By default, my Asus P5B Deluxe mobo had a cap over 4 of the pins on the 12V connection, leaving 4 pins pins exposed. The HX 620 has both a 4 pin and an 8 pin 12V connector, so is it better to use the 8-pin connector or the 4-pin connector, or does it not make any difference ?
I would guess the 8-pin is better as the power is spread over 8 pins instead of 4.
