I've never seen a power supply that has no 4-pin Molex connectors; are you sure it only has SATA power connectors? What kind of power supply do you have?
Generally its a bit strange to have a new/special PC with an old PATA drive; if its compact you should use 2.5" SATA notebook HDDs or even SSDs. But you can ofcourse buy a SATA power -> Molex adapter, though they are not that common.
