Re: GA-EP45-UD3R atx_12v_2x4 8 pin
No adapter required. And as per PowerGiga's link there appears to be a cover over half of the socket by default anyway. So plug in 4 pin plug 2x2 in the exposed half.
What are my options? Can the PS 4 pin connector be plugged into the 8 pin header? Do I need some kind of adaptor? Please don't tell me I need to upgrade the PS because that means I'm going over budget on the build. System will be used for light Office applications and internet use. No gaming, no overclocking, etc. RAID being used in RAID 1 configuration (guy is paranoid about losing data but too lazy to use a backup drive!).
If you are Not using one of the "Extreme" Intel CPU's and opting say for one of the 45nm Cpu's such as the E8xxx series then the 2x2 (4pin) atx 12volt connector should be more than sufficient.
