ATX1.x used a 20-pin connection to the mainboard. ATX2.x added a 4-pin 12VDC feed (which may be appended to the 20-pin connection or offset elsewhere on the mainboard) and a 6-pin 3.3 and 5 VDC booster plug. If your mainboard has these receptacles, you need the cords plugged into them - either from an adaptor on an ATX1.x supply of adequate size, or from the supply board of an ATX2.x supply.
Don't bung yourself trying to use a Dell power supply without an adaptor, the cheapo home Dell lines use a customised power supply connection! Adaptors are needed to allow use of a Dell PSU with a standard board or a standard PSU with a Dell board...
