connector but if you have a high wattage CPU it is safer to run that electricity through the 8 pins rather than just 4.
