Hello Flopster,
Such power adaptors exist but are not recommended.
The P4 (RDRAM and many others system boards) requires ample 12 volt power that Intel decided required more power then the traces on a system board could handle reliably. Using the appropriate supply, the needed 12volt power is available directly to the system board and close to the regulators.
I mesured 3.5 amps drawn via the 4 pin molex connector for the P4 on the recent build I had just done. Otherwise, this power would have to be derived from a device power connector via an adaptor which you are considering.
Many power supplies have minimal wiring for such a connection at being about 20-18 guage wire. Now you have 2 possible connections to become problematic as opposed to one.
I have seen users building P4s without using the additional connector and simply relying on the system board traces to route 12volt power to the system board regulators (VRM). I recommend against this practice as the traces arn't designed for this kind of duty.
