I have a raidmax smilodon case with 500w power supply. I am looking at buing a gigabyte GM-MA785GM-US2H m/b. The power supply in the case has two (2) 2X2 connectors, a 2X3 connector and a 2X12 connector. The M/B has a 2X4 socket for CPU Power. I want to know if I can group the two 2X2 connectors into the 2X4 socket?

I do not want to buy the M/B if it will not work with my case and power supply.

Thanks for all help.

Can you list a link to your're PSU. The CPU requires a 4/8 pin 12v auxillary power connector from the PSU. A single 4 pin 12v from the PSU is sufficient. If the system is running a higher wattage quadcore unit, the second 4 pin would be needed to provide a better ground to the connection. 12v is 12v. By 4 pin or 8 pin. The second 12v 4 pin connectore provides a better ground, not more 12v power.

Thanks for responding Badge. The closest I came to a link was from newegg.com http://www.newegg.com/Product/Product.aspx?Item=N82E168... this is the power supply and has photos and one is the output color coding and amperage. The 2 2X2 connectors one is shown with the main power connection the other is two yellow wires and two black wires. I believe the second connector is two grounds and two 12V 38A connections.

The MB header will be a single 4 pin or dual 8 pin header. A single 4 pin 12v connector will supply power to the CPU. If the PSU has only a single 4 pin 12v for the MB CPU power header, plug the 4 pin in there (to one side of the header). The link to the PSU doesn't work.

Yeah, looks like that PSU has a 4 pin 12v auxillary CPU power connector. That connector will plug in to one side of the 8 pin MB header to supply power to the CPU.

Like I said, an 8pin 12v auxillary power connector from the PSU will not supply more 12v power, only a better ground or source of the 12v power from the PSU.

LittleKeith, Look closely at the connectors you've got. What I think you have is a 2x10 M/B power connector and a sidecar for it 2x2 that turns it into a 2x12 - to fit both 20 and 24 M/B plugs. That's what is showing on the page you linked.

The 2x2 that attaches to the 2x10 should have 3 colors in the wiring, the 2x2 that connects to the CPU only 2 colors -- I think! There's usually some flimsy way to attach the 2x2 to the side of 2x10.

The 2x2 for the CPU should be "idiot-proof" and only go into the right 4 holes of the 8. You don't need to fill the 8 holes for the CPU - 4 is plenty.
