"The TC-750PD2 has a 24-pin motherboard plug only, not the 20 + 4-pin add on style common with other PSU's designed to work with 20 and 24-pin motherboards. There is a single ATX 12V 4-pin power plug, as well as the EPS 12V 8-pin connector used for Intel based server boards. The main 24-pin power line is the only one sleeved on this PSU and all of the power lines are about 19 inches in length."
