Power supply 2.0 work with a P45 mb

Specs: Windows Vista, e2180
I don't have a 2 x 4 12v plug on my motherboard. It says you can use 2 x 2 12v plug on the motherboard. There suppose to be a cap covering the side not to use from what i can understand and there is not. My question do i use the side towards the back panel or the side towards the front panel.

I may just give in and buy a 2.2v power supply. I really don't need to spend money if not necessary. Thanks

Sorry I'm bad with words. I meant to say my motherboard has a 2 x 4 12v plug but powersupply has only 2 x 2 12v.

Read the manual? Page 23:

"The ATX_12V_2X4 power connector is compatible with power supplies with 2x2 12V power connector. When using a power supply providing a 2x4 12V and power connector, remove the protective covers from the 12V power connector and the main power connector on the motherboard. Do not insert the power supply cables into pins under the protective covers when using a power supply providing a 2x2 12V power connector."

I read those pages 5 times. Wishing for more information. The problem was Gigabyte forgot to put the protective cover on the female. So, I had a 8 pin female and 4 pin male and wasn't sure.

I contacted Gigabyte and spoke to a support tech. He said it's the four pins towards the front of the motherboard.

I believe if you had looked closely & compared the 4-pin plug to the 8-pin connector you'd find that they're both keyed & can only be plugged together one possible way.

Here's a close-up of the 4-pin ATX12V plug...notice that two pins are square & two have angled corners:


Now look at the 8-pin EPS12V connector:


It should be obvious which way the clip on the plug should go, so it's just a matter of connecting the plug to the 4-pins on one end of the 8-pin connector or the 4-pins on the other. And because of the way the pins are shaped, one end will work, the other will not...you can't do it wrong unless you really force it.
